Species 92. (Mus. Cuming.) 
CyYcLOPHORUS CONVEXIUSCULUS. Cycl. testd ampliter 
perspective umbilicatd, convexo-depressd, fuscescente- 
corned, epidermide fuscd confertim membranaceo-pli- 
cata indutd; anfractibus perangustis, declivi-rotundatis, | 
ad peripheriam obtuse carinatis ; apertura circulari, 
labro simplict. 
THE MODERATELY CONVEX CycLopHorvs. Shell largely 
perspectively umbilicated, convexly depressed, brown- 
ish-horny, covered with a brown epidermis, which is 
closely membrane-plaited; whorls very narrow, slo- 
pingly rounded, obtusely keeled at the periphery; 
aperture circular, lip simple. 
PFEIFFER, Pro. Zool. Soc. 1855, p. 104. 
Hab. Cape of Good Hope ; Macgillivray. 
Chiefly distinguished by the peculiar structure of its 
epidermis, which is developed in close-set membranaceous 
folds. 
Species 93. (Mus. Cuming.) 
CycLopHoRus cuspipatus. Cycl. testd subampliter pro- 
fundé umbilicatd, acuminato-conoided, fuscescente, spira 
peculiariter torto-elevatd ; anfractibus angustis, liris 
tenuibus subdistantibus pilosis spiraliter carinatis, ad 
peripheriam subacute angulatis; aperturé circulari, 
labro simplici, paululum reflexo. 
THE POINTED CycLopHorus. Shell rather largely deeply 
umbilicated, acuminately conoid, spire peculiarly 
twistedly raised, brownish; whorls narrow, spirally 
keeled with fine, rather distant, hairy ridges, rather 
sharply angled at the periphery ; aperture circular, 
lip simple, a little reflected. 
Cyclostoma cnspidatum, Benson, Ann. and Mag. Nat. Hist. 
1851, vol. viii. p. 189. 
Hab. Neilgherry Hills; Jerdon. 
Singularly characterized by the spire being tortuously 
raised, giving to the shell the form of a little pagoda.

THE wWoopEN CycLopHorus. Shell very narrowly um- 
bilicated, conoidly turbinated, brownish, covered with 
a thin obliquely membrane-plaited epidermis ; whorls 
flatly convex, rather flat beneath; aperture obliquely 
circular, small, lip a little reflected, margins dis- 
joined. 
| Preirrer, Pro. Zool. Soc. 1857, p. 112. 
| Hab. New Zealand. 
A distinct conically turbinated form, with an unusually 
small umbilicus. 
Species 95. (Fig. c, 6. Mus. Cuming.) 
CycLopHorus paRvuS. Cycl. testd subampliter profunde 
ambilicatd, depresso-turbinatd, apice subacutd, ful- 
vescente-corned, castaneo radiatim flammata, flammis 
subdistantibus; anfractibus angustis, declivi-rotundatis, 
ad suturas impressis, liris tenuibus hic illic spiraliter 
cinctis ; apertura circulari, labro simplict. 
THE sMALL CycLtopnorus. Shell rather largely deeply 
umbilicated, depressly turbinated, rather sharp at the 
apex, fulvous-horny, radiately flamed with chestnut, 
flames rather distant; whorls narrow, slopingly 
rounded, impressed at the sutures, encircled here and 
there with fine ridges ; aperture circular, lip simple. 
Cyclostoma parvum, Sowerby, Pro. Zool. Soc. 1843, p. 66. 
Cyclophorus parvus, Gray. 
Hab. Philippine Islands ; Cuming. 
Of semitransparent horny substance, conspicuously rayed 
with chestnut flames, which are unusually straight and dis- 
tant from each other. 
Species 96. (Fig. a, 4, Mus. Cuming.) 
CYCLOPHORUS TRILIRATUS. Cycl. testd modicé excavato- 
umbilicatd, globoso-turbinatd, tenui, corned, sub epider- 
mide subhispidd castaneo-rufo conspicué radiatim flam- 
mata; anfractibus declivi-rotundatis, liris tenuibus 
tribus aut pluribus spiraliter cinctis ; apertura rotun- 
datd, labro fusco, tenué reflexo. 
THE THREE-RIDGED CycLopHorus. Shell moderately 
excavately umbilicated, globosely turbinated, thin, 
horny, conspicuously radiately flamed with chestnut-
