MIJREX. 733 



•wards their upper margins, and crowned with undulated some- 

 what imbricated membranaceous scales, of which those on 

 the body-whirl are incurvated ; the colour is yellowish, with 

 two or three broad transverse more or less interrupted brown 

 bands. I never saw a specimen of this species, which is said 

 to be very rare, but it appears from the description to bear 

 some resemblance to Buccimim Betour. 



DOLARIUM. 103. Shell with remote, much elevat- 

 ed, obtuse, narrow belts, and smaller lonj^i- 

 tudiual plaits ; whirls flat above, and the sum- 

 mit obtuse.

Shell commonly about an inch and a half long, and an inch and 

 a quarter broad, of an uniform greyish brown or horn-co- 

 lour ; it has about six narrow much elevated obtuse belts on 

 the body-whirl, and two on the first whirl of the spire ; the 

 other whirls are much depressed, and form a rounded knob ; 

 the pillar is umbilicated, and the beak short. Some of its 

 synonyms have been confounded by almost every author with 

 those of M. cutaceus, from which it differs in having the 

 whirls more produced, and in the want of a longitudinal va- 

 rix. 



CORNEUS. 104. Shell oblong, with eight convex 

 whirls, striated transversely, and slightly 

 wrinkled longitudinally ; beak rather long, 

 and somewhat ascending.
