Birds of Cameroon Mountain. 503 



specimens from east Africa is of the same length as that of 

 birds from the west coast. The four examples obtained on 

 Cameroon Mountain are all in different stages of plumage. 



Specimen No. 1, the youngest bird, has the entire under- 

 parts from the chin to the vent strongly washed with dirty 

 olive-yellow, and the lower mandible whitish horn-colour 

 except at the tip. 



Specimen No. 3 is losing the olive-yellow underparts 

 and beginning to assume the cinereous band across the 

 chest. The lower mandible is becoming darker in colour. 



Specimen No. 4 has entirely lost the yellowish belly 

 and throat of No. 3 and has the underparts washed with 

 cinereous ; the bill is similar to No. 3. 



Specimen No. 2 is fully adult, and has the whitish belly 

 of typical E. cinereus when fully mature, and retains the 

 cinereous chest-band, the throat and belly are whitish, aiul 

 the bill has become entirely black. 



I very much doubt whether E. c. sclateri Alexander 

 described from Fernando Po (Bull. B. O. C. xiii. 1903, 

 p. 36) can stand. If further investigation shows it to be 

 a good subspecies, it will probably be found to be confined 

 to Fernando Po. The specimens of E. cinereus here de- 

 scribed from Cameroon Mountain greatly extend the known 

 range of this species westward. 



Dr. Reichenow (Vogel Afrikas, iii. p. 904) believes the 

 Euprinodes from Cameroon Mountain to be referable to 

 E. c. sclateri, in which case it will probably be found that 

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



The following are the variations in wing-measurements of 

 twenty specimens in the British Museum of E. cinereus and 

 E c. sclateri. 



E. cinereus (typical examples from East Africa) 51-58 mm., 

 (type 56 mm.). 



E. cinereus (Cameroon Mt.) 52-55 mm. 



E. c. sclateri (Fernando Po) 52-56 mm. (type 55 mm.).

 the tall trees. ~B. A.]
