In the two males from the Hadramut, there are three bright 

 orange or reddish-brown bands on the back — the first on the nape 

 of the neck, the second behind the shoulders, and the third on 

 the loins. These bands are interrupted on the mesial line, and 

 the first and last are narrow, but the second expands on the 

 sides. Rusty-coloured bars occur at intervals on the tail. The 

 heads are yellowish, and bluish. 



From the list of Arabian reptiles appended to this paper, it 

 will be seen that the species occnrs at Maskat, Aden, the Hejaz, 

 Akabab, and the Siuaitic Peninsula.

Mr. Blanford, a good many years ago, described an Agamoid 

 lizard from Abyssinia which he designated A. annectens, as he held 

 that it served to connect Agama and Stellio, its tail conforming 

 to that of the latter, whereas in other respects it agreed best 

 with the former. A lizard closely allied to it occurs in the 

 country between Makallah and the Hadramut Valley, but it 

 presents certain characters which at once enable it to be distin- 

 guished from the Abyssinian species. 



Head triangular ; snout rather pointed. A prominent median 

 ridge on the snout before the eyes in the adult male, less de- 

 veloped in young specimens. Head-scales of moderate size, and 

 smooth. Nostril small, slightly below the canthus rostralis, 

 directed outwards and backwards. Ear twice as large as the eye- 

 openiug. A prominent spiny eminence at the front border of 

 the ear, and a few spiny scales above it ; a spiny eminence at 

 the lower border of the ear, and two at some distance behind its 

 posterior border. A spine on the hinder aspect of the angle of 

 the jaw, and a line of spiny scales along its outer surface, con-
