The Western race A. immerita is smoother, with the spiral 

 impressed lines nearly or quite obsolete. It has hitherto only 

 been found in South Canara. According to God win-A listen, 

 Moll. Ind. i, p. 135, the outer lateral teeth of the radula are more 

 numerous in A. interrupta than in A. immerita, but this is scarcely 

 a character that is necessarily of specific value. The number in 

 A. interrupts is 40 . 23 . 1 . 23 . 40 (63 . 1 . 63), so that the median 

 row of large teeth is very broad. In A. immerita it is 

 25 . 24 . 1 . 24 . 25 (49 . 1 . 49). The rhachidian tooth has a cusp 

 on each side, the aclmedian teeth only one on the outer side ; the 

 smaller lateral teeth are pointed, without lateral cusps. [See 

 fig. 17 B (p. 27) also for the jaw and dorsal lobes.] 



b". Globose.
