A REVIEW OF THE HERPETOLOGY OF LOWER 

 CALIFORNIA. PART II— BATRACHIANS. 



BY JOHN VAN DENBURGH, 

 Curator of the Department of Herpetology. 



The long peninsula of Lower California, parched and 

 barren except where some stream, escaping from the 

 sheltering shadows of the upland oaks and pines, winds 

 down to the ocean or sinks almost immediately into the 

 panting soil, has few attractions to offer the batrachia. 

 In consequence, few representatives of this class have been 

 found within its limits. Those that do occur either live 

 in the moister mountainous areas or are of wide distribu- 

 tion and comparatively great adaptation for life in a land 

 arid and desolate. The Bufo and the Scafhiofus range 

 as far east as Texas; the Batrachose^s and Hyla regilla 

 occupy a considerable area along the Pacific ; while the 

 Plethodon has been taken, elsewhere, only in southern 

 California.

I fail to find any constant difference between specimens 

 of this species from various parts of its range. The char- 

 acters which have been claimed to be distinctive seem to 

 be purely individual, and to occur wherever a series of 

 specimens has been secured.
