encircled with rows of arrow-headed chestnut dots, |

Cyclophorus turgidus, Pfeiffer. 
Hab. Bashee Islands, Eastern Archipelago. 
Distinguished in a characteristic manner by the abrupt 
angularity of the last whorl. 
Species 44. (Fig. a, 6, Mus. Cuming.) 
CycLopHorus cUCULLATUS. Cyel. testd angusté umbi- 
bilicatd, depresso-turbinatd, solidd, albidd, fasciis per- 
paucis linearibus fuscis interruptis ornatd, anfracti- 
bus declivi-rotundatis, levibus ; apertura oblique cir- 
culari, labro in unguem elongato. 
THE HOODED CycLopHorus. Shell narrowly umbili- 
cated, depressly turbinated, solid, white, marked 
with a few interrupted linear brown bands, whorls 
slopingly rounded, smooth; aperture obliquely cir- 
cular, lip elongated into a nail. 
Goutp, MS.; Pfeiffer, Mon. Pneumon. Supp. p. 44. 
Hab. Mergui, Burmah. 
This is a very distinct and well-marked species, apart 
from the singularity of the nail-like extension of the lip. 
It would appear to be merely an accidental growth, but 
all the specimens hitherto known of the species are alike 
in this respect. 
Species 45. (Fig. a, 4, Mus. Cuming.) 
CycLoPHoRUs aQuiLus. Cycl. testd excavato-umbili- 
cata, subtransversé turbinatd, depressiusculd, solidd, 
fulva, rufo-castaneo marmorata et fasciatd, juxta su- 
turas maculata, anfractibus superné convexo-declivibus, 
deinde rotundatis ; aperturé subquadratd, labro late 
crasse reflexo. 
THE swarTHY CycLopHorus. Shell excavately umbili- 
cated, somewhat transversely turbinated, rather de- 
pressed, solid, fulvous, marbled and banded with red- 
dish-chestnut, blotched next the suture, whorls con- 
vexly sloping round the upper part, then rounded ; 
aperture somewhat square, lip broadly thickly re- 
flected. 
Cyclostoma aquilum, Sowerby, Pro. Zool. Soc. 1843, p. 61. 
Cyclostoma subtrochiforme, Souleyet. 
Cyclophorus aquilus, Pfeiffer. 
China; Mus. Brit. 
The excavated character of the under surface of the 
last whorl, bordering the umbilicus, imparts to the aper- 
ture a peculiar square form. 
Species 46. (Fig. a, 6, Mus. Cuming.) 
CYCLOPHORUS ZEBRINUS. Cycl. testd angusté excavato- 
umbilicatd, subtransversé orbiculari, depressd, fulvd, 
maculis latis castaneis strigisque undatis irregulariter 
varigata, anfractibus spiraliter carino-liratis et oblique 
subsquamoso-striatis, superné declivi-convexis, inferne 
acuté angulatis et carinatis ; apertura circulari, labro 
crassé reflexo. 
ZEBRA-MARKED CycLopHorvs. Shell narrowly ex- 
cavately umbilicated, somewhat transversely orbi- 
cular, depressed, fulvous, irregularly variegated with 
broad chestnut blotches and waved streaks, whorls 
spirally keel-ridged, and obliquely squamosely striated, 
slopingly convex round the upper part, sharply an- 
gled and keeled at the lower; aperture circular, lip 
thickly reflected.
