CYCLOPHORUS. 
Prats VIII. 
Species 30. (Fig. a, 6, Mus. Cuming.) 
The shell here figured is Mr. Sowerby’s var. d of C. 
tigrinum, characterized as having less conspicuous streaks, 
with the aperture orange-brown. The colouring of the 
aperture is more strictly a deep blood-colour, and the 
variety is very peculiar in this respect. 
Species 31. (Fig. a, 6, Mus. Cuming.) 
CycLopHorus CANALIFERUS.  Oycl. testa subampliter 
umbilicatd, conico-turbinatd, albida, fusco marmorata, 
versus apicem purpureo-rosed, infra peripheriam late 
saturate fasciatd, anfractibus dense liratis et striatis, 
rotundatis, ad suturas profundé angusté canaliculatis ; 
apertura parviusculd, circulari, labro simplict, con- 
tinuo, parum reflexo. 
THE CHANNELLED CycLopHorus. Shell rather largely 
umbilicated, conically turbinated, whitish, marbled 
with brown, purple-rose towards the apex, broadly 
dark-banded below the periphery, whorls densely 
ridged and striated, rounded, deeply narrowly chan- 
nelled at the sutures ; aperture rather small, circular, 
lip thickened, continuous, but little reflected.

Cyclophorus canaliferus, Pfeiffer. 
Hab. Philippine Islands ; Cuming. 
Distinguished by a characteristic narrow sutural chan- 
nel, arising from a dropping in the coiling of the whorls. 
Species 32. (Fig. a, 6, Mus. Cuming.) 
CYCLOPHORUS LABIOSUS. 
catd, depresso-turbinatd, solidd, saturate castaned, 
lituris albidis sparsim aspersd, infra peripheriam sa- 
turatius late fasciatd, circa umbilicum alba, anfrac- 
tibus declivi-convexis, dens? granoso-striatis ; apertura 
obliqud, labro incrassatim reflexo. 
THE Lippep CyctopHorus. Shell excavately umbili- 
cated, depressly turbinated, solid, dark-chestnut, 
sparingly sprinkled with whitish marks, darker broad- 
banded below the periphery, white round the um- 
bilicus, whorls slopingly convex, densely granosely 
striated ; aperture oblique, lip thickly reflected.

Fab. ? 
The under portion of this shell resembles that of C. 
oculus-capri, but the upper part is destitute of the keel- 
like ridges which characterize that species. Can it be a 
smooth variety ? 
Species 33. (Fig. a, 6, Mus. Cuming.) 
CycLorHorus Wooptanus. 
bilicatd, orbiculari, depressiusculd, flavescente, maculis

bilicum interdum lingulato. 
Woop’s Cycioruorus. Shell largely umbilicated, or- 
bicular, rather depressed, yellowish, painted next the 
sutures with large square purple-brown blotches, 
narrowly filleted at the periphery; whorls narrow, 
spirally finely ridged and striated, flatly excavated 
next the sutures, then rounded; aperture circular, 
lip thickened, but little reflected, sometimes lingu- 
late over the umbilicus.

Hab. Philippine Islands; Cuming. Java; Mousson. 
Invariably characterized by a row of large purple-brown 
square blotches on the flattened ledge of the whorls next 
the sutures. Specimens with the lip lingulate have been 
separated by Pfeiffer under the name C. appendiculatum.
