CYCLOPHORUS.—Piate XVII. 
though silky; aperture circular, lip simple, a little 
sinuated at the upper part, with the margins dis- 
joined.

Cyclophorus Wahlbergi, Pfeiffer. 
Hab. Natal, South Africa. 
Very similar in general appearance to the South Ameri- 
can Cyclotus translucidus, to which species it was erro- 
neously assigned by Krauss in his ‘Mollusca of South 
Africa.’ 
Species 82. (Mus. Cuming.) 
CYCLOPHORUS sTENOSTOoMA. Cyel. testé laté patente 
umbilicatd, depressi, subdiscoided, fulvescente-albd, 
castaneo-brunneo profuse undato-flammatd ; anfracti- 
bus angustis, juata suturas impressis, transversim densé 
capillaceo-striatis ; apertura obliqué circulari, parva, 
labro coarctato. 
THE CONTRACTED-MOUTH CycLopHorus. Shell broadly 
openly umbilicated, depressed, somewhat discoid, 
fulvous-white, profusely zigzag-flamed with chestnut- 
brown; whorls narrow, impressed next the sutures, 
transversely densely hair-striated ; aperture obliquely 
circular, small, lip pressed inwards.

Cyclophorus stenostoma, Pfeiffer. 
Hab. Neilgherry Mills, India; Benson. 
This species has very much the appearance of a dimi- 
nutive C’. Bairdi, but it will be found on examination that 
the sculpture in one species is transverse, in the other 
spiral. j 
Fig. 85. (Mus. Cuming.) 
The shell here figured is the type of Dr. Pfeiffer’s Cy- 
clophorus lowostoma, collected by Mr. Lear in Ceylon. I 
find it on examination to be identical with C. annulatus, 
from the same locality, of which it is a small specimen. 
From the preceding species, C. stenostoma, it may be re- 
cognized by its more largely open umbilicus and radiately 
blotched painting. 
Species 84. (Mus. Cuming.) 
CYCLOPHORUS PSILOMITUS. Cyel. testd perspective um- 
bilicatd, orbiculari-depressa, virente-luted vel olivaced, 
anfractibus subanguste rotundatis, liris tenuibus undi- 
que regulariter spiraliter funiculatis ; apertura circu- 
lari, labro simplici. 
THE FINELY CORDED CycLostoma. Shell perspectively 
umbilicated, orbicularly depressed, greenish-yellow 
or olive; whorls rather narrowly rounded, regularly 
spirally corded throughout with fine ridges; aperture 
circular, lip simple. 
Cyclostoma psilomitum, Pfeiffer, Pro. Zool. Soc. 1851, 
p. 250. 
Cyclophorus psilomitus, Pfeiffer. 
Hab. Venezuela. 
The sculpture is much more evenly defined in this 
species than in C. alternans, Forbesianus, or rufescens. The 
ridges are perfectly equidistant and uniform throughout.
