rotoid. There is a green band along the side. These green spots are 

 partially outlined with black on the green and cream on the outer 

 edges. The under parts are light, including the throat. In these males, 

 the light throat extends back as a flap over the thin, dark colored skin 

 of the lower throat which extends forward when inflated. In another 

 toad, the green spots are more broken up, and the green band on the 

 side becomes broken into spots. The head is broad, the snout short. 

 The sides and front of the snout are steep. The hands and feet are 

 light with dark tips. The conspicuous mark of this form is the large 

 boss covering the prefrontal region from the anterior 1/3 of the orbit 

 to the nostril. Extending backward from this are the two broad 

 superciliary ridges forming an open angle. 



Structure: Head broad; snout short; sides and front of snout 

 steep; boss conspicuous, ridges divaricating at rear; parotoid glands 

 small, elevated, widely separated, oval in shape extending obliquely 

 downward; two metatarsal tubercles with free cutting dark edge; hind 

 leg approximates body length; hind foot long in proportion to hind 

 leg; interorbital space narrow; internasal space greater than inter- 

 orbital; snout only equal to or less than eye; toes webbed, webs 

 deeply indented; nostrils set far apart; femur short; horny excres- 

 cences on back of first finger of male, and to less degree or lacking 

 on the second finger. 



Voice: The vocal sac of the male is a large "sausage" extending out 

 and upward. Deflated, the thin discolored skin is closely folded under 

 an apron-like extension of light colored pebbly skin of the throat. It 

 is at the rear of the throat and the 'apron' may hang down over the 

 forebreast as much as 15 mm. The call is made up of harsh low pitched 

 notes, "harsh, chattering call." (Klauber). 



Breeding: They breed from April to September, dependent upon 

 rainfall; in the northern states of their range, from May to July. 

 Little is known about the eggs and tadpoles. 



Notes: July 8, 1917. We found a large stream rushing through 

 Sierra Blanca, Texas. They had not had rain for six months. The flat 

 land was overflowed and a swift current went under the small bridge. 

 At seven o'clock, while it was still day, we heard no notes in the creek, 

 but later when we were camped one half mile away, we heard the 

 chorus plainly and decided it must be spadefoots. . . . We found 

 three species of toads and two of spadefoots migrating from the 

 mountain sides of Sierra Blanca downward toward the pool and 

 noise. The boys, at night, captured B. woodhousii, B. cognatus and 

 B. compacti/is on the hillside and in the stream.
