at its base, and the innermost is also the smallest. The tips of the 

 fingers and toes are horny, oftentimes black. Granules or tubercles 

 cover the whole upper surface of the body and limbs, with a double 

 dorsal series of quite large pustules, sometimes not very conspicuous. 



The color, as preserved, is of a uniform reddish-brown above, and 

 reddish-yellow beneath, with small black dots on the chest, margin of 

 jaws, and under surface of the linibs. 



Specimens were collected at Singapore.

Observ. — This genus is allied to Bufo, from which it differs chieflj^ 

 by the want of parotid glands and the absence of web. From all 

 the other genera of the bufonine group it may be distinguished by the 

 visibility of the tympanum. It is allied to Engystoma and Breviccps, 

 in having the toes free, but differs from both of them, besides the 

 visible tympanum just alluded to, by an elongated and conspicuous 

 head, separated from the body by a somewhat contracted neck.
