Although closely allied to the preceding, with which 

 it has long been confounded, this species is easily 

 distinguished by several important characters. 



The general habitus is stouter still. Head con- 

 stantly broader than long ; snout more broadly 

 rounded, as long as or slightly shorter than the 

 diameter of the orbit ; eye rather larger ; nostril 

 equally distant from the end of the snout and the 

 eye, or slightly nearer the latter. In some males the 

 tarso-metatarsal articulation reaches a little beyond 

 the eye. Tibia as long as the femur, and as long as 

 or slightly longer than the foot ; the heels usually 

 meet when the legs are folded against the thighs. 

 The foot is usually rather swollen, the digits shorter, 

 and the web fuller, often with rectilinear border in 

 the males. Warts on the upper surfaces usually more 

 prominent and more crowded, not forming sym- 

 metrical chains ; parotoid gland very rarely distinct.
