 pi. 79, figs. 1-5 (shell, animal, and anatomical details). 



Shell imperforate, globosely depressed, thin, translucent, smooth, 

 polished, pale yellowish horny ; spire almost fiat, suture impressed ; 

 whorls 3|-, convex, rapidly increasing, the last rounded at peri- 

 phery, swollen below ; aperture oblique, roundly lunate : peristome 

 thin, slightly arcuate above, columellar margin subverfical. 



Major diam. 13, miu. 11, height S mm. A smaller specimen is 

 10x5x 6 mm. 



Hah. Andaman Islands, Port Blair. 



Animal in spirit-specimen about 1 h niches long. AVhole body 

 dark, with the shell-lobes conspicuously pale-coloured. Shell- 

 lobes of mantle large. Xo dart-sac ; the spermatheca long and 

 small, expanding at the end into a large pear-shaped sac. 



In each row of the radula there is a very minute rhachidian 

 tooth, terminally bicuspid, fo]lo\^ed by curved bicuspid laterals, 

 towards the margin these laterals show the pectiniform edges 

 characteristic of the genus. Jaw straight, \\ith a slightlv convex 

 edge. 



It will be seen that the teeth of this radula differ considerably 

 from those of S. levicula and its allies.

 [Fig. 77, E, F.] 



This is distinguished from S. dekhanensis by its much hio-her 

 spire, globose form, and smaller size ; whorl's 4 ; the spire is 

 exserted and blunt ; surface smooth, colour pale green and 

 ochraceous. 



Major diam. 10-5, axis (not height) 5-5 mm. Another speci- 

 men measures 13 x 10| x 7 mm. 



Hah. Tinnevelly Hills, Travancore. 



Animal like S. delclmnensis. The lingual ribbon consists of 

 about GS rows, each of about 350 to 400 . 1 . 350 to 400 teeth, very 

 closely packed. The rhachidian tooth is small, unicuspid : lateral 

 teeth long, uniform, and terminally bicuspid, the outermost beino- 

 serrated on the outer side below the bicuspid apex. Jaw leathery 

 as in S. del-haneusis. 



These South-Indian species are most nearly allied to the 

 Andaman S. cJiristiance, 



332. Satiella flexilis, sp. u. 



Shell imperforate, subglobosely depressed, very soft and flexible, 

 scarcely retaining its shape, smooth, moderately polished, diapha- 

 nous, pale greenish ; spire low, but apex slightly prominent, blunt, 

 suture shallow ; whorls 4i, convex, the last rounded at the
