rrot, Liiiken 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.

 Ihering. 



IJi/la bwiftataj Blgr. 



A specimen of this species was among a collection made on 

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

HyJella Sumichrasti. 



Excrodonta Sumichrasti, BroccW, Bull. Soc. Pbilom. (7) iii. 1879, p. 20, 



and Miss. Sc. Mex., Batr. p. 48, pi. xv. fig. 2 (1882). 

 Hyldla 2)liitycephala, Cope, Proc. Am. Phil, Soc. xviii. 1879, p. 269. 



The above names apply to the same species and were 

 published in the same year. Brocchi's paper was read first 

 and apparently appeared before Cope's. 



DiagJena Jordani, Stejueger. 



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. Stejueger pro- 

 poses the new genus Tetroprion, allied to Triprion and 

 Diaglena^ differing from all others in the simultaneous 

 presence of vomerine and palatine teeth. Triprion spatulatuSj 

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

 no. ^2, 1887, p. 12), was described by Giinther (Ann. & Mag. 

 Nat. Plist. 5, X. 1882, p. 279) from living specimens ; the 

 dentition was therefore not examined. I may now state that 

 it has the palatine teeth situated as in Tetraprion Jordani, 

 which, in the absence of any other character of generic 

 importance, should stand as Diaglena Jordani.
