VARIETIES OF THE WALL-LIZAED.

50 to 60 scales correspond to the length of the head. 



The masseteric disk is always present and usually well developed ; in two specimens 

 the parietal does not touch the upper postocular. Some females closely resemble the 

 striped form of var. quadrilineata, and some males are also very suggestive of the 

 so-called L. genei. The belly is unspotted in all the specimens. 



There are also 9 specimens from a rocky island near the mouth of St. Paul's Bay, 

 presented by Capt. Lynes (PI. XVII. fig. 7), 6 of which are here tabulated : — 



In three specimens the parietal shield does not touch the upper postocular. Two of the 

 males have black spots on the belly, forming two longitudinal bands ; the blue colour 

 occupying the outer ventral shields forms an uninterrupted band from axil to groin. 



Two of the specimens, a male and a female, agree in this anomaly, that the fronto- 

 nasal is divided into two, with an azygous shield between them and the prsefrontals. 



Of the Filfola Eock form, specimens collected by Mr. Despott were received at the 

 Zoological Gardens in 1910, and are still living. The belly is black and blue on the 

 sides, copper-colour, orange, or black in the middle in males, dull yellow or black in 

 females ; dorsal spots of a pale green. 



I append particulars of 15 specimens, in spirit, obtained by the same collector, 

 and preserved in the British Museum. 



In the last specimen the masseteric disk is absent. In 5 specimens the parietal 

 shield does not touch the upper postocular. The frontal shield is usually considerabl}
