By Edward H. Taylor 



The two species of frogs described lierein are a part of the collection 

 made by Dr. Hobart M. Smith in Mexico dming 1938 and 1939 for 

 the United States National Aluseum. These novelties were called 

 to my attention by Dr. Smith, who requested that I describe the 

 forms. The drawings of the types were made by Walter Yost; those 

 of the tadpole of the Hyla by Hazel Watson.
