" Some of the peculiarities of this species, such as tlie 

 canalifulate base of the peristome, aud the two or three small 

 plaits en the constrictions are repeated in the next described 

 [A. 'polygonoma']. The plaits or ridges just referred to, although 

 they have corresponding internal hollows, are scarcely so promi- 

 nent as those forming the sculpture of the upper portion of the 

 shell. They are nearer to the mouth than to the rise of the 

 sutural tube, and rest upon a tumidity which is scarcely sufficiently 

 pronounced to enable the species to be assigned to the secriou 

 CTiarax of Benson, although it exactly represents the well-marketl 

 I'idge in the undermentioned species A. jwh/gonorna. The sutural 

 tube is, in one specimen, somewhat short of the typical length."
