Hyla regilla Baird and 

 Girard. 



Range: Vancouver Island

 Lower California; east to 

 Idaho, Utah, Nevada and 

 Arizona. 



Habitat: On the ground, 

 especially about streams, 

 springs, ponds, swamps, and 

 other moist places. 



Size: Adults, 1-1 7/8 

 inches. (Males, 25.5-48 mm. 

 Females, 25-47 mm.). 



General appearance: This 

 small, delicate tree toad is 

 somewhat smaller and more 

 slender than the canyon tree 

 toad, {Hyla arenicolor) which 

 like this form has the rear 

 of the thighs uniform, not 

 spotted. This species reminds 

 the authors of species of 

 Pseudacris. The disks on the 

 fingers and toes are larger, 

 however. It is very variable 

 in color, usually with stripes 

 on the back and a triangle 

 between the eyes, and also 

 with a stripe along the side of 

 the head. 



One male is light brown in 

 color with a dark brown V 

 between the eyes and two 

 rows of large dark spots on 

 the back. It has a conspicu- 

 ous greenish black line from
