 Grande) .—Cope, 1887, U. S. Nat. Mus. Bull. 32, p. 16. 



Type locality. — Mexico. 



Range. — Exact limits of range unknown; probably occurs on the 

 Mexican Plateau from southern Tamaulipas to Puebla. 



Remarks. — Under the caption for the explanation of the plate with 

 the original illustration of this frog, Baird simply stated that it was 

 collected in Mexico. The original drawing of the type, which was 

 used by Professor Baird in his report on the reptiles of the United 

 States and Mexican Boundary Survey, was made by J. H. Kichard 

 and is dated 1856. At the right lower margin, "City of Mexico" is 

 written in pencil and on the left lower margin "Batrachyla." In 

 1875, Cope gave "Lower Rio Grande" as the locahty, but in 1887 he 

 stated that the type was taken 40 leagues north of the City of Mexico 

 and that it bore the number 3207 in the collection of the National 

 Museum. An unlocated specimen from Camp Yuma, Calif., col- 

 lected by Dr. R. O. Abbott, bears this number in the catalogue with 

 the original entries. A missing "Hyla" collected by John Potts "40 

 leagues S. of City of Mex.," and catalogued under the number 3237, 

 may be the original entry for the type of Bairachyla longipes. The 

 type is now lost. 



Specimens examined.— One (M.C.Z. No. 9308), collected at Miqui- 

 huana, 80 miles southwest of Victoria, Tamaulipas, in 1922 by W. 

 W. Brown.
