2 Mr. C. H. B. Grant on a Collection of 



joined Capt. Cozens at Nairobi on the 17th of the follow- 

 ing month. 



Two separate trips were made during the few months 

 spent in East Africa ; the first from Kijabe Station, south- 

 wards to the Anglo-German Border, and back to Naivasha 

 Station, between Sept. 24 and Dec. 9, 1912 ; and the second 

 trip starting from Nakuro Station, northwards through the 

 always interesting Rift Valley, and across to Nimule and 

 Gondokoro on the AVhite Nile, between Dec. 21, 1912, 

 and March 5, 1913. 



A few birds were also obtained at Kikuyu, on Mr. Judd's 

 farm, on Sept. 21, 22, and 23, before starting for the Anglo- 

 German Boundary, and again on the return at Lake 

 Naivasha on Dec. 12, before leaving for the north. 



The new subspecies described here or in the Bulletin of 

 the B.O.C. are three in number, as follows : — 



Pterocles quadricinctus lowei, Stigmatopelia senegalensis 

 sokotrce, and Scopus umbretta bannermani. 



The classification followed is that of Dr. Sharpe's ' Hand- 

 list of Birds, ^ and in every case I have given reference only 

 to the original description of each species or subspecies ; 

 all these have been personally checked, and where other 

 works have been mentioned, the reference has been included 

 in the matter under discussion. 



I have also followed the modern and useful rule of 

 trinomials wherever necessary, and have endeavoured to 

 keep strictly to priority, as only by this means can all 

 controversy on the question of names be ultimately 

 eliminated. 



I have to thank Mr. Ogilvie-Grant for so kindly allowing 

 me to work out this collection, and for much help and 

 advice, Mr. Tom Iredale for very considerable help on 

 questions of nomenclature, and Mr. W. L. Sclater for 

 valuable assistance. 



I also have to thank Mr. Charles Chubb and Mr. Thomas 

 Wells, of the Bird Room, for much assistance.
