toes are all aoproased, rather sharp alonff the edges, slender, with par 

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

 pallets, bnt little if any wider than the fingers, and very faint traees 

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

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

 their bases very slightly webbed, tiie nuMnl)rane tilling np the spaces 

 between the metatarsals of the two onter toes. The tnbercle at the 

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

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

 bric nine, in addition to the coccyx. 



Tiie entire body is stron ,\v 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, excei)t perhaps t])e sides of the head. The upper and under faces 

 of the thighs are also similarly granulated. 



In the males the up|)er parts are i)urplish-l)rown (greenish-brown 

 in life) with dark slate brown markings; beneath cream <Mlor. Tliere 

 is a triangular patch between the eyes, the base exti'uding 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 Oiirk pat(!h 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 delined. The extreme margin of the upper 

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

 narrow line of yellowish-white, w'licli widens after passing below the 

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

 of the under i)arts, 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 co'or then'. On each si(h' of the bac^k extends 

 a distinct stripe. IVom lu'ar the tymjianum to about o|)posite the ter- 

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

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

 stripes !' .irly parallel, though with a tendency in the outer ones to 

 diverge i>o.-.teriorIy. These stripes are sometimes irreguhir in outline, 

 the central one sometimes broken up into blotches, the «'xterior ones 

 less fre(iuently. Sometinu's scattered blotches are seen between the 

 Stripes. The upper surfaces of tiielimbsare indistinctly bande«l trans- 

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

 buttocks are brown, with (nrcular whitish spots on th" apices of the 

 granulation. The inner faces of the limbs are nn(H)l(U'e<l. 



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

 color above is fawn, sonu^times light bluish-gray ; and, as already re- 

 marked, the longitudinal stripes are occasionally broken up into coarse
