or witli bluish green, and more or less spotted witli yellowish, 

 and the limbs and tail with brownish. The head generally bluish 

 green and yellow; on the back of the neck there are usually 

 indications of two short lonijitudinal brownish bunds. 



This species is closely allied to A. Jlavimaculata, Kiippell, from 

 Jiddah, but is distinguished from it by its large, regular, strongly 

 keeled and mucronate scales, by its less cordate head, which is 

 shorter than the tibia, and by the more strongly keeled character 

 of its caudal scales. It also attains to a greater size, and the 

 scales on the back of the head are somewhat more spinose than 

 in A. flavimaculata, Eiippell. The entire absence of prseanal 

 pores and callose scales in these two species necessitates an 

 alteration in the hitherto accepted definition of the genus Agama. 



A. isolepis, Blgr., which has prseanal ]_)ores, is more allied to 

 A. agilis, Oliv,, than to this species. 



J udging from the number of specimens sent to the British 

 Museum by Dr. Jayakar, it would appear to be well represented 

 at Maskat, It attains to a greater size than A. sanguinolenta, 

 Pallus.
