Adult male and female. Iris dark brown ; bill and feet black. 



The specimens killed in August are in very worn plumage and in full moult, the old 

 feathers of the back being much browner than the new ones. The collection also 

 contains specimens in partial moult (chiefly the tail-feathers) procured in January, 

 February, and March. A female killed in December [No. 48] is marked " breeding." 



[A few examples of Mackinnon's Shrike were met with on Ruwenzori up to the 

 forest-line at an elevation of 6500 ft., but they -were not numerous. They were also 

 seen in some of the clearings in the Eturi Forest between Fort Beni and Irumu. —

Dr. Reichenow considers that the representatives of this species, ranging from 

 Angola to the Lake District, should be separated under the name of L. h. congicus, on 

 account of the markings of their outer tail-feathers, which are said to be black with 

 only the tip and outer web white. In this respect the specimen (No. 272) from S.E. 

 Ruwenzori agrees with the description oiL. congicus and differs from most East African 

 specimens of L. humeralis in the British Museum, which have the greater part of the 

 outer tail-feathers white. These range from North Abyssinia southwards to Natal and 

 westwards to Victoria Nyanza. There is a large series of this species in the Jackson 

 Collection from Kikuyu, Eldoma Ravine, Nandi, Elgeyu, Mt. Elgon, Entebbe, and 

 Toro, and, among these, specimens are to be found from several localities with the
