former (which, as far as I know, is represented only by the unique 

 type). I have examined the type of heniensis and have compared it 

 with specimens of leueophrys from Escarpment and Ruwenzori and 

 find it to be perfectly distinct. Of course, it must be admitted that 

 I have seen only one Mount Kenya bird {keniensis) , and van 

 Someren -^ has recorded that a bird from the Aberdare Mountains 

 does not differ from topotypical leacophrys from Mount Elgon. It 

 seems, then, that kenieiisis is wholly restricted to Mount Kenya. 

 There are three forms of this crombec, as follows : 



1. S. I. leucophrys: Ruwenzori to Mount Elgon and to the Aber- 

 dares and Escarpment. 



2. S. I. keniensis: Known only from Mount Kenya. This race is 

 somewhat paler above, less brownish, more olivaceous on the back, 

 has the superciliary stripes posteriorly suffused with light brownish, 

 and is generally paler below. 



3. S. I. cKlovonota: The eastern Belgian Congo from the forests 

 west of Lake Tanganyika and the Kivu district to southern Ankole 

 in Uganda. This race has a yellowish-green back. 



The present specimen is in fresh plumage and has the following 

 dimensions: Wing, 54; tail, 23; culmen from base, 10; tarsus, 19.5 

 mm. An unsexed bird from the eastern slopes of the Ruwenzori 

 range is slightly larger: Wing, 58.5; tail, 24.5; culmen, 11; tarsus, 

 21 mm.

Eremomelfi griseoflava Heuglin, Journ. fiir Orn., 1862, p. 40 : Bogosland. 

 Specimens collected: 



1 male, Dire Daoua, Ethiopia, December 9, 1911. 



1 male, 1 female, Sadi Malka, Ethiopia, February 2, 1912. 



1 male, Serre, Ethiopia, February 13, 1912. 



In northeastern Africa no fewer than seven forms of this warbler 

 are known to occur. The material available for study has been in- 

 adequate to attempt a thorough review of these races, but it sup- 

 ports the conclusions arrived at by Sclater.^^ The seven forms are 

 as follows: 



1. E. g. griseoflava: The Red Sea Province of the Sudan, Eritrea, 

 Bogosland, Sennar, south through Ethiopia to northern Shoa and to 

 Gurraland. 



2. E. g. archerl: Northern British Somaliland. 



3. E. g. alexanderi: From the White Nile to Kordofan and Lake 

 Chad.
