EREMIAS SPEKn SPEKU Gunlher 



Eremias spekii Gunthbr, 1872, Ann. Mag. Nat. Hist., ser. 4, vol. 9, p. 381 

 (Unyamwezi, T. T.). — Boulenger, 1887, Cat. Lizards Brit. Mus., vol. 3, 

 p. 84, pi. 4, fig. 2; 1921, Monogr. Lacert., vol. 2, p. 235. — Loveridge, Proc.

7 (U.S.N.M. 49163-7) 49297-8) ? Mt. Sagalla, K. C. (Heller) 1911. 



In referring these lizards to the typical form I mean that they have 

 the subocular bordering the lip, and five dorsal lines of which the 

 median bifurcates upon the neck as described in the Proceedings of the 

 Zoological Society London, 1920 (p. 148). The Ulukenya lizard has 

 these lines so faintly marked and the black markings so accentuated 

 that superficially it presents a rather distinct appearance; it is, how- 

 ever, closely m.atched in these respects by a specimen of Eremias 

 spekii sextaeniata (M. C. Z. 8175) from the Guaso Nyiro district of 

 Kenya Colony which is part of a series of typically striped sextaeniata. 



As far as I can judge, Boulenger is incorrect in saying that the 

 typical form occurs in Uganda. I know of no records other than his 

 "Ndi, Uganda," this should almost certainl}^ be Ndi Station on the 

 Uganda Railway, the station being close to Ndi in the Taita Hills 

 and not far from Mount Sagalla. Much confusion has resulted from 

 the calling of the railway which traverses Kenya Colony the "Ug- 

 anda Railway;" no part of it entered Uganda until quite recently a 

 branch hne has been laid around the northern end of Lake Victoria.

Boulenger, in his monographic revision of the Lacertidae in 1921, 

 did not, though apparently with some hesitation, recognize sex- 

 taeniata as a race. It appears to me, however, from the table of 

 records which he presents on page 239 of the second volume of the 

 Monograph, as well as from Lonnberg's remarks in the reference 

 cited above, which curiously enough escaped tabulation in the Mono- 

 graph, that we are justified in recognizing sextaeniata as a northern 

 race which meets with the "parent" form on, or about, a line corres- 

 ponding approximately to the Uganda Railway in Kenya Colony. 

 The two forms meet at Mtoto Andei (a station on the railway) for
