Sliell light and thin, ovate, acuminate above, clothed with a 

 thin, yellovrish olive epidermis, beneath which it is dirty or bluish- 

 white, striped a little obliquely with narrow and slightly wavy 

 reddish-brown streaks; suture almost horizontal, rather deep owing 

 to the rotundity of the volutions; whorls y^o very convex, the four 

 apical ones pale without stripes, all granulated, the granules on 

 upper ones which constitute the spire rather coarse in close spiral 

 series, the upper part of the body-whorl similarly granulated, the 

 lower portion much more finely, the line of demarcation between 

 the two kinds of granulation sudden and distinct. l"he mouth 

 rather small, very irregularly oval, occupying a little more than half 

 the entire length of the shell, dirty-vdiite or bluish-white within, 

 displaying the exterior reddish-brown striping; columella arched in 

 the middle, tortuous below and abruptly truncated at the base, of 

 a dirty white color and covered with a very thin callous, which 

 extends over the whorl and joins the lip at its upper extremity. 



This interesting species must not be mistaken for the young 

 of A. Wehvifsclii Morelet, to wliich it bears some resemblance. 



There are two specimens of it and apparently not quite adult. 

 I imagine, however, that they vrould not grov,- much larger but no 

 doubt would become somevdiat more solid.
