Helix millieri BOURGUIGNAT, Description de quelques especes
nouvelles de mollusques terrestres et fluviatiles des environs de
Saint-Martin-de-Lantosque, Alpes-Maritimes, p. 5. (Cannes, 1880).

This species, says Bourguignat, has its analogues in the high AJps
of Lombardy, at Monte Gleno 2,700 meters, Pizzo Tornello, 2,600,
meters, Monte Codena 2,500 meters ; but these are all undescribed.
It resembles H. debettce Adami, but differs in its more open umbilicus,
more angular periphery, more rapidly increasing whorls, more
exactly oblong aperture, the more approaching margins, etc.

Typical specimens from the original locality are before me, col-
lected by Charles Hedley. It is merely a mountain form of H.
foetens, with no differential characters worth mentioning.

H. SUBZONATA Mouss. var. DEPRESSA Bttg. PI. 31, figs. 46, 47.

Differs from the type in the more depressed form, wider umbili-
cus showing all the whorls, the paler color, wide rufous band and


persistent hairs over the entire surface ; the suture is narrowly but
distinctly marked with white.

H. CONEMENOSI Boettger. PI. 25, figs. 1, 2, 3 ; pi. 31, figs. 52, 53.

Shell depressed-globose, umbilicated, solid, green-straw-yellow
with a rather narrow chestnut-brown band above the periphery.
Surface obliquely striatulate, and showing under a strong lens,
obsolete, dense, spiral striation. Spire convex. Whorls 5, the
earlier slowly, the last very rapidly widening, rather inflated,
deeply descending in front. Aperture very oblique, oval ; peristome
white, somewhat thickened within, outer margin expanded, basal
margin reflexed, columellar margin much dilated, partly concealing
the umbilicus, which is about one-eleventh the diameter of the shell.

H. BROEMMEI Kobelt. PL 31, figs. 54, 55, 56, 57.

Shell openly and deeply umbilicate, but the umbilicus partially
covered by the columellar margin ; depressed-globose, nearly circular
in circumference, roughly and irregularly ribbed-striate, and seen
under a strong lens to be finely granulated by short transverse lines ;
little shining, rather solid, horn-brown with a broad light middle
zone bordered on each side with darker, in which runs a sharply
defined chestnut-brown band ; spire convex with small, submamillar
apex ; whorls 6, slightly convex, rather slowly increasing, separated
by a suture at first linear, but becoming more deeply impressed, and


very narrowly margined with white ; last whorl large, nearly equally
rounded above and below, abruptly and strongly deflected in front.
Aperture oblique, broadly round-ovate, moderately lunate ; brown-
ish-white within, showing the band ; peristome roof-like above ;
outer and lower margin reflected ; columellar margin callously thick-
ened, dilated above and vaulted over a part of the umbilicus.

H. PERITRICHA Boettger. PL 25, figs. 10, 11, 12.

Differs from H. argentellei in being a little higher, the upper
whorls less convex, sutures less impressed, aperture a little wider ;
sculpture wholly different from that of argentellei, consisting of a
broad peripheral band of short, stiff brown hairs, easily rubbed off,
when they leave distinct hair-scars.

itricha KOBELT, 1. c., p. 110, f. 948-951.

In Kobelt's last cited publication he says that the study of ample
material has enabled him to separate the small horn-colored
Canpylseas of Middle Greece from the H. argentellei of Southern
Greece and from H. subzonata ; and to establish their claim to
specific rank under the name peritricha, the chief character of which
is the broad equatorial zone of hairs or hair-scars.

H. KRUEPERI Boettger. PL 31, figs. 48, 49.

Shell rather narrowly umbilicate, the umbilicus about one-eighth
the shell's diameter ; subdepressed-globose, rather thin, hardly
translucent, pale olive-yellow with an indistinct chestnut-brown
band which has no accompanying pale band. The entire surface is
rather thickly beset with short, somewhat recurved hairs, of which
there are about nine upon a square millimeter. Spire depressed,
convex, but the apex rather acute ; there are 5 rapidly increasing
whorls, which are convex and separated by an impressed suture ;
the sculpture is a distinct, rather rough striation ; last whorl very
wide, double as wide as the preceding, well rounded below, strongly


deflected in front. Aperture oblique, broad, of a somewhat irregu-
larly broad-ovate form; peristome whitish, slightly thickened,
expanded throughout, somewhat reflected above ; upper and outer
margins well rounded ; basal margin rather straightened, reflected,
the margins approaching, connected by a thin callus ; columellar
margin oblique, much dilated, covering one-third of the umbilicus.

Taygetos, Greece.

