They form several rows on the back and exter- nal face of the tibia. At all other points the skin is closely areolated, the areolae 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. lentiginosus, though not relatively 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 j)romineut, and has an extensive acute edge; the external is much smaller, but it also has a free cutting edge transverse to the length of the 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 j'ellowish 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 arc 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 forma more or less reticulate pattern. 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; throat Fig. 66. Bu/o hemiophrys. No. 11927. Northern Montana ; \. Measurements of No. ll'J'27. M. Length of head and body 0
