canthus rostralis distinct, curved ; loreal region very oblique, 

 concave; nostril nearer the tip of the snout than the orbit; 

 interorbital space as broad as the upper eyelid; eye very 

 large ; tympanum very distinct, half the diameter of the eye, 

 or slightly more; disks of fingers smaller than the tympanum, 

 a little larger than those of toes; first finger shorter than 

 second, which is as long as fourth; no distinct rudiment of 

 pollex; fingers webbed at the base; toes ^/^ webbed; subarti- 

 cular tubercles small; a small, elliptic inner, and a still smaller, 

 sometimes quite indistinct outer metatarsal tubercle; no tarsal 

 fold ; the heel reaches the tip of the snout or nearly so far. 



Skin smooth above, belly and lower surface of thighs granulate. 



Uniform green above, white beneath ; hinder side of thighs 

 brown. From snout to vent 54 mm. 



Male with an internal subgular vocal sac and brown rugo- 

 sities on the inner side of the first finger.

Tongue nicked behind ; vomerine teeth in two small trans- 

 verse groups in the middle between the choanae. Snout rounded, 

 as long as the eye; canthus rostralis rounded; loreal region 

 concave; tympanum half the diameter of the eye. Fingers 

 webbed at the base ; toes more than half webbed. 



Belly and lower surface of thighs granulate. 



Blackish brown above, with white (in life yellow?) streaks, 

 viz. three longitudinal streaks along the back, the median one 

 from the tip of the snout to the vent, the lateral ones be- 

 ginning from the upper eyelids; a cross-bar between the eyes 

 and a streak from the loreal region to the angle of the mouth 

 or to below the tympanum ; lower surfaces white. From snout 

 to vent 31 mm. 



H. thesaurensis is strongly resembling H. macgregori, with 

 which it has been confounded, and which it seems to represent 

 on the Solomon islands. Boulenger supposes, that it is a 

 Indo-australian amphibia. 4
