30 ZO'SITIDJE. 



Major diam. 28, rain. 23|, axis 15 mm. A large flat variety 

 from Rajpipla measures 28|, 244, and l'3i. 



Hah. Bombay (common in gardens) ; Eajpipla Hills, east of 

 SuraL I have never been able to trace the occurrence of this 

 species in Malabar. 



The commonest variety is white with three spiral bauds — oue 

 near the suture, one above and one beneath the periphery ; 

 but some shells have the ground-colour brownish with darker 

 bands, and some are white or dark broMii throughout. The 

 parietal wall of the aperture and the area around the umbilicus 

 (periomphalus) are never darker than the adjacent portion of the 

 last whorl. 



The teeth on the radula have the formula 120 . 2 . 8 . 1 . 8 . 2 . 12U 

 (130 . 1 . 130) : the rhachidiau tooth is tricuspid ; the eight inner 

 laterals bicuspid and broad, forming a narrower median line than 

 in other species of the genus, i. e. 17 teeth to 45 in the latter. 

 The admedian teeth ai-e bicuspid up to the 104th.

Similar to A. Icevipes, except that the coloured spiral band close 

 to the suture is wanting, and that the periomphalus or area 

 around the perforation in the base and the parietal or inner wall 

 of the aperture are always chestnut, contrasting with the rest of 

 the wall. As a rule, too, the present species is less depressed and 

 smoother. The coloration varies ; specimens without bands are 

 sometimes found, white or brown throughout.

 &c., from the Ganges to south of the Godavari and west to about 

 80° E.

Shell globose, obliquely striated, generally with fine impressed 

 decussating spiral lines, dull chestnut above, with a white spiral 

 band near the suture and another round the pei-iphery, the inner 

 borders of the white bands darker, a broad white area round the 

 base, periomphalus and parietal wall of aperture dark ; spire 

 convexly conoid, apex blunt ; whorls 5.4, slightly convex, the last 

 rounded at the peripheiT, swollen below ; aperture diagonal, 

 roundly lunate ; peristome small, reflected at the perforation.
