The following notes are based on a collection of 900 lizards and 

 chameleons collected by the writer during the campaign in East 

 Africa. Over a thousand specimens were collected, but one box 

 containing lizards from Kerogwe, Handeni, etc., and handed to 

 the S. & T. for transmission to the base, never reached its des- 

 tination. Another box containing half-a-dozen jars of lizards 

 and chamasleons was lost «?^ route for England. Besides these 

 there are a good many specimens in the Nairobi Museum collected 

 by the writer which were not brought home, and therefore were 

 not available for study for the present paper. 



Representatives of all the families of East African lizards were 

 taken, more than half the genera and about one-third of the 

 recorded species. The numbers are distributed as follows : —

The most representative collection was made in Ex-German East 

 Afiica, where the writer spent two and a half years. Six months 

 were spent in Portuguese East and one and a half years in British 

 East Africa. The field-notes are not so extensive as would have 

 been the case had conditions not been so adverse. For nearly 

 twelve months all specimens had to be carried on the i^addie until 

 camp was made, and an opportunity arose to send tJtem back to 

 the base on the returning supply lorries. 



The principal localities mentioned in the following pao^es 

 are : — 



British East Africa : West Mt. Ivenia, Mt. Siswa, Mt. Margaret, 

 Kedong Valley, Thika, Nairobi, Kabete, Kagiado, Bissel,"^ Yoi, 

 Mbunj'i, Mombasa.
