BIRDS OF ETHIOPIA AND KENYA COLONY 471 



Shelley ^^ writes that the plumage of the young differs from that 

 of the adult in being more streaked on the breast. This is not all; 

 the breast and upper abdomen are slightly washed with pale yellow 

 in the immature bird, and the margins of the crown feathers are 

 paler, more whitish in young examples. 



The size variations of the adults are as follows : Males — wing, 63-67 

 (average, 65.4) ; tail, 40-44 (42) ; culmen, 7.5-9.5 (8.5) ; tarsus, 12-13.5 

 (13 mm). Females— wing, 63-65 (63.8); tail, 39.5-42 (40.7); cul- 

 men, 8.5-9 (8.6) ; tarsus, 13-13 (13 mm). 



Fringilla angolensis Gmelin^^ is preoccupied by Fringilla ango- 

 lensis Linnaeus ^^ and therefore can not be used for this seed-eater. 

 The next oldest name is Linaria atrogularis A. Smith.-^ The South 

 African and Angolan race therefore becomes PoUospiza atrogularis 

 atrogularis (A. Smith) and the other subspecies remain as before but 

 have the specific name atrogularis. If, as Zedlitz-^ suggests, the 

 Angolan birds be considered distinct, they would need a name. 



Van Someren ^° found this seed-eater to be a partial local migrant 

 in Kenya Colony. He found the birds breeding there from May to 

 June and from December to January. Jackson ^^ found a nest near 

 the Guaso Molo Kiver, Kenya Colony, in September. In tlie Harrar 

 area of Ethiopia, Erlanger ^^ found a nest on May 22.

Sclater ^^ considers affinis Kichmond a synonym of striolata. I 

 have carefully compared Richmond's type and paratypical series 

 with the present birds and find Sclater's conclusion to be justified. 

 Van Someren^* writes that birds from the forests of Nairobi south 

 to Ukambani and Kilimanjaro are separable from Ethiopian ex-