H. (Campy Icea) kruperi BTTG., Nachr.-Bl. D. M. Ges. 1891, p. 84.
KOBELT, Rossm. Icon. n. f. v, p. 110, f. 953'.

It is well distinguished from H. comephora Bgt. by the more
rapid increase of the whorls and especially the dilation of the last
whorl ; but as it is founded upon a single individual (the one figured),
and as Mr. Kriiper has since found the true comephora (which
name being etymologically incorrect has been changed to " comytho-
phora " by Boettger) in the same place, it is not unlikely that the
kruperi is merely an abnormal or pathologic phase of Bourguignat's
species. r

H. POUZOLZI Desh. (Vol. IV, p. 87). The group of which this
species is the type has been monographed by M. Bourguignat,
(Bull. Soc. Mai. Fr. 1888, p. 203), who recognizes 18 species, most
of which are merely individual variations, but some are local races
or varieties. The following names are adopted : H. dinarica Bgt.
(=pouzolzi Dh. not Payr.), Kuzmici Bgt., pacici Mlldff., pellanica
Bgt., montenegrina Ziegl., serbica Mlldff., adriatica Bgt. bosnica Bgt.
(=bosniensis Kob.), varronis Bgt., tchernagorica Bgt., diocletiana
Bgt., soccaliana Bgt., sabljari Bgt., horatii Bgt., biagioi Bgt., breno-
ica Bgt., daniloi Bgt., cantrainei Bgt. The three names, If. dalm-
atina Parr., gravosaensis Miihlf., ragusana Fer. are mentioned by
Bgt. as applied to species of this group, but not accompanied by

Shell narrowly and nearly covered umbilicate, depressed-globose ;
solid, but not very thick; closely, subregularly ribbed-striate,
smoother beneath ; shining ; buff-white, having four bands, the
three upper interrupted ; spire convex, apex small, white ; whorls
5, convex, regularly increasing, separated by a linear hardly impressed


suture ; the last whorl slightly dilated, rotund, slightly flattened
below, deflected in front ; aperture very oblique, almost circular,
little lunate, white within ; pefistome thin, acute, distinctly lipped
with white inside ; margins converging, joined by a scarcely colored
callus ; upper margin straight ; outer and basal margins little

H. CALTABELLOTENSIS Kobdt. PI. 26, figs. 41, 42, 43.

Shell depresed-globular with rather circular circumference, entirely
covered-umbilicate ; the spire slightly conical, the apex small,
smooth, but little projecting. Shell strong, but little shining,
roughly rib-striate, and malleated ; yellowish-white, four-banded, the
upper three bands deep chestnut-brown, interrupted and coalescing
into streaks ; the fourth band upon the under side consisting of square
and arrow-shaped spots; the entire pattern very beautifully distinct.
There are five well-rounded, slowly increasing whorls, which are
separated by a slightly irregularly impressed suture. The last whorl
is somewhat inflated, at the periphery and below convex, suddenly
strongly deflected in front. The aperture is very oblique, lunate-
ovate, and with the exception of the light middle zone deep chestnut-
brown within. The peristome is acute, thin, straight, having a dis-
tinct yellowish-white lip within. The nearly parallel, hardly con-
verging margins are united by a very thin callus. The columellar
margin is arcuate, but the concavity is occupied by a straight com-
pressed fold. The umbilical region is of intense chestnut-brown
color. (Kob.)

H. NADORRICA Westerlund. PI. 26, figs. 28, 29.

Shell depressed-trochoidal or inflated-lenticular ; acutely keeled,
umbilicus wholly concealed ; spire low conical, the apex rather
minute, smooth, somewhat mamillar and projecting; solid; nearly
lusterless, closely ribbed-striate, the ribs occasionally bifurcating, the
interstices malleated ; on the base the sculpture is somewhat vermic-
ulate. Greyish-white with indistinct bands and spots of darker
color appearing in the interstices. Whorls 5, increasing slowly and
regularly, and separated by a linear suture which is somewhat deeply
impressed toward the aperture, and is rendered more prominent by
the projecting keel. The upper whorls are smooth and rounded, the
middle have an acute keel and are impressed above it, the last whorl
is inflated, well rounded above and below, with acute compressed
central keel; more inflated behind the aperture, and at the aperture
somewhat constricted, suddenly and deeply deflected. The aperture
is very oblique, ovate, with a sharp angle outwardly, the peristome
being channelled there ; the throat is chestnut-brown ; peristome
acute, having a yellowish-brown thickening within ; the margins con-
verge slowly and are connected by a thin light brown callus ; the
upper margin is simply arcuate, produced forward ; the basal mar-
gin reflected, arcuately ascending, the concavity occupied by an
acute, compressed, truncated fold ; columellar margin dilated at inser-
tion, appressed, having a chestnut-brown umbilical spot. (JBToft.)

