The Spotted Robin-Thrush was met with near Lakes 

 Rudolf and Stefauie, also in Uba and Konso, in July and 

 August. Two younger examples, evidently birds of the year, 

 have the spots on the chest distinctly smaller than in the 

 adult specimens and fringed with creamy white. 



Mr. Bannerman (' Ibis,' 1910, p. 695) has noted the 

 difference in size between the birds found in the coastal 

 districts of East Africa and those found inland, a point which 

 Sharpe had already drawn attention to, when he named the 

 coastal form C. rujj'peirnis [cf. Bull. B. O. C. xii. p. 35 

 (1901)].

The Chestnut-breasted Robin appears to be fairly common 

 throughout southern Abyssinia, and specimens were obtained 

 in most months oC the year. Prof. Neumann has already 

 pointed out that the sexes in this species are quite unlike 

 in plumage, and that the females have generally been 

 regarded as immature birds. In the most adult female 

 examples the pale rust-coloured band down the middle of 

 the throat is absent, but in younger specimens it is more or 

 less well represented. Young birds are easily recognised by
