I have never seen this species, but Fischer and Crosse give 

 a full description and beautiful figures of -it in the Mission 

 Scientifique. It is shorter in proportion to its height than A. 

 soleniforniis and differs from the other allied species in having 

 the anterior end shining.

The figured type is not in the Lea Collection, but two well 

 matched valves very closely approaching it are. The outline 

 is trapezoid, the shell being considerably narrowed in front. 

 It is not so inflated as // bamboiisearuyn, is narrower in front, 

 and the anterior part of the epidemiis is not smooth.
