Hab., Mekran coast, Charbar, 5 fathoms, mud bottom ; and Gulf 

 of Oman, lat. 24^ 58' N., long. 54" 56' E., 156 fathoms. 



A large and two small examples, of which the former is taken as the 

 type. The lamellae, irregular, thin, and remarkably shallow, seem 

 characteristic, and also the spiral striae, partially covering the surface 

 of the last three whorls. The spiral rib, at the base of the body whorl, 

 is well defined and conspicuous. The colour is peculiar, of a livid- 

 brown; surface fairly smooth and shining. S. funicuJata Watson, from 

 Pernambuco, is probably akin.
