Species 38. (Mus. Cuming.) 
Lepropoma Lowi. Lept. testd minute umbilicaté, globoso- 
turbinatd, fulvo-corned, pellucidd, ad suturas opaco- 
alba: anfractibus rotundatis, spiraliter tenuistriatis ; 
apertura circulari, subinflatd, labro eleganter plano- 
expanso, albo. | 
Low’s Lrpropoma. Shell minutely umbilicated, glo- 
bosely turbinated, fulvous-horny, transparent, opake 
white at the sutures; whorls rounded, spirally finely 
striated; aperture circular, rather inflated, elegantly |

Hab. Borneo; Low. 
A. delicately-transparent, smooth, fulvous, horny shell, 
overlaid with a very slight deciduous opake-white tissue 
next the suture and around the umbilicus.

CILIATUM. 
depresso-turbinatd, sordidé castaned, fulco- 
Lept. testa late excavato-nin- 
et maculata ; anfractibus convexo-declivibus, 
concentrice arcuatim plicato-striatis, ad peripheriam 
angulatis, carinatis, ciliatis ; aperturd pared, rotun- 
data, parum reflexd. 
THE cittateD Lrpropoma. Shell broadly excavately 
umbilicated, depressly turbinated, dark-chestnut, 
streaked and marbled with fulvous; whorls convexly 
sloping, concentrically arcuately plicately striated, 
angled at the periphery, keeled, ciliated ; aperture 
small, rounded, but little reflected.

p. 65. 
Leptopoma ciliatum, Pfeiffer. 
Hab. Island of Luzon, Philippines; Cuming. 
This and LZ. dardatum belong to quite a different type, 
and appear to me to be wrongly placed in this genus. 
They approximate nearer toa similar form of Cyclophorus. 
Species 40. (Mus. Cuming.) | 
LrEPTOPOMA SIGNATUM. 
globoso-turbinatd, lulescente-corned, strigis confertis 
rufo-castaneis undique fulgurata ; anfractibus guxta

exilissimé filoso-liratis ; aperturd circulari, labro cal- 
loso-reflewo, livido-albo. 
THE REMARKABLE Lepropoma. Shell minutely um- 
bilicated, globosely yellowish-horny, 
waved throughout with close-set reddish chestnut 
streaks; whorls rather depressed next the suture, 
then rounded, spirally very finely thread-ridged ; 
aperture circular, lip callously reflected, livid-white.

Leptopoma signatum, Pfeiffer. 
Hab. Borneo. 
turbinated, 
The thread-ridges are extremely faintly indicated in this 
species, but they are certainly present. 
Species 41. (Fig. a, 6, Mus. Cuming.) 
Lepropoma nigricans. Lept. testd subangusté umbili- 
catd, acuminato-turbinatd, nigricante-fuscd, sericed, 
ad suturas obscure strigatd ; anfractibus convewis, un- 
dique oblique confertim plicato-striatis, ad peripheriant 
subobsolete filoso-carinatis ; apertura circulari, labro 
laté calloso-expanso, livido-albo. 
DARK Lepropoma. Shell rather narrowly umbili- 
cated, acuminately turbinated, black-brown, silky, 
obscurely streaked at the sutures; whorls convex, 
obliquely closely plicately striated throughout, rather 
obsoletely thread-keeled at the periphery ; aperture 
circular, lip broadly callously expanded, livid-white.

Hab. ——? 
THE 
A well-defined species, of which the surface has a dark 
silky appearance, from being closely set with raised pli- 
cated striz. 
Species 42. (Fig. a, 6, Mus. Cuming.) 
LmpropoMa BARBATUM. Lept. testd latissimé perspective 
umbilicatd, depresso-turbinata, fulvd, castaneo arcuatim 
tessellata ; anfractibus angustis, converis, ad peri- 
pheriam carinatis, barbatis, supra spiraliter quinque- 
liratis, infra decussatim liratis ; aperturd pared, cir- 
culari, labro tenue reflexo. 
Tue BEARDED Lepropoma. ~ Shell very broadly perspec- 
tively umbilicated, depressly turbinated, fulvous,
