chestnut; whorls narrow, linearly impressed at the 
sutures, transversely membrane-striated; aperture 
circular, lip simple. 
Preirrer, Pro. Zool. Soc. 1856, p. 337. 
Hab. Neilgherry Hills, India; Shiplay. 
This little species has very much the appearance of C. 
parvus, but it has a more depressed spire and is differently 
striated. 
Species 86. (Fig. a, 6, Mus. Cuming.) 
CycLopHorus FoRNICATUS. Cyel. testé ampliter subex- 
cavato-umbilicatd, convexo-depressd, sublenticulari, al- 
bidi, versus apicem rosaced, epidermide tenui fusces- 
cente induté; anfractibus angustis, undique spiraliter 
acuté liratis, ad peripheriam conspicué carinatis, ca- 
rind undulaté ; apertura circulari, labro simplici. 
THE VAULTED CycLopHorus. Shell largely rather ex- 
cavately umbilicated, convexly depressed, somewhat 
lens-shaped, whitish, pink towards the apex, covered 
with a thin brownish epidermis ; whorls narrow, spi- 
rally sharply ridged throughout, conspicuously keeled 
at the periphery, keel a little waved; aperture circu- 
lar, lip simple. 
PFEIFFER, Pro. Zool. Soc, 1852, p. 146. 
Hab. New Hebrides. 
Of all Cyclophori, this little species, from New He- 
brides, is the most prominently keeled at the periphery. 
Fig. 87. (Fig. a, 6, Mus. Cuming.) 
The specimen here figured is the type of Dr. Pfeiffer’s 
Cyclophorus Thwaitesii. I cannot bring my mind to be- 
lieve that it is anything more than a small depressed form 
of C. annulatus, from the same locality.

Species 88. (Fig. a, 6, Mus. Cuming.) 
CyctopHorus AmBornensis. Cyel. testd modicé wmbi- 
licatd, depressé turbinatd, alba, rufo-fusco copiose 
tincté et flammatd ; anfractibus levibus, declivi-con- 
vevis ; apertura circulari, labro paululum reflexo. 
Tae Ampoyna Cyctornorus. Shell moderately umbi- 
licated, depressly turbinated, white, copiously stained 
and flamed with red-brown; whorls smooth, slo- 
pingly convex; aperture circular, lip a little re- 
flected. 
PreirFrer, Pro. Zool. Soc. 1852, p. 144. 
Hab. Island of Amboyna, 
A well-marked brightly-coloured smooth shell, of a neat 
turban form. 
Species 89. (Mus. Cuming.) 
CycLopHorUs caLoconus. Cyel. testd modicé umbili- 
catd, depressé turbinatd, tenui, subpellucidd, olivaceo- 
lutescente, castaneo radiatim strigatd, fascia conspicud 
infra peripheriam ; anfractibus conveais, transversim 
densé capillaceo-striatis; apertura oblique circulari, 
labro simplict. 
THE HOLLOW cone CycLorHorus. Shell moderately 
umbilicated, depressly turbinated, thin, semitranspa- 
rent, olive-yellow, radiately streaked with chestnut, 
with a conspicuous band below the periphery ; whorls 
convex, transversely densely hair-striated; aperture 
obliquely circular, lip simple.

Cyclophorus ceeloconus, Pfeiffer. 
Hab. Neilgherry Hills, India; Jerdon. 
A prettily painted light silky shell, distinguished by a 
conspicuous chestnut band below the periphery. 
Species 90. (Mus. Cuming.) 
The shell here figured is Mr. Benson’s Cyclophorus 
Parapsis, which, together with C. deplanatus, Thwaitesu, 
and loxostoma, all from Ceylon, are, in my opinion, only 
trifling modifications of C. annulatus, Troschel, from the 
same locality.
