outer lip with the outer margin crenated, and the inner mar- 

 gin has eight teeth, of which those at each extremity are 

 largest ; the inner hp is somewhat convex, wrinkled and tu- 

 berculated; and has three or four strong teeth on the margin. 

 It appears to be nearly allied to N.grossa, but has the spire 

 very obtuse.

 Shell an inch long and about equally broad, with thirteen or 

 fourteen somewhat spotted brown transverse ribs, and the 

 interstices white ; the outer lip has its outer margin crenated, 

 and on the inner margin there is a strong tooth at each ex- 

 tremity, with intermediate crenatures ; the inner lip is 

 wrinkled, tinged with yellow, and three-toothed. Linnzeus 

 has described this species * spira acuta,' and the shell which 

 Born has figured under the name of N. grossa differs in 

 being obtuse, and therefore answers better to the foregoing 

 species. 



chama:leon. 57. Shell sub-globular, with about 

 twenty transverse ribs, and the spire obtuse ; 

 lips toothed, and the inner one wrinkled and 

 tuberculated.
