Genus LACERTA Linnaeus 



LACERTA JACKSONI Boulenger 



Lacerta jacksoni Boulenger, 1899, Proc. Zool. Soc. London, p. 96, pi. 10. (Mau

1 (U.S.N.M. 49098) Lukosa River, K. C. (Sm. Afr. Exped.) 1909. 



1 (U.S.N.M. 49288) Mt. Gargues, K. C. (Heller) 1911. 



3 (U.S.N.M. 49377, 49454-5) Kenya Colony. (Heller) 1911. 



The largest specimen (49454) measures 187 (73 + 1 14) mm. Angel ^^ 

 has shown that Lonnberg's race Icihonotensis from Kilimanjaro can 

 not be maintained. Mount Gargues is a new record for its distribu- 

 tion, and Heller's label states that it was obtained at the summit at 

 7,100 feet on August 27. Besides its occurrence on the Lukosa River 

 (also called the Yala River), which is in the Kegamaia country at the 

 foot of Mount Elgon, the species has been recorded froni the Mount 

 Ruwenzori, the Kivu Mountains, the Usambara Range, and in the 

 remnants of rain forest on the outskirts of Nairobi.

3 (U.S.N.M. 49410-2) Summit Aberdare Range, K. C. (Heller) 1911. 



Angel has already recorded three of these lizards from Mount
