what he would have considered specimens from Escarpment. How- 

 ever, the present two birds are larger than one from the Honi River, 

 southwest of Mount Kenya, which locality would seem to come 

 within the range of gra7ivihL They have wings measuring 51 and 



56 mm, respectively, while the Honi River female has a wing length 

 of 50 mm. The figures given by Granvik for cinerea are 53 to 



57 mm; those for minor { = granviki), male 52, female 49 mm. It 

 appears then that if the two forms are distinct, the birds from the 

 Kikuyu Escarpment are nearer to the typical race. Sclater '''' does 

 not recognize granvik?', but as he bases his decision largely on 

 Gyldenstolpe's comments (and Gyldenstolpe allows the eastern race 

 to stand), it seems that, for the present at least, granviki must be 

 given the benefit of the doubt. 



There are no color differences between granviki and cinerea, those 

 given by Granvik being wholly individual in nature. 



The ranges of the races of the brown-headed forest warbler may 

 be summed up as follows: 



1. A. c. dnerea: The highlands of Uganda and extreme south- 

 western Kenya Colony (east to the Kikuyu Escarpment), and reap- 

 pearing again on Mount Cameroon and the highlands of Adamaua, 

 and in the mountain forests west of Lake Tanganyika. 



Reichenow ^® has recorded cinerea from the highland forest west 

 of Lake Tanganyika. Sassi " has listed the same specimens, all col- 

 lected by Grauer. These records appear to have been overlooked by 

 Sclater. 



2. A. c. granviki: The highlands of central Kenya Colony from 

 Mt. Kenia and the Honi River to Nairobi and Kiambu (doubtfully 

 distinct from cinerea). 



Recently, van Someren *° has recorded ^^Euprinodes cinerea d/n- 

 erecC from Marsabit in northern Kenya Coyony. He says nothing 

 about granviki, and it is therefore probable that he considers it iden- 

 tical with cinerea. If granviki be maintained, however, the Marsa- 

 bit birds would probably have to be referred to that race. The 

 locality is a new one for the species and constitutes a very remark- 

 able northeastern extension of range. 



3. A. c. sclateri.' The islands of Fernando Po and Sao Thome in 

 the Gulf of Guinea. I have seen no material of this form, but Ban- 

 nerman ^^ writes that he doubts very much if sclateri can stand.
