B. BELANGERI, Kiener. PI. 6, figs. 94, 95. 



Whorls smooth, polished, with distant revolving grooves which 

 are most apparent at the suture, and base of the body whorl ; 

 yellowish, with waved longitudinal faint chestnut lines. 



Length, '9-1 '4 inches. 



Aracan. Ceylon. 



P>. polita, Desh. (fig. 95), is this species, figured from a laded 

 specimen. 



B. DILUTA, Krauss. PL 6, figs. 96, 97. 



Whorls with revolving stria 1 ; whitish, lower part of body 

 whorl longitudinally flamed with chestnut-brown ; columella 



truncate at base. Length, 1 inch. 



Natal, So. Africa. 



Painted like B. semifiammea, Reeve, but immediately disting- 

 uished from that species by its narrow Tere&ra-like form and 

 truncate columella. This last character suggests the succeeding 

 species which, however, is peculiar in having a thickened lip, 

 minutely dentate within. It is possible that they are identical, 

 and that B. dilata has a thin, unarmed lip because the specimens 

 are not adult. Yon Martens has described a var. mediol&vix 

 (fig. 97), in which the revolving grooves do not occur on the 

 middle of the body whorl a character of no importance. 



Submenus Adinus, II. a id A. Adam?. 



B. TRUNCATA, Reeve. PI. 6, fig. 98. 



Yellowish white; whorls striated above and at base. 



Length, 1*25-1*5 inches. 



Habitat unknown. 



The characters of this species are those of the subgenus. It 

 is probably So. African. See remarks under preceding species. 



Unidentified and Doubtful Species.
