The largest specimen I have met with, measured three in- 

 ches in length; and the posterior extremities were four inches 

 and a half long. Color above, cinereous ; abdomen white ; in- 

 terior of the limbs and lower part of the flanks, yellow. Upon 

 the back, two longitudinal rows of dark brown spots, which 

 are generally square, sometimes nearly circular ; in some spe- 

 cimens, these become confluent and produce an elongated 

 band ; in the same specimens, both square and circular spots 

 may occasionally be observed. Between the back and sides, 

 a broad yellowish brown band is seen, commencing at the 

 eyes, and extending the length of the body. Two rows of 

 smaller spots of a similar appearance with those on the back 

 and sides. Snout, pointed. Eyes rather prominent ; pupils, 

 black ,- irides, golden. Tympanum, small, color of the back ; 

 a dark colored line extends from the snout to the eyes, a round- 

 ish spot on the upper and inner side of each orbit, one on the 

 top of the head, and a smaller one below each nostril. Thighs, 

 legs, and tarsus, striped transversely with broad dark bands or 

 oblong spots ; arms irregularly spotted. Back, smooth ; flanks 

 slightly tuberculated ; buttocks, granulated ; fleshy tubercles 

 on the lower surface of the toes at the joints.

This beautiful species is not often met with, inhabiting as it 

 does damp and thick woods ; occasionally it is seen at a great 

 distance from any water, and is very difiicult to be taken on 

 account of its agility in leaping. It is rather smaller than the 

 ^^ palustris,''^ and presents the following characters : above, of a 

 reddish brown color, resembling a dried dead leaf ; sides, varie- 

 gated with green and yellow ; abdomen, white ; under part of 

 the arms and posterior extremities, lighter colored than the back. 

 Snout, blunted. Eyes, prominent ; pupils, black ] irides, gol- 

 den. A broad black band, narrow at its origin, wider at its
