species. It lias been recorded in German East Africa from 

 the Avusha country, and ranges through West Africa from 

 the Congo to Senegambia. 



On placing this skin between the series of C. cinerascens 

 and C. erythrops in the British Museum I observed that it 

 formed a good connecting link. 



66. PsALIDOPROCNE ORIENTALIS. 



Psalidoprocne petiti orientalis Reichen. J. f. O. 1889, 

 p. 277, Usambara. 



Psalidoprocne percivali Grant, B. 0. C. viii. p. Iv. (1899), 

 Buo B. 



I enter this species in the present list because there is a 

 specimen in the British Museum procured by Mr. Alexander 

 Whyte at Zomba in January 1893. 1 did not record it at 

 the time, as I hoped to see more specimens from Nyasaland. 

 P. antinorii from North-east Africa was the nearest ally 

 known to me, for I was unable to recognise it as P. petiti 

 orientalis Reichen. from the original description, and I 

 forgot all about it until Mr. Ogilvie Grant described the 

 species, from a brighter specimen, as P. percivali. On 

 referring to the key to the Swallows given by Dr. Beichenow, 

 Vog. O.-Afr. p. 144, there can be no doubt that the oldest 

 name for the species is P. orientalis. 



Besides the two specimens above mentioned there is 

 another in the British Museum labelled " ^ , 20.9.98 Cherin- 

 gana district, Mosambique (H. S. H. Cavendish)," so that 

 the species ranges from 5° to 20° S. lat. To the north, in 

 British East Africa, there is found P. orientalis (nee Reichen.), 

 Sharpe, Ibis, 1892, p. 306, readily distinguished from the 

 true P. orientalis by having the axillaries and under wing- 

 coverts pale brown, and 1 imagined that this would prove to 

 be a new species with little gloss on the plumage like the 

 young bird from Taveta — P. petiti (nee Sharpe & Bouvier), 

 Shelley, P. Z. S. 1889, p. 359; but I find Mr. Jackson's 

 birds, nine in number, from Mount Elgon, the Ravine, Nandi, 

 and Mau to be identical with examjiles of the species from 

 the Knysua and Natal, which is also represented in the British
