" This minute speck, \\ hich appears to be adult, has no salient 

 characters. The periostracum seems absent and there is no sculp- 

 ture beyond the lines of growth ; the suture is very deep and the 

 whorls very convex. It belongs to the group of C. tuThinatum , 

 Sykes, but it is much smaller, and more elevated in proportion to 

 its breadth ; the umbilicus is also narrower." {Sykes.)

Original description: — "Testa subaperte umbilicata, depresso- 

 conica, albida. glabra, uitidula, epidermide decidua cornea, ad 

 anfr. ultimum transverse fusco-strigata, induta ; spira conica, 

 apice acuta ; sutura profunda ; anfr. 4 rotundati, celeriter 

 crescentes, ultimus cylindraceus ; apevtura parum obliqua, circu- 

 laris, prope umbilicum parum sinuata, superne vix angulata ; 

 perist. duplex, externum brevissime expausum, internum por- 

 rectum, acutum, continuum; umbilicus perspectivus. Operculum 

 baud immersum, duplex, internum corneum multispirum, externum 

 testaceum, anfractuum margiuibus lamella spirali, albida, scabra ad 

 anfr. externos perelevata et versus centrum incurvata, quasi 

 convexa, munitis.

"Nearly allied to Cyclotus filocinctns, Benson, by the peculiarity 

 of its operculum, this shell is distinguished by its smaller size, 

 more depressed form, and less expanded peristome, by the absence 

 of the marked sculpture of C. Jilocinctus, and by the epidermis 

 being lighter in colour and marked by brown transverse streaks 

 on the last ^^•horl. That of C. Jilocinctus is hispid. . . . The 

 construction of the operculum is very peculiar. The testaceous 

 spiral lamina being very much more raised towards the exterior 

 than towards the centre, and being curved inwards, the interior 

 whorls of the operculum are almost concealed and the appearance, 

 unless very closely examined, is that of the operculum of a Turbo 

 hollowed out at the centre. The lamella in C malabaricus is 

 rather more elevated than even in C. filocinctus.'^ {Blanford.)
