vocal sac apparent in the males; interorbital space only slightly 

 greater than internasal space; first and second fingers equal; not as 

 heavily pigmented as B. boreas boreas. 



Voice: Its song is a slow deep-toned prolonged trill. 'The droning 

 call of B. woodhousii is hard to tell from that of B. fow/eri> at least 

 when one hears them apart, as he must in the field. On the other 

 hand, B. americanus and B. calijornicus are much alike and the 

 rattling call of B. cognatus very different. B. halophilus, on the other 

 hand, has no call to speak of. It is the quietest Bufo I know." (Letter 

 of G. S. Myers, April 9, 1933). 



Breeding: They breed from January to July, according to the 

 climate of location. The eggs are in long strings laid at the margins of 

 ponds or at edges of flowing streams and are occasionally in two or 

 three rows. There are no partitions between the eggs. The vitellus is 

 1/16 inch (1.7 mm.), the outer tube 1/5 inch (5 mm.), the inner 

 tube 1/7 inch (3.6 mm.). The dull blackish medium tadpoles are 

 2 1/5 inches (55 mm.). The tooth ridges are 2/3. After a tadpole period 

 of 28 to 45 days, they transform from April to August at 1/2 inch 

 (12 mm.). 



Notes: "The California toad is such a heavy-bodied animal that 

 it seldom hops in t^he conventional manner. . . . When not frightened 

 it walks in slow fashion dragging the hind feet so that toes are con- 

 tinually in contact with the ground." (Grinnell and Storer, 1924, p. 

 636).
