Hab. Bombay, common along the coast {A. Abercrombie,

 Abercrombie). 



Evidently a very abundant species, and in all probability 

 extending some way both North and South of Bombay. 

 The largest of the many specimens I have seen measures 

 35 millimetres longitudinally. It is a very uniform species 

 in all stages of its growth, and would appear to have been 

 confounded with M. hiculentiis (Reeve). Its nearest ally, 

 however, would seem to be AT. cristatiis (Brocchi) from the 

 Mediterranean, from which, however, it is quite distinct. 

 Some specimens are pale yellow, with faint brown transverse 

 fasciae. 



Pleurotoma (Clavus) PR-«CLARA, sp. nov. (PI. I, f 2).
