 ger. 



Range:" Sierra Tara-

 1919, P- 415). 



"On June 18, 1931, near 

 Pena Blanca Springs, Santa 

 Cruz County, x^rizona, the 

 writer was fortunate in find- 

 ing a colony of the Mexican 

 frog, Rana tarahumarae 

 Boulenger. A specimen for- 

 warded to the National Mu- 

 seum was kindly examined 

 by Dr. Remington Kellogg, 

 who pronounced it to be that 

 species. Previously, these 

 frogs were reported only from 

 the Tarahumara Mountains, 

 Chihuahua, Mexico. In Ari- 

 zona, they were found at an 

 elevation of approximately 

 4,000 feet in a locality only 

 two miles from the interna- 

 tional boundary." — (Berry 

 Campbell. 1931, p. 164). 



Habitat: "The colony was 

 clustered around a series of 

 pot-holes in a canyon, . . . 

 and no running water could 

 be found in the region. Besides 

 the twenty or so adults seen 

 in these pot-holes, a group of 

 probably half that number 

 was found in an old tumbled- 

 in mine which had filled 

 with water." — (Campbell, 

 p. 164).
