has fairly light brownish upperparts, with no olive-green tinge; 

 middle of throat brownish, 



2. S. u. erythreae (Salvadori) : Bogosland, Eritrea, the drainage 

 basin of the Barco River, the coastal plain of the Danakil area. 

 This form, which I have not seen, is said to be even paler and purer 

 brown above; middle of throat white. 



3. S. u. omoensis (Neumann) : Southern Ethiopia from Harrar and 

 the Arussi-Galla countries to Djamdjam, eastern and southern Shoa, 

 and the Omo region. This race has the upperparts distinctly washed 

 with olive-green and has the whole throat tawny grayish brown. 



4. S. u. mackenziana (Sharpe) : The highlands of the interior of 

 Kenya Colony from Kikuyu, Mount Kenya, Mount Uraguess, Mau, 

 Escarpment, Burnt Forest, Londiani, Aberdare, and Elgeyu to 

 Mount Elgon. This race is light below, i. e., middle of throat and 

 most of abdomen white; the upperparts brown, washed with olive- 

 green on wings, tail, and upper tail coverts. 



5. S. u. dorcadichroa (Reichenow) : Mount Kilimanjaro. Most 

 similar to omoensis^ but without the olive-green wash on the dorsum ; 

 throat tawny grayish brown. 



In addition to these five, there is a very pale form with white lores 

 in southwestern Arabia. This is the race named yemensis by 

 Ogilvie-Grant *^ from the high mountains of the Yemen provinces. 

 I have seen no material of this race. 



Seicercus alpina appears to be merely an extremely dark version 

 of dorcadichroa, and might well be considered a seventh race. 



S. hudongoensis and S. laeta may represent another specific group, 

 rather than two such aggregates. I have seen no specimens of the 

 former and have merely compared Seth-Smith's description *^ with a 

 single example of the latter. Neither has anything to do with the 

 wnbrovirens group. 



One of the two females is darker, more brownish, less olivaceous 

 above than the other. In size they agree, both having wings 55 mm 

 long; tails, 41-42; culmen, 10; tarsus, 19-19.5 mm. The male has 

 the following dimensions: Wing, 61; tail, 48; culmen, 11; tarsus, 

 21 mm. The dark female resembles the birds from Sciotalit and 

 Antotto discussed by Neumann^" and seems to be an intermediate 

 between omoensis and urnbrovirens. 



The three specimens are in fairly fresh plumage, a fact that, 

 together with Erlanger's observations^^ indicates that the species
