Puate III, 
Species 14. (Pig. @, 4, c, Mus. Cuming.) 
LEPTOPOMA REGULARE. Lepé. testd modicé subeacavato- 
umbilicatd, globoso-conicd, pellucido-albd, castaneo- | 
fusco plus minus undato-strigatd, anfractibus declivi- 
rotundatis, usque ad peripheriam prominente filoso- |

THE REGULAR LEPTOPOMA. 
eavately umbilicated, globosely conical, transparent- 
white, more or less wave-streaked with chestnut- | 
brown, whorls slopingly rounded, prominently thread- 
ribbed as far as the periphery; aperture nearly cir- 
cular, lip expandedly reflected. 
Cyclostoma regulare, Pfeiffer, Pro. Zool. Soc. 1851, p. 244. 
Leptopoma regulare, Pfeiffer. 
Hab. Philippine Islands. 
The thread-like ridges with which the whorls of this 
species are encircled between the periphery and the suture 
are rather strongly developed. 
Species 15. (Fig. a, 6, Mus. Cuming.)

lato-flammatd, anfractibus rotundatis, levibus, sub lente 
densé minuté striatis; aperturd rotundatd, labro late 
Lept. testa anguste subexcavato-

Tue GuLAssy Leprorpoma. Shell narrowly rather exca- 
vately umbilicated, transparent-white, variously reti- 
culately flamed with reddish chestnut, whorls rounded, 
smooth, beneath the lens densely minutely striated ;

Leptopoma vitreum, Pfeiffer. 
Dermatocera vitreum, Adams. 
Hab. New Guinea, New Ireland, New Caledonia, Philip- 
pine Islands, Java, Neilgherry Hills, India. 
A smooth, often richly-painted species, without ridges 
or keels, widely distributed throughout the East.

LEPTOPOMA PERPLEXUM. Sept. testd modice excavato- 
umbilicatd, depresso-iurbinatd, pellucido-albd, fascid 
pallidé fulvd supra et infra peripheriam, anfractibus 
tumido-rotundatis, suhobsoleté filoso-liratis, ad peri- 
pheriam plerumque carinatis ; apertura circular, labro 
laté plano-expanso. 
THE PERPLEXING Lupropoma. Shell moderately exca- 
vately umbilicated, depressly turbinated, transparent- 
white, encircled above and below the periphery with 
a pale fulvous band, whorls tumidly rounded, rather 
obsoletely thread-ridged, keeled at the periphery ; 
aperture circular, lip broadly flatly expanded. 
Cyclostoma perplecum, Sowerby, Pro. Zool. Soc. 1848, 
p- 63. 
Leptopoma perpleaun, Pfeiffer. 
Hab. Island of Luzon, Philippines; Cuming. 
Distinguished by a depressed convolution and a pecu- 
liarly tumid form. 
Species 17. (Fig. a, 6, Mus. Cuming.) 
LepropoMa L&VE. Lept. testa subangustée excavato-umbi- 
licatd, globoso-conicd, pellucido-albd, castaneo fasciatd 
vel flammata, anfractibus rotundatis, levibus, sub lente 
minute striatis, ad peripheriam subobscuré carinatis ; 
apertura circulari, labro eapanso-reflexo. 
Tue sMooTH LEpTropoMa. 
vately umbilicated, globosely conical, transparent- 
white, banded or flamed with chestnut, whorls 
rounded, smooth, beneath the lens minutely striated, 
rather obscurely keeled at the periphery ; aperture cir- 
cular, lip expandcdly reflected. 
Turbo levis, Wood, Ind. Test. Supp. pl. 6. f. 5. 
Cyclostoma leave, Gray. 
Turbo immaculatus ? Chemnitz. 
Turbo marginellus ? Gmelin. 
Cyclostoma maculosum, Souleyet. 
Leptopoma immaculatum, Pfeiffer. 
Hab. Philippine Islands; Cuming. 
Shell rather narrowly exca- 
It is quite impossible to determine what species of Lep- 
topoma is referable to Chemnitz’s Turbo immaculatus or 
Gmelin’s 7. marginellus, and even if it were, the names 
would be hardly admissible. 
February, 1862.
