41. A List oi" tlio Jjizjinls of British Tcnilorics in Kast 

 ACi-ica (Ugandu, Kenya Colony, Tanganyika Territoiy, 

 and Zanzibar), with Keys for the diagnosis o£ the 

 Species. By AuTiiuu Loveridge, F.!E.S., C.M.Z.S.

As no work on the Liznvds of the British territories in Enst 

 Africa, as a whole or in part, has ever appeared in tlie English 

 language, the writer hopes that the accompanying keys an<l check- 

 list may prove of nse to liis fellow herpetologists and perhaps 

 help to stimulate an interest in the Lizards of this region. 



l?oth Tornier* and Nieden t have publisheil works dealing 

 with the reptile fauna of German East Africa (now Tanganyika 

 Tei-ritory) and liave included in these many species from British 

 East Africa (now Kenya Colony) and Uganda likely to be fomid 

 in CL E. A. Owing to the many species described by Boulenger, 

 Sternfeld and others, however, both these works may be con- 

 sidered out of date. 



Jjike all herpetologists, I must confess my indebtedness to the 

 writings of Mr. G. A. Boulenger. In the case of the Lizards 

 proper (LacertidiTe) I have adopted, or extracted, from his keyst 

 to suit my purpose. 



Out of the 1 12 species a.nd races considered valid in this jtaper, 

 no fewer than 64 have been de.scribed since the publication of his 

 'Catalogue of Lizards '§. A still more significant fact as to the 

 amount of work done in recent years is that, of the 48 species which 

 appear in the Catalogue, only 15 are recorded from, or credited to, 

 the n.reii dealt with in the following pages, which have perforce been 

 compiled from a mass of papers that have appeared since 1887.
