given), including B. signatus, B. bilabiatus, B. goniostomus, and
B. sulcatus.” “ The only other group of Bulimi resembling the St.
Helena shells occurs in the Pacific Islands ; B. calidonicus, at
Mulgrave Island, B. auris-zovince, at the Solomons; and B. shongi,
in New Zealand.”
*B . d a r v i n i a n u s , Porb.—-With the following six species, all
of which are natives of the Island, this shell is now found only in a
semi-fossil state, embedded in the surface-soil in the ravines formed
by rain, on the north-eastern quarter of the Island, at altitudes from
1200 to 1700 feet above the sea. They are all distinguished by
being slenderer and smaller than the last species. Figured by the
late Professor Forhes in “ Proceed. Geol. Soc.,’; March 10, 1852,
pi. v. f. 1.
*B . h lo f e ld i , Forb.—Found in the surface-soil on the Side-
Path road above The Briars. Figured Ibid. pi. v. f. 2.

*B . subplicatus, G. B. Sow.—Figured Ibid. pi. v. f. 6. Also
described in appendix to Mr. Darwin’s work on Volcanic Islands,
p. 155. See Cochlicopa subplicata.
*B . t e r e b e l l u m , G. B. Sow.—A species more cylindrical in
form than the last. Figured Ibid. pi. v. f. 5. Also described in
appendix to Mr. Darwin’s work on Volcanic Islands, p. 155. See
Cochlicopa terebellum.
*B . f o s s i l i s , G. B. Sow.—Figured and described with the last
species, pi v. f. 4. Found in the surface-soil on Side-Path road
above The Briars. See Cochlogena fossilis.
*B . r e l e g a t u s , Benson.
*B . h e le n a , Quoy.—A stout, opaque shell, about three-quarters
of an inch in length, found under the dying shrubs on The Barn, at
an altitude of 2000 feet above the sea. I t is a native, and although
the shells are now dead, they appear of more recent date than the
former species, and are of a South African, Mozambique, and
Seychelle Island type.
Pupa, Lamarck.
P . u m b i l i c a t a , Draparnaud.— A little British Snail, probably introduced
in the earth with plants, easily distinguished by its
minuteness. I t is very abundant on the high lands, where, in every
garden or damp spot, it is found in large numbers clinging to
rotten wood, stumps of trees, and old palings.
Achatina, Lam.
*A. exulata, Benson.—Both this and the following species are
now found only in a semi-fossil state embedded in the surface-soil on
the Side-Path road above The Briars, &c.

*C. lurida, L.—A rather large dark brown shell, about an inch
and three-quarters in length, picked up somewhat abundantly, but
not alive, on the windward coast.

spotted or mottled in appearance; found under similar circumstances

an inch long, brown in colour, with spotted sides, found with the
other species.
C. moneta, Linn.—The oommon white money-cowrie is occasion-

often carried about in ships, especially those trading on the coasts of
Africa, it may possibly have fallen overboard in ' the roadstead
