A NEW BATRACHIAN FROM SARAWAK, BORNEO. 

 BY THOMAS BARBOUR. 



Among a small collection of Batrachians taken in Sarawak, Borneo, 

 by Mr. W. T. Hornaday, there are two specimens of an apparently un- 

 described species of toad. This species is nearly related to Nectes subasper 

 Tschndi, from Java. 



Nectes obscurus sp. nov. 



Differing from N. subnsper in the size of the tympanum ; the size of the 

 nostrils; the width of the upper eyelid; and in the distinctness of the 

 metatareal tubercles. 



Head rather small ; snout oblique and obtusely angular; nostrils very 

 small, opening upward and slightly outward ; upper eyelid wide; space 

 between the eyes rather broad ; tympanum distinct but small, less than 

 one-half the diameter of the eye ; fingers slender, the first a very little 

 shorter than the second ; toes long and slender, united by a rather nar 

 row membrane ; subarticular tubercles distinct ; two large metatarsal 

 tubercles. When the hind limb is carried forward along the body, the 

 tarso-metatarsal articulation reaches a considerable distance beyond the 

 tip of the snout. Upper surfaces and sides covered with round and con 

 ical warts of unequal size, the largest evidently porous and arranged in 

 two irregular lines on the dorsal surface. The lower surfaces are cov 

 ered with rather fine granules of unequal size. 



Color (alcoholic specimens), olivaceous above, lighter below; the hind 

 legs banded and mottled with a darker color.
