whether Euonyma can stand. As at present constituted, it 

 very possibly con)j)rise3 representatives of three different 

 genera; but, for reasons previously mentioned, 1 adhere to 

 Pilsbiy's ariangement 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 

 averajre size.
