Inhabits the East Indies. Bruginere. 



Bruguiere has described this shell to be two inches long and 

 ten lines broad, of a blackish colour below, which changes 

 gradually to yellowish brown at the summit ; he says it is 

 distinguishable by a large compressed tuberculated belt at 

 the sutures, besides which each whirl of the spire has two 

 transverse granulated ribs, and on the body-whirl these ribs 

 are more numerous. 1 never saw a specimen of the shell, 

 which is said to have been * found by Mr, Bryer, near Wey- 

 mouth, after a violent storm in 1795,' but from the descrip- 

 tion, I think it is more likely to belong to the present species 

 than to the Linnaean M. fuscatus. 



SERRATUS. 154. Shell turreted, with longitudinal 

 striae, and two transverse serrated ribs, of 

 which the upper is largest, serratures spinous 

 and compressed.

Inhabits the coasts of the Friendly Islands, and is found fossil 

 in France. Bruguiere. 



Shell about two inches and a quarter long, and hardly one-third 

 as broad, and is white without any coloured markings ; the 

 spire consists of about fifteen whirls, with fine longitudinal 

 strise, and two transverse ribs armed with pointed leeth, of 

 which the lower rib is much smaller than the other ; the 

 body-whirl has four of these ribs, and they form corres- 

 ponding grooves within the aperture. 



ASPER. 155. Shell turreted, with longitudinal 

 plaited mviricated ribs, and transverse striae ; 

 pillar with one plait, and the beak ascending.
