34 MR. EDWAHL) DEGEN ON THE 



are confined principally to the posterior portion of the supraocular 

 region. In the Ruwenzori female they are i-educed to 3 on the left 

 and to 2 on the right side. Di-. Peracca describes these as " very 

 ii'ragular and asynametrical for the two sides, except in a female in 

 which the seiies is a complete one on the left, but totally absent 

 on the right side." Accoixling to Tornier, who in his description 

 omits to quote their number, the supi'aciliary series of granules is 

 incomplete also in Lacerta vauereselli ; but, as he says, confined to 

 the posterior portion, agreeing therefore in this point also with 

 L. jacksoui. 



Galar Scales. — The number of scales between the third chin- 

 plates and the collar-plates varies between 24 and 26 in the Elgon 

 specimens except in one, in which there are 28. This is slightly 

 in excess of the Duke of the Abruzzi's Expedition specimens, in 

 which they are stated to be 22. In the type of the species 

 their number is 25. 



Femoral Pores. — Their number is fairly constant, Avith variations 

 between 16 and 18 in the Elgon series. In one of the two females 

 of the Turin Museum series there is a red uction to 15-14, otherwise 

 17-18 being the normal number. No case of supernumerary pores 

 occurs in any of the British Museum specimens similar to the one 

 female quoted in this respect by Dr. Peracca,, 



Upper Labials {^anterior to the siobocular). — Except for the head 

 of the male, made into a skull, which on its left side showed these 

 to be 5, their normal number throughout the remainder is 4. 

 A male of Dr. Peracca's series shows a similar variation. 



Postocular and Temporal Region. — In one of the specimens the 

 last postocular scute is in contact with the first supra-temporal, 

 similar to what is found in Lacerta inosorensis as figured by 

 Mehely *. In all others it is the upper postocular and the parietal 

 scutes which meet, as in Lacerta horvathi Meh. or~Z. miiralis 

 typica t. 



The 3 to 4 supratemporals are exceedingly small and nari-ow, 

 the first and longest being partially supported proximally by 

 the lateral margin of its underlying postfrontal bone, and 

 therefore visible practically in its greatest extent when the head 

 is viewed from above. 



The number of scutes for the temporal region varies greatly. 

 Those, for instance, forming the second row between the large sub- 

 ocular and the first supratemporal are : 3 for the left, a.nd 5 

 for the right side in the male, the skull of which served for 

 description. 



Similar variation is to be found amongst the scutes in regard 

 to their sculpture, which shows every gradation, from the per- 

 fectly smooth through the granular stage, as pointed out in Mr. 

 Boulenger's description of the typical specimen J, to the faintly 

 keeled or tuberculai' scutes to be met with in some of the Elgon