Distinguished from H. paciniana by the more convex whorls and
greater smoothness. Westerlund considers it a form of H. buelowi.

Group of H. sultana.

This group of keeled Iberus is closely allied on one side to H. gualte-
riana of Spain, on the other to the extensive group of H. scabriuscula,


in Sicily and Sardinia. All are characterized by keeled whorls and
microscopic spiral striae.

The following forms belong to this group : H. sultana Morel.,
H. leaehii Fer., H. quedenfeldti Marts., H. viola Pons. and H. cul-
minicola Kob.

The specimens of H. sultana before me have two narrow, light-
brown bands below, one or none above.

H. CULMINICOLA Kobelt, MSS. PL 28, figs. 95, 96, 97.

Shell partly-covered perforate, depressed, thick lens shaped, very
strongly carinated, rather thin, soiled whitish with very faint traces
of three bands above, one below the keel. Surface coarsely obliquely
wrinkled above and below, the wrinkles occasionally branching ;
and under a strong lens the whole surface is densely spirally striated.

Spire low-conic, apex obtuse. Earliest H whorls smoother,
corneous-brown, forming an embryonal shell 'of 2 mill, diameter.
Whorls 4-4i, convex below the suture, then concave toward the
peripheral keel, the last whorl wide, convex below, strongly com-
pressed on each side of the prominent carina, rather strongly
deflexed in front.

Aperture very oblique, oval-rhombic, deeply channelled at the
peripheral keel ; peristome thin, white, expanded, becoming reflexed
at the base and columellar margins.

Highest peak of the Angera Mts., between Tangier and Tetuan
(John Ponsouby.)

I am indebted to Mr. John Ponsonby for this hitherto unpublished
species. It agrees with H. sultana Morel, in the partly covered
umbilicus ; thin, adnate parietal callus, and small embryonic shell ;
but it differs in being smaller and far more coarsely wrinkled. It
agrees with H. viola in the wrinkled surface, but differs in the
smaller umbilicus and especially in the much smaller embryonic

H. VIOLA Ponsonby. PL 26, figs. 50, 51, 52.

Shell narrowly umbilicated, depressed, thick lens-shaped, rather
thin, lusterless, whitish with a faint brown band just above the
carina, a narrower band above it and another below the suture ;
below the cariua there is a faint band. Surface very coarselg rudely
wrinkled above and below, the wrinkles oblique, irregular, sometimes


branching ; and under a strong lens the whole surface is seen to be
densely spirally striated.

Spire low-conic, apex obtuse. Earlier li whorls horny, subcon-
vex; lacking wrinkles, and forming a comparatively large nuclear
shell, about 4 mill. diam. Following whorls wrinkled, rather
rapidly widening, flat ; the last having a strongly compressed periph-
eral carina, swollen below, deeply descending in front. Aperture
very oblique, ovate-rhombic, its contour hardly interrupted by the
parietal wall; lip thin, expanded, continued in a free lamella across
the parietal wall. Alt. 10, diam. 22 mill.

H. viola PONS., in KOB., Nachrichtsbl. D. M. Ges. xxi, p. 12,
1889; Rossm. Icon. n. f. iv, p. 74, f. 648.

This species belongs to a small African group which comprises H.
sultana, H. culminicola and H. viola. It is distinguished from the
former two by the wider umbilicus, slightly elevated parietal wall
of the aperture, and especially by the much larger size of the
embryonal shell, the junction of which with the after-growth is
marked in all these forms by a rather sudden but irregular widening
of the whorl. My description is from specimens received from

H. QUEDENFELDTI v. Martens. PI. 34, figs. 67-71.

Shell covered imperforate, carinated, globose-lens-shaped, solid
but not thick, sculptured with oblique close riblets parallel with the
aperture, which disappear toward the umbilicus; grayish-brown
having five interrupted subobsolete brown bands ; spire roof-shaped,
apex rather large, smooth. Whorls 4, rapidly increasing, the first
smooth, convex, the following flattened, encircled by a thick, more
or less prominent keel ; last whorl large, angulate, inflated below,
abruptly deeply deflected in front ; the carina disappearing on the
latter part of the body-whorl. Aperture very oblique, subcircular,
little lunate ; peristome shortly expanded, whitish ; margins much
converging, joined by a distinct callus; the upper and outer equally
arched ; basal dilated, appressed. (Kob.~)

Icon, v, p. 76, f. 881, 882 ; Nachr.-Bl. 1891, p. 140.


This interesting species may belong to the group of H. sultana
Morel., but it differs from the species of that group in the more
inflated form and the presence of five bands, instead of four, the
normal number in Ibcrus. Kobelt, who has studied and figured the
type specimens, believes that it may prove to be a second species of
the group Allognathus.
