toes are all depressed, rather sharp along the edges, slender, with par 

 allel sides, and not fringed. All are terminated by slight knobs, not 

 pallets, but little if any wider than the lingers, and very faint traces 

 of the marginal nail lilie groove. The hands are not webbed, except a 

 very slight basal web between the three outer fingers. The toes have 

 their bases very slightly webbed, the membrane filling up the spaces 

 between the metatarsals of the two outer toes. The tubercle at the 

 base of the inner toe rather large; the one opposite at base of outer 

 toe, small. Prominent tubercles beneath all the articulations. Yerte- 

 brse nine, in addition to the coccyx. 



The entire body is strongly and coarsely granulated, conspicuously 

 below, where it extends over the chin, between the arms, and on the 

 arm nearly to the elbow joint; in fact, no part is free from the granula- 

 tion, except perhaps the sides of the head. The upper and under faces 

 of the thighs are also similarly granulated, 



In the males the upper parts are purplish-brown (greenish-brown 

 in life) with dark slate brown markings; beneath cream color. There 

 is a triangular patch between the eyes, the base extending directly 

 across, the apex pointing down the back, the sides concave. In front of 

 this, in the axis of the head and between the nostrils, is a small longi- 

 tudinal streak. A dark patch commences on the side of the snout and 

 extends backwards on the side of the head, including the tympanum, 

 and, widening on the sides, fades out near the groin ; the upper margin 

 of this is most distinctly defined. The extreme margin of the upper 

 jaw is dark mottled, but just above it and below the lateral vitta is a 

 narrow line of yellowish-white, which widens after passing below the 

 tympanum and, crossing above the shoulder, runs into the light color 

 of the under parts, completely isolating the fore-leg. In the male the 

 chin is mottled black ; and in all there is a narrow, indistinct streak of 

 brown extending from the lower jaw to the outer surface of the arm, con- 

 tinuous with the ground color there. On each side of the back extends 

 a distinct stripe, from near the tympanum to -about opposite the ter- 

 mination of the lateral stripes. An additional stripe is seen down the 

 middle of the back, scarcely commencing so far forward ; the three 

 stripes nearly parallel, though with a tendency in the outer ones to 

 diverge posteriorly. These stripes are sometimes irregular in outline, 

 the central one sometimes broken up into blotches, the exterior ones 

 less frequently. Sometimes scattered blotches are seen between the 

 stripes. The upper surfaces of the limbs are indistinctly banded trans- 

 versely, sometimes only blotched confusedly; the posterior faces of the 

 buttocks are brown, with circular whitish spots on the apices of the 

 granulation. The inner faces of the limbs are uncolored. 



In some specimens, which appear to be principally females, the ground 

 color above is fawn, sometimes light bluish-gray ; and, as already re- 

 marked, the longitudinal stripes are occasionally broken up into coarse
