The distinctness and usually larger size of the cells in this
species, their having only three to four distant (the two lateral
of which are much stronger than the others) oral spines, which are
almost always, if not always, totally obsolete in the fertile cells,
the peculiar arrangement of the pores, and, above all, the inva-
riable absence of avicularia on each side of the mouth, will suffice
to distinguish it from the deep-sea, thickened, or overgrown form
of L. punctata, figured in PL XC. figs. 5, 6, to the mouth of
which that of the fertile cells of L. annulata bears a very close

Notwithstanding the apparently marked distinction between
the typical forms of L. variolosa, L. ventricosa, and L. Peachii,
some difficulty wdll be found in distinguishing them under cer-
tain conditions of age and overgrowth, or when much worn. In
L. variolosa the ovicell is always deeply immersed, and has in
front of it a single spine, or the stump of a single spine only, on
each side ; the normal number of oral spines in this species ap-
pearing to be two to three (in the former case it constitutes, as
I imagine, L. ovalis, Hassall). In L. Peachii the ovicell is also
immersed, but not so deeply, and always has two, or the remains
of two, oral spines on each side in front of it, the normal number
of these spines being, in this species, six ; w 7 hilst in L. ventricosa,
besides the more erect position, generally, of the upper part of
the cell, the greater elevation of the mouth, &c., the ovicell is,
comparatively speaking, free or much raised, shows, I believe,
no spine in front of it, or one only, and the number of oral
spines is invariably, or nearly so, four. With respect to the asso-
ciation of L. Peachii and immersa, Johnst., there can, I think,
upon inspection of the figures in Brit. Zooph., be no doubt of
its propriety.

Cells distinct above, or raised, immersed at the base, ventri-

more) marginal spines ; surface granular or irregularly striated ;
usually a pointed or broad mucro in front of the mouth. Ovicells

Hab. Estuary of the Thames, Lieut. Thomas, on shell. East

Coast ! Mrs. Gatty ; Busk.

A very peculiar species, though in the costate structure of the
cell approaching L. nitida, and to which it seems, perhaps, too
closely allied. It grows in linear series, which branch out in an
arborescent manner, closely adhering to the surface of dead
shells. These branches, in process of growth, become more and
more crowded, and finally coalesce into a continuous expansion.
I first noticed this form in the year 1852, on some shells dredged
at the mouth of the Thames by Lieut. Thomas, R.N., and
afterwards found it on the coast of Suffolk, near the mouth of
the Orwell ; and about the same time it was found and its pecu-
liarities observed by Mrs. Gatty.


Cells subglobose or ovate, rising in front into an umbo or
short keel ; furrowed, the grooves radiating from the central line ;
mouth suborbicular, with the lower lip straight ; four to six mar-
ginal spines ; a perforation a little below the mouth and above
the umbo.

Notwithstanding the high authority of Mr. Bean and of
Mr. Peach, there is no doubt that Dr. Hassall is quite right in
assigning spines to the margin of the mouth. It is a very pro-
tean species, and in the old and deep-water condition requires
some discrimination to distinguish it.

cesses ; mouth orbicular, unarmed. Ovicell globose, lofty, with

In the absence of ovicells in the specimens in my possession,
it is impossible to determine whether or no the present is identical
with the species figured by Savigny, to which however, in other
respects, it bears a very close resemblance. This form, although
named by Audouin Mangnevillana, is clearly not the one in-
tended by Lamouroux under that appellation (vid. Polyp. Flex.
p. 890. pi. 1. fig. 3. a. B). A species of the same black colour,
and in all respects resembling the present except in the less
obliquity of the mouth and the absence of the raised upper
border, occurs in Gibraltar Bay (Dr. Landsborough). The latter
form is verv like L. reticulata.

As there can be no doubt of the identity of this species with
that figured by Savigny, I have thought it right to apply Au-
douin's name. The species is so peculiar as to require no addi-
tional observations, unless it were to draw attention to the un-
certain occurrence and form of the oral spines in it. The ovi-
cell in the South American forms is of a brownish hue ; and in
all the specimens from that region the cells appear to be much
larger than in the more common European form. The cells ad-
here to the object upon which the Lepralia is placed by means
of a central flattened disc, and not by the entire surface (PI. CIII.
fig. 3).

In a very beautiful and perfect specimen of this species, grow-
ing apparently on Laminaria, for which I am indebted to the
kindness of Dr. Landsborough, the lower lip is produced into a
very distinct and curiously formed mucro, and the structure of
the lateral avicularia is remarkably well displayed. The cells
are smooth and hyaline, and scarcely, if at all, ventricose, and I


am therefore very much in doubt, with Dr. Johnston, whether
this form is to be referred to the C. bimucronata of Lamouroux.
