the other, seems, in the former case at least, to be, if not
wholly, at least in great part, artificial. The distinction drawn
between the flexibility of the Flustradae and the rigidity of
the Escharadae may perhaps be looked upon as artificial, but
beyond this, the Escharadae exhibit characters, principally in con-
nexion with the avicularia, which would indicate a more natural
distinction between the two groups. The distinction between
Membranipora and Lepralia is in some respects greater and
more natural, as will be indicated in speaking of those genera.

The very curious dentate processes on the edges of the cells
render this species very conspicuous, but the total absence, or
nearly so, of these external appendages in some instances ren-
ders the aspect of various specimens so different, that it requires
some attention to perceive their identity. The peculiar form and
position of the avicularium, and the presence of the internal or
submarginal denticles, are the characteristic diagnostic marks.

Cells, viewed behind, elongated, truncated at both ends, con-

middle, contracted at top and tapering downwards, slightly ex-
panding again at the end. Ovicells immersed, marked with
radiating lines.

3. CARBASEA ARMATA. PL XLIX. figs. 1, 2.

Cells, viewed behind, oblong, narrowed and truncate below ; in
front oval, with a projecting angle on each side about the middle.
Marginal cells each with a large sessile avicularium on the outer

side. Ovicell ?

Hab. South Africa.

The peculiar character of this species, and by which it is readily
distinguished from all others, consists in the presence upon each


of the marginal cells of a large sessile, well-formed avicularium.
The frond attains a height of several inches, having linear trun-
cate segments, slightly dilated towards the end, of a red-brown
colour, generally with one or two dark spots. It appears to be
very abundant in Algoa Bay.

In Krauss' ' Zooph. d. Siids.' p. 35, a new species of Flustra,
or rather of Carbasea, is described under the name of Flustra
marginata, of which figures are also given, minutely and highly
finished. In general habit, and in the front view of the cells,
there is not the slightest resemblance between this form and Car-
basea armata ; but what is given as the back view of the cell, in
Krauss' figure very curiously, bears a striking resemblance to
the front view in C. armata ; and although, in the description of
his species, Krauss takes no notice of the lateral avicularia, they
are very clearly represented in this figure. It might therefore be
supposed that Krauss has confounded two distinct species under
his F. marginata.


Cells oval, irregularly disposed. Frond reticulated. Ovicells
cucullate, immersed.

Retepora cornea, Busk, Voy. of Rattlesn. i. 380.
Hab. Off Cumberland Island, 27 fathoms.

The peculiar reticulated frond of this species is so different
from that of any other of its congeners, as at once to distinguish
it. This form shows very strikingly how artificial some of the
generic distinctions in this class of Polyzoa are ; for, except in the
flexible, horny consistence of the frond, there is no distinction
between C. reticulata and a Retepore.

/3. Aperture occupying only part of the front of the cell.

5. CARBASEA DISSIMILIS. PI. L. figs. 4, 5, 6, 7-

Cells pyriform, much attenuated below. Aperture oval,
anterior. Marginal cells with an acute, short, spinous process
above on the outer side. A sessile projecting avicularium in front
of each cell below the aperture.

F. carbasea, var. /3., Lamk. Ann. s. V. ii. 221. ii. 2d ed.
Hab. Tasmania, Hooker.

This species indicates the transition between the Flustradse
and Cellulariadae. In the form especially of the outer cells, and
in the presence of anterior avicularia upon most of them, it re-
sembles Menipea. The continuous polyzoary however, and the
frondose habit, are sufficient to indicate its true position.

Hob. Bass' Strait, 45 fathoms.

Sometimes small and parasitic, upon Sertularians and Polyzoa ;
sometimes independent, then of large growth, forming dichoto-
mously divided fronds, with strap-shaped, truncate, unequal seg-
ments. From its general resemblance to Lamouroux's figure, it
is not improbable that this may be his F. pyriformis; but as it is
impossible to determine this with certainty, either from his figure
or description, (which are equally applicable to several other spe-
cies,) it has been thought better to give it a new designation.
The one employed is suggested by the form of the ovicells, which
bear a close resemblance to a bishop's mitre.

