oblique, not much larger than the tympanum. Brown above, 

 with or without yellowish spots ; dirty white below, without 

 any spots. Male with a subgular vocal sac and the usual 

 copulatory asj^erities on the three inner fingers. 



From snout to vent 82 millim. 



Prof. Liitken has submitted to me three specimens obtained 

 by A. S. Oersted at Cartago, Costa Rica. One of these speci- 

 mens is now in the British Museum. 



Ilyla nana, Blgr. 



Has been received from E.io Grande do Sul through Dr. v. 

 Ihering.

A s[)ecimen of this species was among a collection made on 

 the Tibagy River, Province Parana, by Dr. G. F. Grillo, and

The above names apply to the same species and were 

 ])ublished in the same year. Brocchi's paper was read first 

 and apparently ap[)eared before Cope's. 



DiagJena Jordani, Stejneger. 



Vol. xiv., now in course of publication, of the * Proceedings 

 of the U.S. National Museum,' contains (p. 167, pi. iii.) the 

 description of a new tree-frog for which Mr. Stejneger pro- 

 poses the new genus Tetrapnon, allied to Triprion and 

 Dlaglena, differing from all others in the simultaneous 

 presence of vomerine and palatine teeth. Triprion spatidatu^, 

 the type of Cope's genus Diaglena (Bull. U. S. Nat. Mus. 

 no. '6'ly 1887, -p. 12), was described by Gunther (Ann. ^t Mag. 

 Nat. Hist. 5, X. 1882, p. 279) from living sj)ecimens ; the 

 dentition was therefore not examined. 1 may now state that 

 it has the palatine teeth situated as in Tetraprion Jord:ini, 

 which, in the absence of any other character of generic 

 importance, should stand as Diaylena Jordani.
