Var. MAUEITANICUS, Doumergue. 



Distinguished from the var. belli by the dorsal scales, which are flat, 

 rliom))ic, sulnml)ricate, and strongly keeled from the nape or between 

 the shoulders to the base of the tail, the keels sharply defined, exactly 

 as in the var. lineomaculatns, from which it differs in the subocular 

 bordering the mouth, between the fourth and fifth upper labials.* 



Suture between the nasals j to ^ the length of the frontonasalf ; 

 the distance between the second loreal and the anterior supraocular 

 sometimes longer than the latter, rarely a little shorter ; often two 

 series of granules between the supraoculars and the superciliaries, of 

 which there are 5 or 6, rarely 7 ; tympanic shield constantly present. 

 Tail ly to 1|^ times as long as head and body. 



53 to 65 scales across the body. 22 to 26 femoral pores. 20 to 23 

 lamella." under the fourth toe. 



Coloration as in var. belli, but adult often with Jilack spots on the 

 vertebral area. Doumergue mentions a series of yellow s})ots on the 

 sides and a yellow streak just above the ventral region. Tail often 

 pink, bright vermilion in females during the breeding season. 



* Doumergue, who has examined many specimens, has met with but a single 

 exception. 



t Which is longitudinally divided into two iu one speeinicn only (S. fruz).
