much evidence that Cope himself had examined it. In 1866, in 

 his Genera of the Arciferous Anura (Journ. Acad. Nat. Sci. 

 Phila., (2), 6, p. 96), he erected, in his key, a new genus, — 

 Epirexis, — using B. longipes as the type. Here he gives 

 only a few words of general description: "Muzzle and can- 

 thus rostralis contracted, little marked; vomerine teeth, digital 

 dilatations large." On page 90, however, he lists Epirexis 

 longipes as among the species of his clan Hylodes having certain 

 peculiarities of the dermal attachments. Again, on p. 92, it is 

 evidently included in his count of Mexican forms, for he speaks 

 of three having complete crania and one a bony style, — but 

 no actual mention is made here that he had the specimen in 

 hand, although it is strongly to be inferred. 



Epirexis longipes has, consequently, been no more than a 

 name these sixty years, and Boulenger made no effort to allo- 

 cate it in the Catalogue of the Salientia (1882). It was, there- 

 fore, a surprise recently to find a frog which at first sight I could 

 not identify but which later I noticed agreed remarkably with 

 the characters shown in Baird's figures, and I have now no 

 hesitation in believing that I have the same species before me. 

 It may be redescribed as follows: 



Elentherodactylus longipes (Baird) 



M. C. Z., no. 930S, from Miquihuana, eighty miles southwest of Victoria, 

 Tamaulipas, Mexico; W. W. Brown, collector. 



Tongue large, round, not emarginate behind; vomerine teeth in two 

 small round groups well behind and between the choanae, the groups well 

 separated from each other; nostril near tip of snout, separated from the 

 eye by a distance greater than that of the eye's diameter; discs of three 

 fingers large and rounded; the inner finger has the tip scarcely expanded 

 at all; discs of all the toes well developed and rounded; first toe not reach- 

 ing base of disc of second; subarticular tubercles well developed; meta- 

 tarsal tubercles rather small and flat; a short and feebly developed tarsal
