Inhabits the coasts of Tranquebar, Ceylon, and Nicobar Islands. 

 Chemnitz. 



Shell three-quarters of an inch or an inch long, and about 

 equally broad, glossy, and white, tessellated with distant 

 black spots ; the transverse ribs are alternately large and 

 small, and crenulated by longitudinal striae which pass over 

 them ; the outer margin of the outer lip is crenulated, and 

 the inner margin toothed ; the inner lip is plaited above and 

 tuberculated below. Chemnitz has quoted the above-men- 

 tioned shell of Favanne's for N. Exuvia, but it undoubtedly 

 belongs to the present species, and La Grande Grive orien- 

 tale (Favanne, ii. p. 201.), may probably be a large Variety 

 of the same ; but the figure, which is a copy from Argen- 

 ville's t. 7- f. B, badly accords with the description. 



HiSTRio. 48. Shell with unequal transverse ribs; 

 outer lip crenated on the inner margin, and 

 the inner lip four-toothed.

Inhabits the East Indian Seas. Chemnitz. 



Linnaeus for N. Histrio has only quoted Rumphius, t. 22. f. 6, 

 which badly accords with his description, and is much more 

 like N. Larva. The shell which Chemnitz has figured ap- 

 pears to be about an inch and a quarter long, and nearly 

 equally broad, and variously mottled or somewhat tessellated 

 with black and white ; the pillar-lip is nearly smooth, yel- 

 lowish, and the margin has four strong teeth. Chemnitz 

 has quoted La Jonquille of Favanne, but Argenville, t. 7, 

 f. I, of which Favanne's figure is a copy, has been quoted
