to the high and low countries. Only 30 species out of the 1 84 

 secured occurred in both districts, and several of these were 

 birds of prey or Avater-birds, to whom the change in altitude 

 would not be of great account. Doubtless there were others 

 which I did not happen to see in both places, although they 

 occurred there, but they were not noticeable at that time of 

 year. The altitude of the Tsavo River is roughly 1800- 

 2000 ft., that of Thika 5000 ft. The following is a list of 

 the species I saw in both places : — 



Dicrurus adsimilis.

I have to thank the authorities of the Natural History 

 Museum for allowing me to work out the collection there, 

 also Mr. Wells, of the ^5ird-R.oom, for much assistance. 

 Particularly also I am indebted to Mr. W. L. Sclater for 

 very kind assistance and advice.
