BIKDS OF ETHIOPIA AND KENYA COLONY 175 



"If further investigation shows it to be a good subspecies, it will probably 

 be found to be confined to Fernando Po. * • * 



Dr. Reichenow * * * believes the Enprinodes from Cameroon Mountains 

 to be referable to E. o. sclateri, in which case it will probably be found that 

 E. cinereus and E. c. sclateri are synonymous. 



This race is said to be more creamy yellowish on the throat, breast, 

 and upper abdomen than cinerea or grafiviki. 



The distribution of this species, like that of other mountain birds, 

 offers much food for thought. It is very curious, to say the least, 

 that it should occur without any change on Mount Elgon and Mount 

 Cameroon and not in between, but break up into slightly differen- 

 tiated forms on either side, with no such great geographical gap 

 between their respective ranges. 



There is considerable variation in color in this warbler, regard- 

 less of sex, age, season, or geography. Thus, one of the present two 

 specimens has the top of the head much more brownish, less grayish, 

 than the other. The former has the upper back slightly less bluish 

 slate, more olivaceous slate, than the latter. Sassi has suggested that 

 the degree of white in the outer rectrices may be correlated with age. 

 I have not enough material to investigate this point, but there is 

 considerable variation in the few specimens seen by me. 



In his field notes Mearns recorded seeing about 10 of these birds 

 at Escarpment, September 4—12. They are found only in dense 

 forests. 



APALIS FLAVIDA FLAVOCINCTA (Sharpe) 



Euprinodes flavocinctus Sharpe, Joiun. fiir Orn,, 18S2, p. 346: Adi, i. e., Athi 



River, Kenya Colony. 

 Specimens oollected : 



1 male, Lekiundu River, Kenya Ci-lonj% August 8, 1912. 



1 male, Tharaka district, Kenya Colony, Au^ist 14, 1912. 



4 males, 1 female, Tana River, Kenya Colony, August 14-17, 1912. 



All the present specimens have the basal portion of the mandible 

 yellowish, and all lack any trace of a black pectoral mark. It, there- 

 fore, appears that they are all young birds. On the other hand, a 

 series of unquestionably adult birds from the Athi River, and from 

 Nyeri have black bills and have the black pectoral area well de- 

 veloped. These latter birds are also darker generally than the 

 present series. 



Neumann ®^ and Zedlitz *' have discussed the races of this bush 

 warbler, and van Someren ^* has even separated the present form as a 

 distinct species, chiefly because of its long tail. He has, in a more 

 recent publication,*^ shown that long-tailed and short-tailed birds
