truncated end of the columella. The a})erture is about as long 

 as half the entire length of the shell, of an irregular, elongate, 

 oval form, acute superiorly, very white within, being covered with 

 a thick, shelly deposit of that Irae. The columella is only slightly 

 arched, also clothed with a white callosity extending upwards over 

 the whorl as far as the extremity of the outer lip. Its truncation 

 is rather abrupt and narrow. 



The nearest ally of this species appears to be A. Kraussi, 

 Rve. It differs from it, however, in ha\ing a more elongate and 

 acuminate spire, the more varied and irregular character of the 

 blotching and the strongly marked granular sculpture.

Shell rather solid and heavy for its size, ovate, white, varied 

 with numerous close-set and slightly oblique reddish-brown stripes, 

 which are rather regular and only slightly undulating; spire 

 obtusely conical, white towards the apex which is rather rounded 

 and not acute; suture but slightly obUque, crenulated; whorls 7

 with a close granulation, the granules being elongate; on the two 

 succeeding whorls they are less conspicuous, and on the last
