These specimens do not throw any additional light on the 

 relation between this species and P. carteri (Gray) l . 



[We found these strange little beasts on the very hottest stony 

 deserts near Manif, and again amongst the black volcanic rocks in 

 the Abian couutry : they are extremely quick and are also very 

 fragile, tails breaking off without any provocation. I obtained 

 several with a pistol by shooting at the stone where they sat, the 

 splashes of lead from bullet killing them. When sitting on a stone 

 the tail is usually curled round, something like a chameleon's. 

 They look almost white when alive. As I passed the stone on 

 which they were, they would move round it so that their head was 

 to be seen over the top. — A. B. P.]

These specimens resemble the examples of this species from the 

 Hadramut in their large dorsal scales. They consequently differ 

 from the Sinaitic and Egyptian lizards ; but as this is the only 

 feature by which they can be distinguished, and as they have the 

 third digit the longest, possess an enlarged plate under each claw, 

 aud have brown spines on the transverse plates of the digits, all 

 of which are characteristic of this species, the enlargement of the 

 dorsal scales is only a local variation which begins to show itself 

 to the north at Medina, where the species is traced to the south 

 from the Sinaitic Peninsula.
