colour-phase has a dark rusty-brown rump and bright 

 •greenish-yellow or green transverse bands and spots, vvhieh 

 are best developed on neck and anterior baek. This light 

 green reticulation is developed from the marking of tho 

 young animals ; the transverse rows of spots fuse and lorni 

 transverse bars and lines, and their colour changes from pale 

 or yellowish grey to green. 



in connection with this process the ground-colour of the 

 botiy becomes darker and often nearly, or totally, obliterates 

 the light areas. The head, neck, and throat become deep 

 brownish black, chest and belly black, posterior portion of 

 belly strongly clouded with reddish. Cheeks below tympanic 

 lighter or darker bluish grey, this colour only sliglitly ex- 

 tending to throat. The two rows of blue spots, so strongly 

 deve]oj)ed in the female, only extend to chest or loins. Now 

 and then these spots are very large on the shoulders. 



In another colour-jjhase the transverse bands are little or 

 not developed, the ground-colour being very dark, nearly- 

 black, and the two rows of blue spots more or less distinct 

 and often the only marking. This style of marking corre- 

 sponds to that of the local lace of Lacerta simonyi, Steind., 

 inhabiting the lloques of Salmore. 



There are all kinds of intergradations between these two 

 forms, and there are also specimens of a uniform deep brown 

 colour.

This foi-m is smaller than the Tenerife race. The largest 

 males measured were about as large as medium-sized males 

 from Tenerife. The structure of the scales is almost exactly 

 as in Lacerta galloti (jalloti, Dum. et Bibr. ; the colour, how- 

 ever, is constantly ditferent. 



S . The variation is comparatively limited, not by far so 

 enormous as it is in the typical race. Markings of male 

 comparatively simple. Bright green spots and transverse 

 bands, so characteristic of most of the Tenerife specimens, 

 always entirely absent. Ground-colour of upper side more 

 or less dark brown with a yellowish or bluish hue. Head, 

 sides of neck, and anterior jjortion of rump, also underside of
