C. h. intermedia is darker below, and smaller (wings, male, 90-98; 

 female, 82-88 mm) than C, h. heuglini (wings, male, 101-105; female, 

 89-94 mm). 



Grote ®^ recorded birds from Mikindani, extreme southeastern 

 Tanganyika Territory, as C. heuglini^ but I do not know whether 

 these birds are intermedia or euronota. 



The southern race, euronota^ occurs at Lumbo, Mozambique, in 

 Gazaland; and probably northward along the coast to the Rovuma 

 River. This form is small, like intermedia^ but more greenish olive 

 above, having practically no slate-blue on the upper back. 



In Nyasaland and the Katanga, south through Rhodesia to the 

 Transvaal, the race subrufescens occurs. This differs from the 

 others in having the middle pair of rectrices blackish brown instead 

 of olive-brown. 



The adult males have wings measuring 101, 101.5, 101.5, 104.5, and 

 105 mm, respectively ; the females, 89, 91, 93, 94 mm. 



On April 18, at Gato River, Mearns collected a nest and two eggs 

 together with the female parent. The nest is a deep cup of straws 

 and fine twigs, externally surrounded by coarser twigs and thicker 

 herbaceous stems. The eggs are somewhat like those of Cossypha 

 caffra but paler. They are uniform pale wood brown and measure 

 25 by 17 and 24 by 17 mm. 



In Uganda this bird breeds in May, June, and October, according 

 to van Someren.®* 



COSSYPHA SEMIRUFA SATURATIOR Neumann 



Cossypha semirufa saturatior Neumann, Orn. Monatsb., vol. 14, p. 7, 1906: 



Bolagoschana, in Doko, southwestern Ethiopia. 

 Specimens collected: 



1 male, Arussi Plateau, Ethiopia, February 24, 1912. 



1 male, Cofali, Ethiopia, March 3, 1912. 



1 male, Malke, Ethiopia, March 3, 1912. 



1 male, 2 females, Aletta, Ethiopia, March 6-10, 1912. 



Sclater ^^ does not recognize this form, but it appears to be per- 

 fectly valid nonetheless. Inasmuch as his account does not satisfy 

 me, I append a resimie of my findings. The races are as follows : 



1. C s. semirufa: The high plateau country of Bogosland south to 

 the vicinity of Adis Abeba. 



2. C. s. saturatior: The lake region of southern Shoa, and the Omo 

 and Doko areas, southwestern Ethiopia, east to the Arussi Plateau. 

 This and the nominate form are olive-greenish on the upper back and 

 may be told from the next races at a glance by this character. The
