Pupil horizontal. Tongue free and deeply notched behind. Vo- 

 merine teeth. Tympanum distinct. Fingers more or less webbed, 

 the two inner opposite to the two outer ; toes webbed ; tips of 

 fingers and toes dilated. Outer metatarsals separated by web. 

 Omosternum and sternum with a bony style. Terminal phalanges 

 obtuse. 



Tropical Africa. 



This genus closely approaches the preceding, from which it differs 

 in the curious dispositioti of the fingers, the two inner being oppos- 

 able to the two outer, resembling to a certain point the grasping 

 hand of Chameleons. This character, however, is much less dev&- 

 loped in 0. rufescens, -which constitutes a link towards Bhaco- 

 phorus.

Vomerine teeth in two oblique groups between the choanse. 

 Head longer than broad; snout rounded, longer than the greatest 

 orbital diameter, with indistinct eanthus rostralis ; loreal region not 

 concave ; nostril much nearer the tip of the snout than the eye ; 

 interorbital space broader than the upper eyelid ; tympanum half 

 the width of the eye. Inner fingers webbed at the base, outer ones 

 nearly to the disks ; toes moderate, entirely webbed ; disks of fingers 

 as large as the tympanum, of toes smaller ; subarticular tubercles 

 small ; a small inner metatarsal tubercle. The hind limb being 

 carried forwards along the body, the tibio-tarsal articulation reaches 

 between the eye and the tip of the snout. Above with a few small 

 tubercles; beneath granular ; a fold above the tympanum. Upper 

 parts brown; a rather indistinct dark cross band between the 

 eyes.
