their spotted plumage^ the feathers of both the upper- and 

 underside being spangled with pale fulvous at the tips. 

 Birds in first plumage were procured in May and September, 

 but in the latter month much of the adult plumage had made 

 its appearance on the underparts. 



An immature male, killed in October, has neai'ly assumed 

 the fully-adult plumage, but the crown, back, throat, etc., 

 are still more or less spotted with buff. 



181. Thamnol.ea albiscapulata. 



ThamnoIxBa albiscapulata (Riipp.) ; Reich, iii. p. 703 

 (1905) ; Neumann, J. f. O. 1906, p. 288. 



A few specimens of the Abyssinian White-shouldered 

 Robin were met with, a male in Arussi, east of Lake Zwai, 

 in January ; a pair on the Gudr River in April ; and two 

 males at Sadeteka, in Gomma, in May. It is evidently a 

 much rarer species than the last-named. The female is like 

 the male, but lacks the white shoulder-patch. 



182. Thamnol.ea subrufipennis. 



Thamnohea subrufipennis Reich. ; Reich, iii. p. 702 

 (1905). 



An adult male of the Chestnut-vented Robin, obtained at 

 Kullo on the 26th of May, is the only representative of tliis 

 species in the present collection. It is, however, of especial 

 interest, as the species has not previously been met with in 

 Abyssinia. It was known to range from the vicinity of 

 Lake Victoria to Nyasalaud, and its occurrence at Kullo 

 therefore extends its habitat a long way further north. 

 Both in this species and in the allied T. cinnamomeiventr'is 

 (Lafres.), in which the under tail-coverts are chestnut, the 

 females are quite different in plumage from the males. 

 The head, neck, chest and mantle, as well as the lesser and 

 median wing-coverts, are dark slate-grey instead of black, 

 and the white shoulder-patch is absent.
