HIRUNDO SEMIRUFA [antea, p. 395]. 

 Add:— 



Hirundo semirufa, Sliarpe & Wyatt, Monogr. Hirund. pt. i. (1885) ; Beichen. J. f. O. 

 1887, pp. 308, 309 ; Shelley, P. Z. S. 1888, p. 40. 



The differences between H. semirufa and H. gordoni are so slight that it will probably 

 be found that the two forms intergrade, and will have to be treated as one species, of 

 which H semirufa is the larger southern form. The specimens procured by Emin Pasha 

 at Wadelai on the 12th of October have been referred to the latter by Captain Shelley. 



Mr. Bohndorff procured this race at Kassongo, on the Upper Congo, about 4° 30' S. 

 lat., and at Kibongo, between Kassongo and Lake Tanganyika. 



For the geographical distribution of this species, vide infra, Plate 84 [Map]. 



HIRUNDO GORDONI [antea, p. 397]. 

 Add:— 

 Hirundo gordoni, Sharpe & Wyatt, Monogr. Hirund. pt. ii. (1885); Hartert, J. f. O. 

 1886, p. 590; Shelley, Ibis, 1890, p. 163; Beichen. J. f. O. 1891, p. 382; 

 Bocage, Jorn. Sc. Lisb. (2) viii. p. 258 (1892). 

 Hirundo semirufa, Beichen. J. f. O. 1887, pp. 308, 309. 



Dr. Beichenow records the present species from Togo Land. Mr. Hartert observed 

 it at Loko, on the Benue. It was not seen in the villages but on the edges of the 

 forests, and was not very common. The late Mr. Jameson procured it at Tambuya, 

 on the Aruwbimi Piver. 



A mistake has occurred in our account of the present species, where it appears 

 that Mr. Biittikofer had found this Swallow on the Gold Coast, which he has never 

 visited. The sentence (line 26) should read as follows : — " On the Gold Coast it was 

 originally obtained by Dr. Gordon, &c, &c."
