This has a somewhat closer affinity with the two foUon-ing 



species than with the two which precede.

This is the type of the group, Sp. 355 to 358, which, as 

 before mentioned, I am inclined to think are but- one 

 species in dift'erent states. 



Species 359. (Mus. Cuming.)

 subcorned, late mnbilicatd, anfractibus sex, lavibus, 

 nitidiusculis, columella expanm, aperiiirn suborbicidari

 nidely elevately striated, columella reflected, some- 

 what twisted, lip simple, slightly expanded ; whitish, 

 stained with pale brownish ash-colour towards the 

 apex, and marked here and there with longitudinal 

 red lines. 

 For authority, locality, and remarks on this species see 

 PL XVII. Sp. 98, in which place a shell is represented 

 agreeing better with the B. Uthoicm of D'Orbigny.
