former was with us throughout our entire trip, the latter until we left East Africa, and 

 both worked as zealously and efficiently for the success of the expedition as any other 

 member thereof. 



We spent eight months in British East Africa. We collected carefully in the various 

 portions of the Athi and Kapiti plains, in the Sotik and around Lake Naivasha. Messrs. 

 Mearns and Loring made a thorough biological survey of Mount Kenia, while the rest 

 of the party skirted its western base, went to and up the Guaso Nyero and later visited 

 the Uasin Gishu region and both sides of the Rift Valley. Messrs Kermit Roosevelt 

 and Tarlton went to the Leikipia Plateau and Lake Hannington, and Dr. Mearns 

 and Kermit Roosevelt made separate trips to the coast region near Mombasa. On 

 December 19 the expedition left East Africa, crossed Uganda and went down the 

 White Nile. 



North of Wadelai we stopped and spent over three v.eeks in the Lado, and from 

 Gondokoro Kermit Roosevelt and I again crossed in to the Lado, spending eight or ten 

 days in the neighborhood of Rejaf . In Gondokoro we were met by the steamer which 

 the Sirdar, with great courtesy, had put at out disposal. On the way to Khartoum 

 we made collections in Lake No, and on the Bahr-el-Ghazal and Bahr-el-Zeraf . We owe 

 our warmest thanks for the generous courtesy shown us and the aid freely given us, not 

 only by the Sirdar, but by all the British officials in East Africa, Uganda, and the 

 Sudan, and by the Belgian officials in the Lado; and this, of course, means that we are 

 also indebted to the home governments of Egypt and Belgium. 



On the trip Mr. Heller has prepared 1,020 specimens of mammals, the majority of 

 large sizes; Mr. Loring has prepared 3,163, and Doctor Mearns, 714, a total of 4,897 

 mammals. Of birds. Doctor Mearns has prepared nearly 3,100; Mr. Loring, 899; and 

 Mr. Heller about 50, a total of about 4,000 birds. 



Of reptiles and batrachians, Messrs. Mearns. Loring, and Heller collected about 

 2,000. 



Of fishep, about 500 were collected. Doctor Mearns collected marine fishes near 

 Mombasa and fresh-water fishes elsewhere in British East Africa, and he and Cuning- 

 hame collected fishes in the ^Vhite Nile. This makes in all of vertebrates: Mammals, 

 4,897; birds, about 4,000; reptiles and batrachians, about 2,000; fishes, about 500; 

 total 11,397. 



The invertebrates were collected carefully by Doctor Mearns, with some assistance 

 from Messrs. Cuninghame and Kermit Roosevelt. A few marine shells were collected 

 near Mombasa, and land and fresh-water shells throughout the regions visited, as well 

 as crabs, beetles, milUpeda, and other invertebrates. 



Several thousand plants were collected throughout the regions visited by Doctor 

 Mearns, who employed and trained for the work a Wunyamvezi named Makangarri, 

 who soon learned how to make very good specimens and turned out an excellent man 

 in every way. 



Anthropological materials were gathered by Doctor Mearns, with some assistance 

 from others. A collection was contributed by Major Ross, an American in the govern- 

 ment service at Nairobi. 



A complete account of the essential features of the expedition has 

 been given by Colonel Roosevelt in his "African Game Trails."* Ac- 

 counts of the larger mammals are given in manual form in Roosevelt 

 and Heller's ''Life-Histories of African Game Animals. "^ Numerous 

 new species and subspecies of mammals collected on this expedition
