Hah. — Spencer's and St. Vincent's Gulfs (Adcock). 



This little shell is very dark brown, relieved by a pale zone between 

 two white keels, crossed by dark-brown streaks. The transverse lirae 

 are pretty prominent, and the whole surface is roughened by minute 

 laminoe. Another specimen sent me by Mr. Adcock is almost entirely 

 white.

 longitudinaliter sculpti ; anfractus ultimus spiram brevier, ad basim 

 contractus, brevissime rostratus ; columella parum contorta ; apertura

This little shell bears rather a curious resemblance to the British 

 B. teres. I have only seen three specimens, the type here described 

 being the largest ; the two smaller ones are shorter in proportion, and 

 not so concave at the top of the whorls. 



Yar. fusca. — A dark-brown variety, represented by a single specimen 

 in Mr. Adcock' s collection.

Hah. — Backstairs Passage, 6-20 fathoms. 



A thin, delicately sculptured shell, of which the ribs are of an

 spiral Krai are narrow and close, and crossed by extremely delicate 

 and profuse oblique laminae. The type specimen, besides the irregular 

 light-brown markings, has two narrow zones below the periphery ; 

 while others are pale straw-colour, without markings. All the
