1 From an examination of specimens sent to the U. S. National Museum by Mr. 

 Wright I referred this to U. buckleyi, iu Pr. U. S. Nat. Mus., XV, p. 417. The type is 

 now in the U. S. National Museum, and I believe it to be a rather compressed, 

 bright young U.jayensis. 



2 A form of coruxcus a little less solid and inflated than the type, and quite brilliant. 

 3 This name occurs in B. II. Wright's Check List, but the species was not described 



until 1897. It scarcely differs from U. fryanus.
