Major M. Connolly on 



whether Euonyma can stand. As at present constituted, it 

 very possibly comprises representatives of three different 

 genera; but, for reasons previously mentioned, I adhere to 

 Pilsbry's anangement of the genus, and at the same time 

 place therein, provisionally, several forms hitherto un- 

 described, which, though nearly allied to Opeas, exceed it in 

 average size.

As the proper understanding of this species and its distri- 

 bution is of importance, I append in tabular form (a) Krauss'.s 

 description of the type and (b) Pfeiffer's of the shells in 

 Krauss's collection : —
