without tooth-like processes. Head very large, much broader 

 than long; snout rounded, slightly projecting, as long as or 

 slightly longer than the eye ; canthus rostralis distinct, obtuse^ 

 straight; loreal region very oblique, concave; nostril nearer to 

 end of snout than to eye; interorbital space flat, as broad as 

 the upper eyelid ; tympanum distinct, about 73 the diameter 

 of the eye. Fingers with slightly swollen tips, toes with small 

 disks; first finger extending beyond second, nearly as long 

 as third ; second one a little shorter than fourth ; toes 2 / 3 webbed, 

 the web reaches the disks, except that of fourth toe, two 

 phalanges of which are free ; the web penetrating between 

 the outer metatarsals; subarticular tubercles large; an oval, 

 flattened inner, and a rather indistinct, roundish outer meta- 

 tarsal tubercle ; no tarsal fold ; the heel reaches the temple ; 

 tibia about 2 1 / 3 times in the distance from snout to vent; 

 when the hind limbs are folded at right angles to the body, 

 the heels do not overlap. 



Upper surfaces covered with prominent porous warts of 

 different size ; on each side of the back they are more elongate 

 and confluent, so as to form an interrupted dorsolateral fold, 

 which, however, does not extend beyond the sacrum; a strong 

 fold above the tympanum ; belly and lower surface of thighs 

 feebly granulate, otherwise smooth below. From snout to 

 vent 150 mm. 



Uniform brown above, yellowish beneath. 



Terminal phalanges with a feeble transverse expansion at 

 the tip. 



Habitat: Solomon islands.

Vomerine teeth in two short oblique series behind the level 

 of the choanae and not extending outwards beyond the vertical 

 of their inner edges; the space between the two series equal 

 to or less than the length of one of them ; lower jaw without 

 tooth-like processes. Head large, a little broader than long; 

 snout rounded, hardly projecting, as long as or slightly longer 

 than the eye; canthus rostralis obtuse, slightly curved; loreal
