Muzzle oval, vertically truncate at the end and elevated ; canthus ros- 
trales obtuse, loreal region little oblique ; nares terminal. Membranum 
tympani distinct, round, its diameter one-third that of the eye-slit. Wrist 
extending to muzzle, and the heel to the middle of the orbit. Two large 
palmar tubercles. Cuneiform tubercles of sole prominent, not sheathed 
with horn, the outer solar tubercle not prominent; no proximal tarsal 
tubercle. Tarsus short; remainder of foot longer than tibia. Skin with 
low warts on all the upper surfaces of the head and body ; inguinal gland 
moderate, oval. Posterior inferior femoral region areolate. 
The vomerine teeth are in small fasiculi extending backwards from the 
line of the anterior margins of the choanre. The latter are twice as large as 
the small ostiapharyngea. The tongue is a wide oval, has a slit-like notch 
behind and is one-half free. 
Color above gray leaden, with indistinct darker plumbeous spots, of 
which the largest is between the orbits. There are three wide vertical 
dark gray bands at the upper lip, the last one on the tympanum, and two 
paler similar bands between them. Numerous black spots on the groin ; a 
black crescent on the inguinal gland. Limbs dark cross-banded above ; 
posterior face of femur darkly gray spotted. Lower surfaces dirty white;

No. 137, from Juiiaca at 12,550 feet. 
26. Buro cHILENSIS Tschudi, Batr. 88. Dum. Bibr. VIII, 678. B. spinu- 
losus Weigm. 
Nos. 2 and 4, Pacasmayo on the coast; 47, Arequipa, 7,500 feet ; 52, 
Chimbote Valley ; 54-56 and 124-126, Urubamba, Eastern Peru, 10,000 
feet ; 78-9, Cuzco, 11,000 feet ; 87-8, Yaurisque, East of Cuzco, on the 
Apurimac, 10,500 feet ; 102-110, Tinta, 11,000 feet; 129-135, Juliaca, 
12,550 feet. 
Having arranged the above thirty-six specimens of this toad in the order 
of the elevation above the sea at which they were found, beginning at the 
coast, and rising to 12,550 feet, I have discovered no characters of surface, of 
color, or of any other kind which are related to the habitats. Two of the 
three specimens from Pacasmayo, ¢‘ and Q, are twice the average size of 
the others ; the third one is as large as the largest of the others. Several 
specimens have spinulose warts.
