CYCLOPHORUS. 
Puate XV. 
Species 66. (Fig. a, 4, c, Mus. Cuming.) 
CycLoPHoRUS ANNULATUS. Cycl. testé perampliter pa- 
tentissime umbilicatd, depressissimd, subdiscoided, oli- 
vacea, plerumque castaneo radiatim maculata ; anfrac- 
tibus anguslis, transversim dense ruguloso-striatis, 
juata suturas canaliculato-depressis, deinde rotundatis ; 
apertura parca, fere circulari, labro subcalloso, parum 
reflexo. 
THE RINGED CycLopHorus. Shell very largely and 
very openly umbilicated, very depressed, rather dis- 
cold, olive, generally radiately blotched with chest- 
nut; whorls narrow, tranversely densely wrinkle- 
striated, canaliculately depressed next the sutures, | 
then rounded; aperture small, almost circular, lip 
rather callous, but little reflected.

Cyclophorus annulatus, Pfeiffer. 
Cyclophorus deplanatus, Pfeiffer. 
Cyclophorus loxostoma, Pfeiffer. 
Cyclophorus Thwaitesii, Pfeiffer. 
Cyclophorus Parapsis, Benson. 
Hab. Ceylon; India. 
The name given to this species by Troschel is suggested 
by the numerous transverse raised strize, which have the 
appearance of fine close-set rings. I quote Dr. Pfeiffer’s 
C. deplanatus as a synonym on the authority of a specimen 
so labelled (probably by Pfeiffer himself) in Mr. Cuming’s 
collection, and which is represented at Fig. 66a; and I 
believe that C. lowostoma, Thwaitesii, and Parapsis are 
also referable to C. annulatus. 
Species 67. (Fig. a, 6, Mus. Cuming.) 
CYCLOPHORUS TEXTURATUS. Cycl. testd perampliter 
perspective umbilicata, depressd, olivaced, immaculaté ; 
anfractibus rotundatis, striis elevatis rugiformibus un- 
dique irregulariter crispato-reticulatis ; apertura cir- 
culari, fauce cerulescente, labro simplici. 
THE woven CycLopHorus. Shell very largely perspec- 
tively umbilicated, depressed, olive, unspotted; whorls 
rounded, everywhere irregularly crispately reticulated 
with raised wrinkle-like strie ; aperture circular, in- 
terior bluish, lip simple. 
Cyclostoma texturatum, Sowerby, Thes. Conch. Supp. p. 
160*. pl. 31a. 
Cyclophorus texturatus, Pfeiffer. 
Hab. Guatemala. 
An interesting New World type of Cyclophorus, in which 
the surface is sculptured throughout with an irregular net- 
work of waved decussately wrinkled striz. 
Species 68. (Fig. a, 6, Mus. Cuming.) 
CycLopuorus Barrpr. Cycl. testé perampliter paten- 
tissimé umbilicatd, depressissimd, subdiscoided, fulvd, 
castaneo confertim acute fulguratd, ad peripheriam 
saturate fasciatd ; anfractibus angustis, spiraliter densé 
granoso-striatis, supra planulatis, deinde rotundatis : 
apertura pared, circulari, labro subincrassato, haud 
reflexo. 
Barrp’s Cyciopuorus. Shell very largely and very 
openly umbilicated, very depressed, somewhat dis- 
coid, fulvous, closely sharply lightning-marked with 
chestnut, dark-banded at the periphery; whorls nar- 
row, spirally densely grain-striated, flattened above, 
then rounded; aperture small, circular, lip rather 
thickened, not reflected. 
Pretrrer, Pro. Zool. Soc. 1852, p. 144. pl. 18. f. 1. 
Hab. Ceylon. 
Of the same openly-convoluted type as the Ceylon C. 
annulatus, but of quite a distinct sculpture. The whorls, 
instead of being striated transversely, are striated spirally, 
and the strize are granulated throughout. 
Species 69. (Fig. a, 6, Mus. Cuming.) 
CYCLOPHORUS CONFLUENS. Cyel. testd perampliter pa- 
tentissimé umbilicatd, depressd, subdiscoided, fulvo- 
albidd, castaneo supra tinctd et late fasciatd, infra 
remote lineari-fasciald ; anfractibus angustis, rotun- 
datis, transversim decussatim corrugato-striatis ; aper- 
turd circulari, labro simplici. 
THE conFLUENT CycLopHorus. Shell very largely and 
very openly umbilicated, depressed, rather discoid. 
fulvous-white, broadly banded with chestnut above, 
distantly linearly banded below; whorls narrow, 
rounded, transversely decussately wrinkle-striated : 
aperture circular, lip simple.
