VITRINA. 
Piate V. 
Species 29. (Mus. Cuming.) 
VITRINA RUFESCENS. 
rufescente-corned, spira convexd, subemersd, anfractibus 
rotundatis, tenueé plicatis ; aperturd lunari-rotundata. 
THE REDDISH VITRINA. Shell nearly globose, very thin, 
reddish horny, spire convex, rather emerged, whorls 
Vitr. testa sudglobosd, tenuissimd, 
rounded, finely plicated ; aperture lunar-rounded. 
PreirFrer, Pro. Zool. Soc. 1848, p. 106. 
Hab. Island of Mindoro, Philippines; Cuming. 
A bright transparent horny shell, distinguished by its 
globose form. 
Species 30. (Mus. Cuming.) 
ViIrRINA PLANULATA. Vitr. testd depressissimd, auri- 
formi, pellucido-corned, spird planatd, anfractibus 
perangustis, aperturé amplissima, 
perobliqua. 
THE FLaT VirriInA. Shell very depressed, ear-shaped, 
transparent horny, spire flattened, whorls very nar- 
row, picately striated; aperture very large and ob-

Prerrrer, Pro. Zool. Soc. 1848, p. 106. 
Hab. Island of Luzon, Philippines; Cuming. 
plicato-striatis ; 
A very depressed species, approaching to the Peltella 
form of the genus described at Plate X. 
Species 31. (Mus. Cuming.) 
VITRINA PAPILLATA. Vitr. testd depressd, suborbiculari, 
pallidée corned, pellucido-vitred, spird parvd, medio 
papillatd, anfractibus angustis, breviusculis, subtilis- 
simé plicato-striatis ; apertura oblique rotundata. 
THE PAPILLARY ViTrRina. Shell depressed, nearly or- 
bicular, pale horny, transparent glassy, spire small, 
papillary in the middle, whorls narrow, rather short, 
very finely plicately striated; aperture obliquely 
rounded. 
Preivrer, Pro. Zool. Soc. 1848, p. 106. 
Hab. Island of Luzon, Philippines; Cuming. 
Collected in the same locality as the preceding species, 
but certainly distinct. The papillary character ascribed to 
the apex arises from its being a little opakely emerged. 
Species 32. (Fig. a, 6, Mus. Cuming.) 
Virrina DaRrNnaupt, 
virescente-corned, parum nitente, anfractihus declivi- 
Vitr. testa semiovatd, tenuissind, 
convexis, minute malleatis et plicatis, ultimo perablique 
producto ; aperturé ampld, diagonali-ovata. 
Darnaup’s Virrina. Shell semiovate, very thin, green- 
ish horny, but little shining, whorls slopingly convex, 
minutely malleated and plicated, last whorl very ob- 
liquely produced; aperture large, diagonally ovate.

Hab. Sennaar, Nubia; Darnaud. 
This very interesting Nubian type of Vitrina is convo- 
luted in a more than usually diagonal manner. 
face shines with the dullness of an oiled surface.

VITRINA GRANDIS. Vitr. testd depressé auriformi, vires- 
cente-albd, opalino-corned, spird via emersd, anfrac- 
tibus angustis concentricé plicato-striatis et tenuiter 
corrugatis, ad suturas impressis, ad peripheriam ob- 
tusé angulatis ; apertura perobliqua. 
THE LarGE Virrina. Shell depressly ear-shaped, ereen- 
ish-white, opal horny, spire scarcely emerged, whorls 
narrow, concentrically plicately striated, and thinly 
wrinkled, impressed at the sutures, obtusely angled 
at the periphery; aperture very oblique. 
PFEIFFER, Pro. Zool. Soc. 1848, p. 8. 
| Hab. Guinea, West Africa. 
There is little to distinguish this species, excepting co- 
lour, from VY. Sowerbyana, from the same locality; but this 
difference, whatever it may be worth, is remarkable. / 
Sowerbyana is a dark bronze-tinged brown; V. grandis is 
a pale greenish opal-white. 
Species 34. (Mus. Cuming.) 
VITRINA MARGARITA. 
lino-corned, spird plano-convexd, anfractibus declivi- 
Vitr. testa depresso-globosi, hya- 
convewis, latiusculis, confertim tenué striatis ; apertura 
lunari-rotundata. 
THE PEARL Virrina. Shell depressly globose, hyaline 
horny, spire flatly convex, rather broad, closely finely 
striated; aperture lunar-rounded.
