There is a little difference in form between this and the 
preceding species, but it is scarcely appreciable. The

spire inclines to be more depressed and the whorls become 
narrower but less produced. 
Species 24. (Mus. Cuming.) 
VirRINA CORNEA. Vitr. lestd subdepresse glohosd, pellu- 
cido-corned, tenuissimd, fascid angustd rufo-fuscd supra 
peripheriam cingulatd, spird convexd, parum emersd, 
anfractibus arcuatim plicato-striatis ; apertura oblique 
lunari-rotundata. 
Shell somewhat depressly glo- 
bose, transparent horny, very thin, encircled above 
the periphery with a narrow red-brown band, spire 
convex, but little emerged, whorls arcuately plicately 
striated ; aperture obliquely lunar-rounded.

vol. i. p. 505. 
Hab. Natal. 
A. beautifully transparent shell, of the thinnest hormy 
substance, encircled with a characteristic red-brown band. 
Fig. 25 a, 6. (Mus. Cuming.) 
The shell here figured is the type of Dr. Pfeiffer’s Vitrina 
heliciformis (Pro. Zool. Soc. 1854, p. 296), subsequently 
described by him (Pro. Zool. Soc. 1856, p. 326) as a 
Helix, under the name H. Ophiria. Tt is a thin membra- 
naceous horny shell, with very much the appearance of a 
Vitrina, but is angulated at the periphery in a manner not 
to be found in that genus, and is characterized by a pecu- 
har opal-white milky deposit about the apex. It was col- 
lected at Mount Ophir, Malacca, by Dr. Traill. 
Species 26. (Mus. Cuming.)

Vitr. testa depresse semiglobosi,

apertura oblique lunari-rotundatd. 
THE CRENULATED VITRINA. 
bose, golden horny, transparent, spire flattened, 
Shell depressly semiglo-

cuately plicately striated; aperture obliquely lunar- 
rounded.
