REPTILIA. 449 



longest hind toe reaching the eye when the hind leg is 

 laid along the side. Fore toe just extending back to 

 the thigh. 



I obtained two specimens of this apparently new 

 Agama near the base of the pass leading from Komayli 

 to the highlands. In one the tail is imperfect. The 

 species forms an unmistakeable link between Agama 

 and Stellio, for although the structure of the taU scales 

 is that of the latter, they being arranged in distinct 

 rings, the animal otherwise agrees best with the former.

This Lizard was common on granite rocks about Eairo 

 near Af Abed, north of the Lebka, at about 3,000 feet 

 above the sea. The head in many specimens was bright 

 blue in colour, chin scarlet. Doubtless these colours are 

 seasonal as in Calotes.
