Sepsina frontoparietalis. 



Snout obtuse, scarcely projecting beyond tlie labial margin; 

 eye moderate ; lower eyelid scaly; ear-opening smaller than the 

 eye-opening. Frontal divided into an anterior (frontal) and 

 a posterior (frontoparietal) shield of equal length ; the frontal 

 proper in contact with the first and second supraoculars, the 

 frontoparietal with the second, third, and fourth ; frontal 

 angularly emarginate on each side by the first supraocular; 

 five supraoculars ; nine supraciliaries ; interparietal longer 

 than broad, shorter than tlie frontoparietal ; fourth upper 

 labial entering the orbit. Twenty-eight scales round ihe 

 middle of the body, equal. Limbs rather elongate, over- 

 lapping when adpressed. The fore limb, stretched forwards, 

 reaches the anterior corner of the eye ; hind limb rather more 

 than half the length of the body. Tail twice as long as head 

 and body. Brown above, each scale with the edges darker ; 

 nape and anterior part of back with interrupted dark brown 

 cross bands ; lower parts whitish.

^A single specimen. 



The division of the frontal shield, whether or not an indi- 

 vidual character, is particularly interesting as showing that 

 the large frontal of Sejjsina and allied genera originated 

 through fusion with the frontoparietal. 



Chamceleon cucuIlatuSj Gray. 



This species has been known for nearly sixty years from a 

 single female specimen. The collection which yielded the 

 novelties described in this paper contained several specimens 

 of both sexes, the females agreeing perfectly with the type 

 preserved in the British Museum.
