Ayres). Total length 5 inches, cnlmen 0*4, wing 5-05, tail 2-1, 

 tarsus 0'45. {Mus. G. E. Shelley.) 



Adult female. Similar to the male in colour. Total length S-4 inches, 

 culmen "0-4, wing 5, tail 2-15, tarsus 0-45. {Mus. G. E. Shelley.) 



Young. Onlj' differs from the adult in having rufous edgings to the 

 feathers of the upper parts, lower abdomen, and under tail-coverts. 



Ohs. As with C. paludicola., G. minor, and C. sinensis, there seem 

 to he three races of sootj^-hrown Crag-Martins with rufous throats, 

 represented by forms occupying nearly the same areas of distribu- 

 tion as the three bii'ds above alluded to. Writing in 1S70, 1 ventured 

 to differ from Dr. Finsch's determination of Mr. Jesse's Abyssinian 

 specimens as C. fidigula, and believed that they belonged to a small 

 race of C. rupestris. A larger experience of this group of Crag- 

 Martins has induced me to modify this opinion, and I consider now 

 that Dr. Finsch was more in the right than I was. The Abyssinian 

 specimens certainly belong to C rujiyula, a Martin of the C.-fuligida 

 group, but smaller in size, deeper sooty brown in colour, and with 

 much less extent of rufous underneath. The spotting on the throat 

 ■ in one of the Abyssinian specimens mentioned by me in 1870 is, I 

 find on reexamination of the individual bird, due to abrasion of the 

 plumage, and is too faintly pronounced to be compared with the 

 distinct spotting on the chin seen in every specimen of true G. ru- 

 pestris. The spots are scarcely visible in the examples collected by 

 Harris in Shoa.
