var. /3, and is stated to be of a brown colour, witb a tliinner shell. 

 The species differs from T. sulcipes principally by the narrower 

 whorls, but the shell is also more solid, the umbilicus is narrower, 

 the keel is sharper owing to the whorls being excavated above 

 and below, while the spiral striae are less numerous and more 

 indistinct.
