Rhacophorus macrotis. 



Vomerine teeth in two oblique groups on a level with the 

 front of the choanse, which are very large. Head nearly as 

 long as broad ; skin adherent to the frontoparietals, which 

 are rugose, studded with granules ; snout triangular, a little 

 longer than the diameter of the orbit ; canthus rostralis 

 angular ; loreal region concave ; nostril near the tip of the 

 snout; interorbital space (in the middle) not wider than the 

 upper eyelid, the frontoparietal bones narrowing posteriorly ; 

 tympanum very distinct, as large as the eye. Fingers long, 

 with a distinct rudiment of web ; toes nearly entirely webbed ; 

 disks of fingers about half the diameter of the eye, of toes 

 smaller ; subarticular tubercles moderate ; a very small inner 

 metatarsal tubercle. Tibio-tarsal articulation reaching the 

 tip of the snout ; tibia half as long as head and body. Skin 

 smooth, granular on the belly and under the thighs. Grey- 

 brown above, with a few small dark brown spots ; loreal 

 region greyish white ; a dark brown band from the end of 

 the snout through the nostril, the eye, and the tympanum to 

 the side of the body ; on the tympanum this band expands 

 into a large temporal blotch ; limbs with ill-defined dark 

 cross bands ; hinder side of thighs brown, dotted with white ; 

 lower parts whitish speckled with brown. 



From snout to vent 78 millim. 



A single female specimen, obtained by Mr. Hose at Baram, 

 Borneo. 



This RhacopJtorus belongs to the group of R. macuJatus, 

 It difiers from all the species of that group in the larger 

 tympanum, from R. maculatus and R. cruciger in the absence 

 of a parieto-squamosal arch and in the larger choanse, from 

 R. leucomystax in the narrower interorbital space and the 

 larger choanas, and from R. Colletti in the shorter hind limbs. 



Bnfo surdus. 



Crown without bony ridges ; snout very short, rounded ; 

 interorbital space a little narrower than the upper eyelid ; no 

 trace of a tympanum ; eustachian tubes extremely minute. 

 First finger considerably longer than second j toes one third
