 Shell four or five inches long, and about an inch and three- 

 quarters broad, of a whitish colour, with dark brown trans- 

 verse striae, which are generally alternately larger ; the base 

 of the body-whirl is transversely ribbed and tuberculated, and 

 all the lower whirls have a row on their under halves of large 

 compressed somewhat pointed nodules ; the inside of the out- 

 er lip is strongly grooved, and the beak is much straighter 

 than in M. Aluco.

Inhabits the River Gambia, opposite the factory. Adanson. 



Shell about two inches long, and half as broad ; it is shorter and 

 proportionably broader than the preceding species, to which 

 it is very nearly allied, and with which it appears to have 

 been frequently confounded ; Adanson says that young shells 

 are white, and that with age they become spotted with brown, 



€LAVA. 145. Shell turreted, solid, with trans- 

 verse striae, and nodulous plaits above ; out- 

 er lip double, and the beak ascending.

This shell appears by the figures to be about six inches long, 

 and an inch and three-quarters broad, and is of a yellowish 

 colour somewhat tesselated with darker spots ; it has fifteen 

 or sixteen flattish whirls, with six or seven transverse narrow 

 grooves in each, and plaited at their upper extremities ; the 

 outer lip is not crenulated on the margin, but within it is 

 slightly grooved, and the beak is bent upward.?.
