VITRINA.—Prarte I. 
increasing, flatly sloping at the upper part, rounded 
at the periphery; aperture very largely open. 
Benson, Journ. Asiatic Soc. vol. v. p. 350. 
Hab. Cherra, on the mountains above Teria Ghat, India ; 
Theobald. 
A very distinct form of Vitrina, composed of only two 
and a half whorls. The coiled portion of the shell is 
therefore very small and simple, while the last whorl is 
largely obliquely produced. 
Species 4. (Fig. a, 6, Mus. Cuming.) 
Virrina Freminer. Vitr. testd orbiculari-depressa, 
olivaceo-corned, solidiusculd, anfractibus convexis, sub- 
rude plicato-striatis ; apertura lunari-ovata, margine 
subinembranaceo. 
FLemine’s Virrina. Shell orbicularly depressed, olive- 
horny, rather solid, whorls convex, somewhat rudely 
plicately striated ; aperture lunar-ovate, margin sub- 
membranaceous. 
Prerrrer, Pro. Zool. Soc. 1856, p. 324. 
Hab. Scinde, India; Dr. Alexander Fleming. 
Of a much rounder form than the preceding species, 
with a broader axis of convolution. 
Species 5. (Mus. Cuming.) 
VITRINA IRRADIANS. V/itr. testd depressd, orbiculari- 
auriformt, fulvescente-corned, anfractibus concentricé 
plicato-striatis, superné lineis impressis spiralibus de- 
cussatis ; apertura oblique lunari-ovatd, margine sub- 
membranaceo. 
Tue RAyED Virrina. Shell depressed, orbicularly auri- 
form, fulvous horny, whorls concentrically plicately 
striated, decussated round the upper part with spiral 
impressed lines ; aperture obliquely lunar-ovate, mar- 
gin submembranaceous. 
PFEIFFER, Pro. Zool. Soc. 1852, p. 156, pl. 13. 
Hab. Ceylon. 
There is a character in this species, which is not of 
frequent occurrence in the genus; the upper half of the 
whorls is engraved with impressed spiral lines. 
Species 6. (Mus. Cuming.) 
VITRINA HIANS. Vitr. test convexo-depressa, subglobosd, 
solidiusculdé, carned, epidermide corned flavicante-oli- 
vaced indutd, spird subemersd, anfractibus modicé pli- 
cato-striatis, ultimo lineis perpaucis spiralibus impressis, 
prope aperturam decussato, apertura rotundato-lunari. 
Tue GapinG Virrina. Shell convexly depressed, rather 
globose, rather solid, flesh-tinted, covered with a yel- 
lowish-olive epidermis, spire a little emerged, whorls 
moderately plicately striated, last whorl decussated 
near the aperture with a few impressed spiral lines ; 
aperture rotundately lunar. 
PrerFFeER, Pro. Zool. Soc. 1848, p. 157. 
Hab. Abyssinia; Dr. Riippell. 
This shell, it will be seen, is convoluted on a broader 
axis than the last, and it is of rather more solid growth.
