H5 



Habit stout. Roth dermal ridges behind the level of the 

 tubae. Snout short, obliquely truncate; loreal region oblique, 

 feebly concave; interorbital space twice the width of the upper 

 eyelid; eye small; tympanum distinct, 5 /o * ne width of the 

 eye. Fingers and toes with small, but distinct disks; first and 

 second finger about equal in length. Toes distinctly webbed; 

 the heel reaches the tympanum. 



Skin rough, with several longitudinal rows of large warts; 

 smooth beneath; a fold above the tympanum. 



Back light brown, its posterior part and upper parts of the 

 limbs blackish brown; large, light yellow spots in the lumbar 

 region and on the posterior surface of the thighs and the 

 outer side of the tibiae; faded brown beneath. Length 65 mm. 



For this species the establishment of a new genus should 

 perhaps be justified, the webbed toes distinguishing it from 

 the other species of Hylophorbus. 



Habitat: New Guinea (Sattelberg).

 visible. Fingers and toes free, the tips not dilated. Outer 

 metatarsals united. 



No clavicles; procoracoid replaced by a ligament. Omosternum 

 and sternum absent. Terminal phalanges T-shaped.
