Nelicina barbata Guppy. 
Annals Sf Magazine Natural History, 3 ser. vol. xiv, p. 237. 
A smaller and more depressed species than the preceding, 
dark colored and zoned with three or four indistinct bands 
of color. When alive it has a dark-colored hairy perios- 
traca. It is found on all parts of the island where the 
ground is somewhat open ; it rarely occurs in the forest. 
Height 5 mill., greatest diameter 6£ mill. 
The nearest relation of this species seems to be N. Dyso - 
ni of Honduras. The same or a closely-allied species oc- 
curs in some of the Antilles, but I have been unable to as- 
certain if it has been specifically determined. 
Adamsiella Pfeiffer 1851. 
Terrestrial Operculata with pupiform or oblong turreted 
shells having a small circular or subcircular aperture with 
a double or expanded continuous peristome and a thin pan- 
cispiral operculum with a subcentral nucleus and the outer 
edge detached. 
Adamsiella arijpensis Guppy. 
Annals Sf Mag. of Nat. Nisi. 4 ser. vol. xiv, p. 246. 
An oblong-turreted shell, longitudinally striate, of a red- 
dish-brown color with several more or less interrupted dark 
bands and an oval aperture having an expanded or double 
peristome of an orange or whitish color concentrically stri- 
ate. Operculum paucispiral, whorls increasing rapidly, 
nucleus transparent. Height 13 mill., diameter 8 mill. 
This species differs very considerably from any other 
Adamsiella that I have seen; and it approaches Cyclostomus 
in many of its characters. It is found on the Cerros of 
Aripo at a height of 2000 — 2500 feet where it lives amongst 
the dead leaves in the forest, frequently suspending itself 
by glutinous threads from branches or the under surface of 
leaves at the height of a foot or so from the earth.
