Tlie upper parts ^I'liejall.v aro sinodtli, tlici sidos apparcntlj' soino- 

 vliar (Mirrugati'd (sciirccly pustular), tlnaijjli liow iiiucli is owiiij^f to tlio 

 iili'dliol (tail not !)(' easily (IctciriiintMl. The po.stcrioi', inferior, and su- 

 perior faces of the thiylis are j,'raiiulated; tliis, however, not exteudinjf 

 to the body, wiiicii is iufeiiorly entirely smooth. A rather l)road but 

 low fold of skin may be tra(;ed from above the tym])ainim along the 

 hack nearly to the thigh. A small ridge behind the tymi»anuni. 



Thtnnner toe does not reaeh much beyond the middle of tho meta- 

 tarsal of the fourth. Tho web is but sliglitly developed; it extends 

 fully only from the penultimate articulation of the outer to the ante- 

 lienidtimate of the fourth toe; from this to the pciuultimate of the 

 third; from the niid<lleof the tliii'd phalange of this (counting from ti[)) 

 to the se(!ond articulation of .second ; fiom third Joint of second to flrst 

 joint of fifth; in each ease extending a little beyond as a narrow mar- 

 ginal niend)rane. The terndnal two and one liaif phalanges of tbo 

 longest toe, however, are almost entirely free, and one and one half of 

 the rest. Tho membrane is more cut out on the inner edges of the 

 joints than the outer, by nearly one phalange. The cuneiform bone is 

 slightly developed. No tubercle (»i)posite on the outer edge of sole. 



Upper parts lirownish-olive, minutely and obsoK'tely mottled with 

 lighter. The entire upper i)arts and sides are covered by a number of 

 dark brown blotches, with light yellowish center; they are subcircular, 

 and smaller than tho tympanum. They are most distinct and crowded 

 anteriorly, and do not invade the outer ridges of skin. The ground- 

 color of the ui)per surface of the fore limbs and the sides of the head 

 is yellowish brown, with vermiculation of brown, as also some distinct 

 blotchesof the same on the former. The hind legs have numerous par- 

 allel and transverse dark brown bars, three or four on the thighs, four or 

 livoon the tibia, three ()n the tarsus, and several om the edge of the loot. 

 These bars are broader than their interspaces, and are margined by a 

 narrow yellowish line, so that the interval between two adjacent light 

 lines exhibits a brown ground lighter than the dark bars just described, 

 and also transverse. Indeed, they may be described as narrower bars of 

 lighter tint between the dark bais, parallel to them, and «ei)arated by 

 narrow yellowish-Rrown lines. Tlie lower parts are yellowish-white, 

 unspotted, including the interior and inferior surfaces of the limbs. A 

 few scattered blotches are .seen on the throat and chin. The buttocks 

 are yellowish white, witii a few ol)solete dark blotches, smallest on tho 

 posterior eilge. The central third of the tyiui)anuni is white.
