CYCLOPHORUS.—P tate I. 
liculatd, circa umbilicum leviter lineari-fasciatd ; an- 
fractibus depresso-convewis, levibus, partim granoso- 
striatis ; apertura feré circulari, labro reflexo. 
Tue Matay Cycropyorus. Shell rather largely umbi- 
licated, somewhat transversely turbinated; whitish, 
banded and freckled with reddish chestnut, narrowly 
pale at the periphery, then rather narrowly dark- 
banded, band here and there articulated, faintly li- 
nearly banded around the umbilicus; whorls de- 
pressly convex, smooth, partially granosely striated ; 
aperture nearly circular, lip reflected.

Few naturalists will be inclined to regard this species as 
anything more than a local variety of the Pegu C. specio- 
sus. The type specimen has a double lip to the aperture ; 
but this appears to be rather an accidental development 
than a specific character. 
Species 3. (Fig. a, 6, Mus. Cuming.) 
CycLopHoRUS AURANTIACUS.  Cycl. testa perampliter 
excavato-umbilicatd, subtransverse turbinatd, solidd, 
fulvescente-albd, rufo-castaneo tincta et lentiginosd, ad 
peripheriam anguste pallida, deinde late saturate fas- 
ciatd ; anfractibus depresso-convewis, superne spiraliter 
lirato-striatis ; aperturd feré circulari, ampla, labro 
eleganter refleco, aurantio. 
THE oraNGE CycLopHorus. Shell very largely exca- 
vately umbilicated, rather transversely turbinated, 
solid, fulvous-white, stained and freckled with red- 
dish-white, narrowly pale at the periphery, then 
broadly dark-banded ; whorls depressly convex, spi- 
rally ridge-striated at the upper part ; aperture nearly 
circular, large, lip elegantly reflected, orange.

This fine species is distinguished by a large subangu- 
| larly excavated umbilicus and inflated aperture, with a 
boldly reflected orange lip. 
Species 4. (Fig. a, 6, Mus. Cuming.) 
CycLopHorts speciosus. Cycl. testé subampliter umbi- 
licatd, solidd, subtransversée turbinatd, albidd, rufo- 
castaneo plus minus tinctd et lentiginosd, interdum 
fasciatd, infra peripheriam late saturatd, circa umbi- 
licum lineari-fasciaté ; aperturd fere circulari, labro 
late reflexo. 
THE HANDSOME CycLopHoRus. Shell rather largely 
umbilicated, solid, somewhat transversely turbinated, 
whitish, more or less stained and freckled with red- 
dish-chestnut, sometimes banded, broadly darkened 
below the periphery, linearly banded around the um- 
bilicus; aperture nearly circular, lip broadly re- 
flected.

Cyclophorus speciosus, Pfeiffer. 
Hab. Pegu, Burmah. 
The umbilicus is not so excavately enlarged in this 
species as the preceding, and the shell is smoother, but 
the two species are exceedingly near.
