From Bufo lentiginosus woodhousii, of the Lower Colorado River 

 district and farther east, the new toad differs decidedly in its smaller 

 size, short hind legs, divergent cranial crests, and in the presence of 

 a bony nasal elevation. 



Description of type. — Size medium; hind legs very short, femur 

 almost entirely enclosed in skin of abdomen; head short and thick; 

 nasal region elevated into a bony protuberance; longitudinal cranial 

 crests more or less united across median region, and slightly divergent ; 

 transverse crests divided by width of median groove; parotoids oval, 

 slightly divergent and very broad; inner tubercle of hind foot with 

 a sharp edge ; outer tubercle very small, rounded and without cutting 

 edge; eyelids and back evenly tuberculated ; tympanum oval, shorter 

 than diameter of eye; a dozen or more large whitish tubercles below 

 and just posterior to the tympanum. The color when taken was 

 light olive-green above, with two light patches about six millimeters 

 in diameter immediately behind the parotoids. Upper lip below the 

 eye barred vertically with paler tone; light areas present on eyelids 

 and anterior ends of parotoids. No vertebral stripe present; under- 

 parts creamy white, unspotted. Bases of several of the tubercules on 

 the back encircled by small black rings, and no large greenish spots 

 in the dorsal coloration. 



Distribution. — The type was found on a lawn in the middle of 

 town, about eight o'clock in the evening. The Santa Paula district 

 is about sixty miles east of the San Fernando Valley (where the other 

 specimen of this subspecies was found), and a mountain spur about 

 one thousand feet in elevation separates the two localities of capture. 

 Both localities lie within the San Diegan faunal area in the Lower 

 Sonoran life-zone, as the latter has been delimited in California. 

 Both localities are of semi-arid character, and the streams are inter- 

 mittent in the arroyos near which each of these toads was captured.
