Cy clot us rugatus Guppy. 
Ann . and Mag. Nat. Hist. 3 ser. vol. xiv. p. 246. 
This species is more depressed than the last and is 
readily distinguished by its numerous angular fold-like 
stride and its dark reddish-brown color. Its operculum is 
of somewhat more numerous and narrower whorls than 
that of C. translucidus. Its habitat is in the northern range 
of hills where it is found up to 2000 feet. 
Height 8 millimetres, greatest diameter 17 mill. 
Order Scutibranchiata — (Bhipidoglossa). 
Operculate Mollusca with numerous marginal teeth (un- 
cini) on the dental band. 
Helicina Lamarck 1822. 
Terrestrial Operculata with depressed subglobose shells 
haying a semiovate or triangular aperture, a thickened pe- 
ristome and a semiovate membranaceous (or shelly) oper- 
culum without distinct whorls. 
Helicina nemoralis Guppy. 
Helicina zonata, Guppy Ann. Sf Mag. Nat. Hist. 3 ser. 
vol. xiv, p. 347. 
Helicina nemoralis, ib. Ann. Mag. Nat. Hist. 3 ser. vol. 
xvii, p. 46. 
A smooth pinkish -or yellowish species with a broad band 
of chestnut following the suture to the apex which is of the 
same color. The operculum is dark blood-red except at 
the submarginal nucleus which is yellowish-brown. The 
under surface of the shell is white. * • 
This shell is undoubtedly very nearly allied to Helicina 
jamaicensis, but I consider it distinct. It is found in the 
forests. 
Height 8£ mill., greatest diameter 10 mill.
