given), including B. signatm , 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 Hew Zealand.” 
*B. darvinianus, Forb. — 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 Forbes in “Proceed. Geol. Soc.,” March 10, 1852, 
pi. v. f. 1. 
*B. blofeldi, Forb. — Found in the surface-soil on the Side- 
Path road above The Briars. Figured Ibid. pi. v. f. 2. 
*B. sealeianus, Forb. — Figured Ibid. pi. v. f. 3. 
*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. terebellum, 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. fossilis, 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 Cocldogena fossilis. 
*B. relegatus, Benson. 
*B. helena, 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. It 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.

P. umbilicata, Draparnaud. — A little British Snail, probably in- 
troduced in the earth with plants, easily distinguished by its 
minuteness. It is very abundant on the high lands, where, in every
