HYLA BISTINCTA Cope 



1877. Hyla histincta Cope, Proc. Amer. Philos. Soc, vol. 17, no. 100, p. 87, July 

 20. — GtJNTHER, 1901, Biologia Centrali- Americana, Reptilia and Batrachia, 

 p. 265, June. — Nieden, 1923, Das Tierreich, Lief. 46, Amphibia, Anura I, 

 pp. 192, 247. 



Type locality. — "Most probably" Vera Cruz, Mexico. 



Range. — Unknown. 



Remarks. — The type of this species (U.S.N.M. No. 32361) seems 

 to be a male in breeding condition, inasmuch as the thumb has two 

 corneous callosities on its inner surface; the distal callosity is no 

 larger than the apical disk, but the proximal one is enormously en- 

 larged and forms a conspicuous prominence on the metacarpal. 

 These callosities are covered with closely spaced horny points. 

 According to Cope, this specimen was collected by Francis Sumichrast 

 along with the types of H. spilomma and of H. miotympanum. Sumi- 

 chrast spent some time at a hacienda near Cordoba in Vera Cruz, 

 and it is possible that the typQ of histincta was collected in this region. 

 The measurements of the type are as follows : Head-and-body length, 

 43.5 mm.; transverse diameter of tympanum, 1.7 mm.; transverse 

 diameter of eye, 5.1 mm.; anterior edge of eye to nostril, 3.7 mm.; 

 width of head at level of posterior angles of jaws, 14.4 mm. 



The diagnoses of Hyla histincta and H. taeniopus show how closely 

 these two tree frogs resemble each other. On both of them the sides 

 have a network of dark streaks or of blotches superimposed over the 

 yellow ground color. The fact that the upperparts (in alcohol) are
