glaDcl a narrow oval. Dermal tubercles distinguished by their sm.ill 

 size and prominence. They form several rows on the back and exter- 

 nal face of the tibia. At all other points the skin is closely areolated, 

 the afeohie frequently acutely prominent, especially on the superior 

 face of the tibia and on the sides. The heel of the extended hind leg 

 reaches to the posterior border of the orbit. The posterior foot is wider 

 than in the B. lentiglnosiis, though not relativelj^ shorter. The web is 

 excavated to the line of the middle of the fourth (first) phalange. The 

 metatarsal tubercles are especially large. The internal is very wide and 

 I)rominent, and has an extensive acute edge; the external is much 

 smaller, but it also has a free cutting edge transverse to the length of 

 tlie tarsus. The length of the head to the position of the postorbital 

 crests enters the total (to the vent) four and a half times. 



The color is brown, marked on the back with a median yellowish 

 line, and two or three rows of brown spots of median size on each side 

 of it. These spots have one or two tubercles for their center pieces, 

 which are more reddish than the rest of the spot. There are two brown 

 spots on the upper lip and one below the tympanum. A large spot ex- 

 tends from below the parotoid gland to near the front of the humerus. 

 Posterior to this, with a light interval, there extends a longitudinal 

 deep brown band, which extends, with interruptions, to the groin. Be- 

 low this on the sides are other dark browu bands, which form a more or 

 less reticulate x>attern. The limbs and posterior feet have dark brown 

 cross-bands, and there is a very coarse dark brown reticulation of 

 brown or brownish-yellow on the posterior face of the femur. The belly 

 is more or less black spotted 5 throat immaculate.
