CYCLOPHORUS.—Piats XIV. 
THE INKY CycLtopHorus. Shell rather narrowly umbili- 
cated, rather solid, livid-purple, tinged with blue, 
sparingly flamed with brown; whorls narrow, rather 
flattened above, then convex; aperture circular, lip 
thinly flatly expanded.

Hab. ? 
Nothing is known of the habitat of this species, but it 
is a very characteristic one, distinguished by a peculiar 
livid-purple inky hue. 
Species 63. (Mus. Cuming.) 
CycLopHorus GuimaRasENsIS. Cycl. testd subanguste 
excavato-umbilicatd, tenuiculd, fulvescente, castaneo- 
fusco juxta suturas maculatd, medio lentiginosd, ad 
peripheriam articulatd, infra saturate tinctd ; anfrac- -

THE Guimaras CyYcLOPHORUS. 
excavately umbilicated, somewhat thin, fulvous, spot- 
ted next the sutures with fulvous chestnut, freckled 
in the middle, articulated at the periphery, dark- 
stained below it; whorls flattened at the upper part, 
convex and spirally ridged in the middle; aperture | 
almost circular, lip thinly reflected.

Cyclophorus Guimarasensis, Gray. 
Hab. Island of Guimaras, Philippines; Cuming. 
A prettily articulated species of a rather light semi- | 
transparent substance. 
Species 64. (Fig. a, 6, Mus. Cuming.) 
CycLopHorus Puriiippinarum. Oyel. testd peranguste 
umbilicatd, yloboso-conicd, solidd, albidd, rufo-fusco 
minute reticulato-lentiginosd, ad suturas conspicué an- 
guste maculata, ad peripheriam albidd, deinde saturate 
Sasciata ; anfractibus spiraliter densé liratis, ad suluras 
Shell rather narrowly | 
angusté canaliculatis ; apertura parviusculd, fere cir- 
culari, labro reflexo. 
Tne PHiLipprnE CycLopnorus. Shell very narrowly 
umbilicated, globosely conical, solid, whitish, minutely 
reticulately freckled with red-brown, conspicuously 
narrowly spotted at the sutures, whitish at the peri- 
phery, then dark-banded; whorls spirally densely 
ridged, narrowly channelled at the sutures; aperture 
rather small, circular, lip reflected. 
Cyclostoma Philippinarum, Sowerby, Pro. Zool. Soc. 1842, 
p- 83. 
Cyclophorus Philippinarum, Pfeiffer. 
Hab. Philippine Islands; Cuming. 
A very good distinguishing character of this species is 
that of the sutures being channelled, the sutural dark spots 
being sunk in the channel. 
Species 65. (Mus. Cuming.) 
CYCLOPHORUS ZEBRA. ‘Cycl. testd perangusté umbilicatd, 
globoso-conicd, albida, castaneo-fusco plus minus tincta 
et fasciatd, jucta suturas subobscuré maculata ; anfrac- 
tibus convewis, spiraliter subremote carinatis, juxta 
suturas subcanaliculatis ; aperturé parviusculd, fere 
circulari, labro calloso-reflexo. 
THE zEBRA CycLopHorus. Shell very narrowly umbili- 
cated, globosely conical, whitish, more or less stained 
and banded with chestnut-brown, somewhat obscurely 
spotted next the sutures; whorls convex, spirally 
rather distantly keeled, faintly channelled next the 
sutures ; aperture rather small, nearly circular, lip 
callously reflected.

Cyclostoma Philippinarum, var., Sowerby. 
Cyclophorus zebra, Pfeiffer. 
Hab. Philippine Islands; Cuming. 
Exactly intermediate in its characters between C. Gui- 
marasensis and Philippinarum, and serving to connect the 
three species in one. In C. Philippinarum a sutural de- 
pression indicates the faint channel of C. zebra, which in 
C. Guimarasensis assumes the form of an incised groove, 
and the canal narrows according as the whorls are more 
conically coiled.
