Western Chorus Frog. 



Pseudacris occidentalis (Baird and Girard). 



Remarks: This form as Litoria occidentalis was first described by 

 Baird and Girard in "A List of Reptiles Collected in California by 

 Dr. John L. LeConte." We prefer to believe it was collected in Cali- 

 fornia and that the name should not be assigned to a form of Texas 

 or of the Southeast. All the other batrachians of the report were 

 strictly western forms. Baird and Girard report Hyla re gill a in this 

 same paper, p. 301 , first describe it in another place of this same volume 

 (p. 174), and Hallowell also describes Hyla regilla in the same volume 

 (p. 183) as Hyla Scapularis. Nevertheless, the Litoria occidentalis of 

 this report might well be another variant specimen of the very vari- 

 able Hyla regilla. At that period we have Hallowell in one paper 

 (1854, pp. 96-97) describing Hyla regilla three times under three 

 different names. We therefore suspect Litoria occidentalis of being a 

 synonym of a western Hyla presumably Hyla regilla. A glance at the 

 plate of the Hyla regilla will show at once how many resemblances 

 this species has to Pseudacris. 



Possibly some day it may result that what we have called Pseuda- 

 cris nigrita clarkii from southern Texas to Kansas and what others 

 have called Pseudacris occidentalis from northern Texas to Kansas 

 may all be termed Pseudacris nigrita occidentalis or else Pseudacris 

 nigrita clarkii or each may be reduced to the synonymy of Pseudacris 

 nigrita triseriata.
