CYCLOPHORUS. 
Prate VI. 
Species 22. (Fig. a, 6, Mus. Cuming.) 
CycLopHorus Proturatus. Cycl. testd modicé umbili- 
catd, subdepresso-turbinata, rufo-castaned, strigis fulvis 
parvis undatis profuse reticulata, anfractibus angustis, 
levibus vel obsolete liratis, juxta suturas declivi-planis, 
deinde rotundatis ; apertura parviusculd, labro incras- 
sato, parum reflexo, versus umbilicum sublingulato. 
THE EMBROIDERED CycLopHorus. Shell moderately 
umbilicated, rather depressly turbinated, profusely 
reticulated with small waved fulvous streaks, whorls 
narrow, smooth or obsoletely ridged, slopingly flat- 
tened next the sutures, then rounded; aperture 
rather small, lip thickened, but little reflected, 
slightly lingulate towards the umbilicus.

Cyclophorus picturatus, Pfeiffer. 
Hab. Philippine Islands; Cuming. 
The shell here figured, and not that figured in Kiister’s 
edition of Chemnitz, Conch. Cab. pl. 45. f. 13, 14, is 
the true type of the species in perfect condition. It is 
not improbable, however, that C. picturatus, C. tigrinus, 
and C. linguiferus, are all varieties of C. validus. 
Species 23. (Fig. a, 6, c, d, Mus. Cuming.) 
CYcLOPHORUS VALIDUS. Cycl. testd modicé umbilicaté, 
depresso-conoided, ustulato-castaned, superne luteo-al- 
bido angusté fulguratd, subtus immaculatd, anfracti- 
bus juxta suturas depressiusculis, deinde rotundatis, 
undique granoso-striatis et obsolete liratis, liris subdis- 
tantibus; apertura circulari, labro calloso, parum 
reflexo, super umbilicum plus minus lingulato. 
THE sTRoNG CycLopHorus. Shell moderately umbili- 
cated, depressly conoid, burnt-chestnut, marked at 
the upper part with zigzag narrow yellowish-white 
streaks, unspotted beneath, whorls a little depressed 
next the sutures, then rounded, grain-striated and 
obsoletely ridged throughout, ridges rather distant ; 
aperture circular, lip callous, but little reflected, 
more or less expanded into a tongue over the umbi- 
licus.

Cyclophorus validus, Pfeiffer. 
Cyclostoma linguiferum, Sowerby. 
Cyclophorus linguiferus, Pfeiffer. 
Hab. Philippine Islands; Cuming. 
Mr. Sowerby described his C. validum from the speci- 
men Fig. 23¢, d, in 1842, and in the following year he 
described his C. linguiferum from the specimens Fig. 
23 a, 6, in which the sculptured and tongue-like expan- 
sion of the lip are more developed. I believe them to be 
varieties of one species, collected in the intermediate 
states by Mr. Cuming at several of the Philippine Islands, 
and, as mentioned above, it is not improbable that C. pic- 
turatus, and even C. tigrinus, from the same locality, are 
also varieties of this species. 
Species 24. (Fig. a, 6, Mus. Cuming.) 
CycLopHorus voLvuLus. Cyel. testé subeacavato-umbi- 
licatd, conico-globosd, solidd, fulvescente, castaneo va- 
riegatd, infra peripheriam late fasciatd, anfractibus 
rotundatis, levibus; apertura circulari, labro calloso- 
reflexo, albo. 
THE wHorRL CycLopHorus. Shell rather excavately 
umbilicated, conically globose, solid, fulvous varie- 
gated with chestnut, broadly banded beneath the pe- 
riphery, whorls rounded, smooth ; aperture circular, 
lip callously reflected, white.

Cyclophorus ewaltatus, Pfeiffer. 
Hab. Pulo Condore, India. Hongkong, China. 
The shell in Mr. Cuming’s cabinet, lately described by 
Dr. Pfeiffer as C. exaltatum, is, im my opinion, a small C. 
volvulus. It was collected by Mr. Fortune at Hongkong.
