tbouyh not promiiieiit, but .siiiootlicd over. The buttocks are apiiar- 

 eiitly smoother thau common, the usual gnmnhitioii being scarcely 

 discernible. Tiie under parts are entirely smooth. 



The tinjirers are all free and of rather unusual length, and taper sud- 

 denly from the swollen base. The third is longest, the (Irt and fourtii 

 nearly equal, though the latter is rather longer. The fourth toe is loiij^ 

 est, fifth and third rather shorter. All the terminal phalanges are curved 

 downwards and taper to rather an acute tip; the web is more cut oui 

 on the inner edges of the toes than on the outer; on the latter it extends 

 to a little beyond the middle of the last phalange ; on the former scarcid.v 

 beyond the last Joint; itiseverywheredecidedly concave when stretched. 

 The cuneiform tubercle is small, and there is a slight membrane extend 

 ing from it along the inner edge of the foot. 



The general color above is of a purplish-brown, beneath grayish-white 

 or ash, everywhere minutely blotched or vermiculated with spots and 

 sinuations of lighter; sometimcvS more in irregular spots, sonu'times 

 more in vermiculations. Deneath, these light spots are obsolete towards 

 the chin, but they are very distinct on the side about the groin, and on 

 the thighs anteriorly, posteriorly, and interiorly, where they are larger 

 than their interspaces. In the typical and best specimen the ground- 

 color of the entire limbs is purplish-brown, rather lighter beneath and 

 internally, with the lighter spots scattered everywhere, and very obso- 

 lete indications of transverse bars above. This ai>pears to be a male. 



A fenuile still larger than the specimen upon which the descrii>tion 

 has been based is more squat in ap|)earance, with the warts mon^ 

 distinct on the side and back, but with little or iu» granulation on the 

 buttocks. The colors are much the same, except that the lower parts 

 are lighter, the interior faces of the hind legs especially, • hich are 

 yellowish-gray, with the light blotches very obsohite. The light s!»'?ts 

 in the groin are of a pink color, which may be the general hue of the 

 spots. lA'Ugth of body, ^.(JtMnches. 



We have thus«lescribed one extreme of coloration. Tii(> other is quite 

 ditferent. Here the upper parts and sides an* (covered with very dark 

 brown blotches, each with a lighter areola; tiie blotcdies average about 

 two-thirds the size of the tympanum. Some of the blotches on the back 

 are considerably elongated ; those on the sides smaller. The ground- 

 color is of alight olivaceous-brown, with a general and uniform mottling 

 of lighter, as already described. The inferior parts are lighter, with the 

 blotches more obsolete. The fore limbs with several obsolete dark 

 blotches, the hinder with three or four transverse bars on each division; 

 those on the thigh very short. Ilody 2.4i inches long. 



Specimens are found in every stage of c<dorati<)n between these ex- 

 tremes. Sometimes the blotches and bars are barely perceptible when 

 the skin is wet, and again they are more distinct or not at all visible. 

 The smaller specimens are usually the most blotched, the color becom- 

 ing more uniform with increasing size. During life the dorsal spots
