Inhabits the coasts of the Nicobar Islands. Chemnitz. 



Shell about one inch and eight lines long, and thirteen lines 

 broad, and has the varices crenulated, and somewhat foliated 

 on their margins ; the colour is yellowish brown variegated 

 with white, and clouded or transversely striped with dark 

 brown ; the aperture and throat are white and shining. The 

 colour is however variable, according to Gmelin, who has 

 very strangely placed this species in the third division after 

 M. Anns, and also as a variety of M. Brandaris. 



MELANOMATHOS. 11. Shell sub-fusiform, trans- 

 versely striated, with eight spinous varices, 

 and the spines black ; spire nodulous and 

 prickly ; beak short and acute.

Inhabits the East Indian Seas. Chemnitz. 



Shell about an inch and a quarter long, and three-quarters of 

 an inch broad, white, with about eight blackish varices, 

 which are armed with crowded spines of the same colour. 

 Argenville's figure, from which the M. Radix of Gmelin 

 has been wholly constituted, appears to differ only in having 

 the varices somewhat furbelowed as well as spinous. 



** Foliated, and the Beak short. 



RAMosus. 12. Shell transversely grooved, and some- 

 what nodulous, with three foliated and 

 branched varices ; beak short and truncated.
