thougli Dot promiuent, but sinootbed over. The buttocks are appar- 

 eutly smoother thau commou, the usual granulation being scarcely 

 discernible. The under parts are entirely smooth. 



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

 denly from the swollen base. The third is longest, the fir.-t and fourth 

 nearly equal, though the latter is rather longer. The fourth toe is long- 

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

 downwards and taper to rather an acute tip; the web is more cnt out 

 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 scarcely 

 beyond the last joint; it is everywhere decidedly 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; sometimes more in irregular spots, sometimes 

 more in vermiculations. Beneath, 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 inferiorly, where they are larger 

 than their interspaces. In the tj^pical 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 appears to be a male. 



A female still larger than the specimen upon which the description 

 has been based is more squat in appearance, with the warts more 

 distinct on the side and back, but with little or no 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, which are 

 yellowish-gray, with the light blotches very obsolete. Tiie light spots 

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

 spots. Length of body, 3.60 inches. 



We have thus described one extreme of coloration. The other is quite 

 different. Here the upper parts and sides are covered with very dark 

 brown blotches, each with a lighter areola; the blotches 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 a light 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. Body 2.44 inches long. 



Specimens are found in every stage of coloration 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 usaally the most blotched, the color becom- 

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