Birds from British East Africa and Uganda. 307 



races of this rather uncommon Nightjar appear to be as 

 follows : — 



Caprimulgus trimaculatus trimaculatus. 



Scutornis trimaculatus Swaius. op. cit. 



Range. Senegal^ where doubtless Svvainson's specimen was 

 secured. 



I think it doubtful if tlie Senegal bird is really different 

 from the Gold Coast Colony race, but as Svvainsou gives a 

 wing-measurement of his bird, a male by the description, as 

 8 inches = 203 mm. (which is probably incorrect), and as I 

 have not seen specimens from Senegal^ I am compelled for 

 the present to keep this race separate. 



Caprimulgus trimaculatus tristigma. 



Capr-imulgus tristigma lliipp. op. cit. 



Of tljis, 1 consider that Caprimulgus goslingi Alex. op. cit. 

 must become a synonym. 



Range. Abyssinia, British East Africa, and Gaima Range, 

 headwaters Kibali River, eastern French Congo. 



Wing in males 184-170 mm., females 170 mm. Riippell 

 gives the wing-measurement of his type as 6*9 inches = 

 175 mm., and Alexander gives exactly the same for his type. 



Caprimulgus trimaculatus lentiginosus. 



Caprimulgus lentiginosus Smith, op. cit. 



Range. From Cunene River to Great Namaqualand, 

 Rhodesia, and the Transvaal. 



Wing in males 188-185 mm., females 187-183 mm. One 

 bird from Ru^■tenburg, Transvaal, a male, has the wing no 

 less than 195 mm., but this appears to be abnormal. Smith 

 gives the wing-measurement of his type as 7'Q inches = 

 193 mm., but the specimen which is said to be liis type is 

 now before me and is a female judging by the lack of white 

 on the tail-tips; it has the wing 184 mm. = 7*3 inches. 



Caprimulgus trimaculatus sharpei. 

 Caprimulgus sharpei Alex. op. cit. 

 Range. Gold Coast Colony and Cameroons. 

 Wing in males 176-170 mm.
