A new Agamoid Lizard from MasTcat. 



In going over the species of the genus Agama added to the 

 British Museum collection since the appearance of the first 

 volume of Mr. Boulenger's ' Catalogue of Lizards,' I found the 

 following species from Maskat to be one hitherto unrecognized, 

 and I have Mr. Boulenger's permission to describe it. 



Agama jatakaei, n. sp. 



Agama isolepis {not Boulenger), Boulenger, Ann. & Mag. N. H. 

 (5) XX. 1887, p. 407 '- 



Body elongate, not depressed ; head large, more or less tri- 

 angularly cordate ; snout moderately pointed ; canthus rostralis 

 short, not defined anterior to the nasal shield, which is circular 

 with the nostril directed upwards and backwards, and perforated 

 in the hinder part of the shield internal to or on the canthus 

 rostralis ; ear considerably smaller than the eye-opening, with a 

 fringe of pointed scales along its upper border. Upper surface 

 of the head, in adults, with convex scales, especially large along 

 the, mesial line ; scales on the temporal region large, generally 

 well keeled, but sometimes nearly smooth ; scales above, below, 

 and behind the ear and on the occipital region with sharp, 

 prominent, mucronate points. Body covered above with large, 

 equal, strongly keeled, mucronate scales gradually diminishing in 

 size on the sides, where they are about half the size of the dorsal 

 scales and without keels, but furnished with sharp points ; 

 about 90 scales around the middle of the body ; ventrals strongly 

 or moderately keeled. Limbs well-developed, covered with 

 regular, moderately large, strongly keeled, slightly mucronate 

 scales ; the wrist generally reaches the nostril, but occasionally 

 to the snout, and the tip of the fourth toe extends to the ear, or 

 it may full somewhat short of it. Tibia longpr than the skull. 

 Tail considerably longer tlian the body and head, rounded, rather 

 thick at the base, especially in the males, and covered with 

 strongly keeled imbricate scales nearly as large as the dorsal 

 scales. A large gular pouch in both sexes, with the usual gular 

 and short prsehumeral fold. Neither prseanal pores nor callose 

 scales are present. 



General colour of the upper parts olive sufi'used with brownish, 



' When Mr. Boulenger made this identification, he had only one epecimen 

 before him, and that a female.
