" This species is not ailiued to any known form. It is perliaps 

 nearer to the little group to which A. graphicas belongs than to 

 any other, but it has not the short sutural tube nor the ovately 

 <:onoid form which characterizes that section of the genus. The 

 shortness of the constriction, and tiie very slight d.^gree in which 

 it expands towards the aperture, connect this form somewliat with 

 the section Dioryx of Mr. Benson." {Blaaford.)
