202 MR. G. A. BOULENGER ON LACERTA. SIMONYI. [Mar. 17, 



Femoral pores 31 — 31. Tail nearly once and a half as long as head 

 and body (reproduced) ; caudal scales strongly keeled, with truncate 

 posterior border. Blackish brown above ; a lateral series of six or 

 seven roundish pale yellow spots, gradually decreasing in size from 

 front to back, the first above the shoulder ; three other large 

 yellowish spots lower down on each side, extending on to the outer 

 ventrals ; lower parts brown, yellowish in the middle of the belly ; 

 some of the ventrals tinged with red.

The teeth have tricuspid crowns, the lateral cusps being stronger 

 and more regular than in any of the adult Lacerta which I have 

 examined. They differ much from those o{ a Lacerta ocellata of 

 similar size in not being worn down, as may be seen from the figures 

 (Plate XIX. figs, d, e) appended to this paper, which represent the 

 lateral teeth in the two Lizards. 



Lacerta simonyi has been correctly compared by Steindachner with 

 L. galloti from the Canary Islands, which must be regarded as its 

 nearest ally. Its affinities to L. ocellata are, however, equally 

 striking, for though it agrees with the former in its single postnasal, 

 its five anterior labials, and the number of femoral pores, it differs 

 from it and agrees with the latter in its temporal scutellation and its 

 denticulate collar. It appears to me, therefore, that L. ocellata and 

 L. galloti are more intimately connected than has been hitherto 

 believed.
