Type locality. — Near Jalapa and Mirador, State of Vera Cruz, 

 Mexico. 



Range. — From Orizaba in Vera Cruz and Necaxa in Puebla south- 

 west to Tehuantepec and Chiapas. 



Remarks. — Unfortunately one of the cotypes of Hyla miotympa- 

 num (U.S.N.M. No. 6311),fromnear Jalapa in Vera Cruz and collected 

 by R. Montes de Oca, is missing, and the other, a specimen from 

 Mirador collected by Dr. Carlos Sartorius, apparently was never 

 entered in the museum catalogue. 



Cope in 1877 pointed out that Peters's Hyla microtis was identical 

 with his H. mittympanum. The two cotypes of H. microtis (M.N.B. 

 No. 6657) were collected by Berkenbusch. These specimens are typical 

 individuals of H. miotympanum. A brief description of these cotypes 

 follows: Head-and-body length, respectively, 35.4 and 39 mm.; tym- 

 panum minute, the transverse diameter of one being 1.4 mm.; the 

 hind limb being carried forward along the body, the tibio-tarsal joint 

 reaches to between eye and tip of snout; skin of underparts areolate; 

 vent dark brown, with narrow white superior edge. 



The general similarity of Hyla godmani Giinther to Hyla miotym- 

 panum Cope became apparent when specimens of the latter were 

 compared with the description and figures of Giinther. This alloca-
