There are more rows of bristles than in B. heterotrichus, and the 

 shell is more globose with shorter spire and fewer whorls ; it is also 

 less solid. In B. scobinatus the spire is much longer and the aper- 

 ture proportionally smaller. The animal is dark with a tint of 

 rose. The measurements last given above are from Moricand.

Pfeiffer, who probably had not seen the shell, supposes this may 

 be the young of B. velutinohispidus. It is known to me by Mori- 

 cand's description and figures only. 



B. SCOBINATUS (Wood). PL 13, figs. 4, 7, 21 ; pi. 15, fig. 25. 



Shell narrowly umbilicate, ovate-conic, rather thin; olive yellow 

 or light brown-olive, somewhat shining. Surface with close, fine 

 spiral lines of short cuticular hairs or asperities, and spaced series 

 of much larger stiff short bristles. Spire long, conic, the apex ob- 

 tuse, 2 nepionic whorls sculptured with excessively close, minute,
