Bufo beldingi, sp. uov. 



Description. — Head broader than long, muzzle acuminate and pro- 

 jecting. Cauthus rostralis indetinite. Superciliary ridges small. Ver- 

 tical gutter broad and small. Eyes very small, almost concealed by 

 heavy overhanging lids whicli are densely tuberculated. Tympanum 

 very small, one-half the size of parotid, which is subcircular and tuber- 

 culated. Skin smooth excej^t on flanks. Toes a little more than two- 

 thirds webbed, shovel very small and light colored. Two carpal tuber- 

 cles, external large, both oval; one small rounded tubercle. Color in 

 old specimens, bluish gray, darker on sides, with orange-colored tuber- 

 cles. Legs banded with same color as on sides. Belly yellowish wliite, 

 with bluish spots near insertion of both arms. In young specimens the 

 color of the back is yellowish gray, tlie sides being darker, the tuber- 

 cles being bright orange. Resembles somewhat Bufo microscaphus, in 

 general outline, but the coloration is very different. ^Named in honor 

 or Mr. L. Belding, the collector of the specimen. 



Crotaphytus copeii, sp. no v. 



Description.— Head broader and longer than C. wisUzenl. Super- 

 ciliary ridges well developed. Anterior border of auditory aperture 

 with one, two, or three larger scales than the surrounding ones. Scales 

 anterior to orbits, and posterior to nostrils, on upper surface of head, 

 larger than elsewhere. Scales on gular fold larger than those anteriorly 

 or posteriorly. Upper and lower labials fifteen each to angle near base 

 of jaw. Infraorbital chain consists of four i)lates, the second very large. 

 Femoral pores large and distinct. First phalanx of hind leg extended

 circular spots, each having a lighter center. Anterior to the lower 

 extremities the spots become rhomboid in shape, ami on the tail are

 which it differs in certain particulars, the coloration being entirely dif- 

 ferent from any of the known species of Crotaphytus.