7. CARBASEA BOMBYCINA. PI. XLVIII. figs. 4, 5, 6, 7.

Cells pyriform, cylindrical, smooth. Aperture small, circular,
superior; a lunate pore in the front of the cell a short distance
below the aperture ; one to four perforations, in a series on either
side of the cell, above and in front. Ovicell marked with radiating
lines. Avicularia 0.

The figure of F. bombycina, given by Ellis and Solander, bears
a sufficiently near general resemblance to the species here desig-
nated C. bombycina, to render it probable that they may be iden-
tical, though this is by no means certain. Considering the locality
whence the present species is derived, it may not perhaps be un-
likely that it represents that intended by Ellis, when he says
(speaking of his F. bombycina, which came from the Bahama
Islands), " I have some elegant specimens from the East Indies
that approach very near to this kind."

Avicularium 0.

Hab. S. Patagonia, Darwin.

Margin of frond divided by shallow notches into small rounded

of the aperture, which is filled in by a very convex transparent

Cells oblong. Aperture nearly as long as the cell, truncate or
square below. Surface behind smooth. Ovicell ? Avicula-
rium 0.
Hab. Tasmania.

The cells in this species most nearly resemble those of Flustra
papyracea : they are however less linear and more rounded at
the top, and not so long in proportion to their width. The little
filling-ill of the aperture at bottom affords a distinctive character,
as does the absence of avicularia, were the generic difference be
tween the two overlooked.


Frond semicircular, undivided, subplicated ; cells oblong, sur-
face behind granulated. Ovicells ? Avicularia 0.

Hab. New Zealand, Hooker.


Cells disjunct, each connected with six others by tubular pro-
cesses ; frond sometimes partially adnate and decumbent.

Diachoris, Busk. Voy. of Rattlesn. 382.

The mode of arrangement and interconnexion of the cells in
this genus is remarkable and highly interesting. It represents,
in fact, a dissected Flustra. The cells are disposed in linear
parallel series, and those of two contiguous series are alternate
with respect to each other. Each cell is connected with one at
either end in the same linear series by a rather wide, short tubu-
lar prolongation, and with two on each side in the contiguous
series by narrower tubes ; so that each cell, except in the mar-
ginal rows, is connected with six others. The species, though
stated to be loosely adnate, are also capable of rising into inde-
pendent erect fronds, like the other Flustradse, and in the other
form would be more correctly described as decumbent than ad-
nate, as they are very loosely connected to the foreign base upon
which they lie.


1. DlACHORIS CROTALI. PI. LXVI. figs. 1, 2.

Cells erect, open in front, with straight sides ; perforated on
the sides and bottom ; a lanceolate appendage articulated to each
upper angle. Ovicell small, conical, superior.

Diachoris crotali, Busk, Voy. of Rattlesn. 382. tab. i. figs. 10, 12.
Hab. Bass' Stijait.

The frond, although, as explained above, not strictly adnate,
as it seems to have no attachments, is usually spread loosely over
other Polyzoa. There is no appearance of a moveable mandible
in the lanceolate appendages, which nevertheless most probably
represent avicularia. These organs are of a lanceolate form, with
an elevated ridge or keel along the back, and slightly concave
beneath : they project in front, slightly depending, and at the
base of each is a rounded eminence.


Cells semi-erect, open in front, oval ; mouth circular with a
thickened and raised margin. A pedunculate and articulated, capi-
tate avicularium attached to the margin of the cell near the top
on each side. Ovicell ?. (Frondose, with cells on both sides,
and also loosely adnate.)

Hab. Straits of Magellan, Darwin ; New Zealand, Lyall.


Cells decumbent, boat- shaped, entirely open; two short mar-
ginal spines on each side near the top. Ovicell ? Avi-
cularium ?

Hab. New Zealand, Lyall. Straits of Magellan, Darwin.

This species approaches very nearly to a Membranipora, and
from the total absence of any moveable appendages, might per-
haps be regarded as a type of a distinct genus : as, however, it is
a solitary instance of the form, and agrees in the structure of the
polyzoary with the above two species, it has been associated with
them and not with the Membraniporidse.
