BIRDS OF ETHIOPIA AND KENYA COLONY 71 



kikuyuensis may be told from rolleti on the basis of size, the two 

 former being larger (wings, 132-147 mm), the latter smaller (wings, 

 males, 115-132 mm). Of the larger two, kikuyuensis is darker, 

 deeper greenish, less yellowish above than -permistus, but it is not 

 always easy to identify single specimens. 



The series of rolleti average considerably lighter, more yellowish 

 above, especially on the nape and rump, than permistus. Inasmuch 

 as the two are found so close together in southern Shoa, I append in 

 tabular form the measurements of the present series of both forms 

 (table 9). 



The subadult bird from Malke has ,a black bill but is otherwise 

 similar to fully adult birds, except that there is no black in the tail. 

 The dark areas in the outer rectrices are dark greenish olive becom- 

 ing darker toward the terminal part (the dark areas cover approxi- 

 mately the basal two-thirds of the feathers) . 



One of the Aletta birds is somewhat abraded ; all the other speci- 

 mens of pertnistus collected are in fresh plumage. 



According to Neumann,^" permistvis (,as well as moTmcha) inhabits 

 the highlands at altitudes of from 2,200 to 3,000 meters. 



Besides the specimens collected, Mearns noted permistus as follows : 

 Aletta, March 7-11, 1,000; Loco, March 13-15, 20 birds; Galana 

 Eiver, March 19-20, 6 seen; Black Lake Abaya, M^rch 21^23, 6 

 noted. 



The male and female taken on March 4 were stated by the collector 

 to be a mated pair.

Oriohis rolleti Salvadori, Atti Soc. Ital. Sci. Nat. Milano, vol. 7, Riunione a 



Biella, p. 161, 1864 : White Nile between lat. 4° and 5" N. 

 Specimens collected : 



6 arlult males, 4 adult females, Gato River near Gardula, Ethiopia, March 

 31-May 25, 1912. 



1 immature female, Bodessa, Ethiopia, May 31, 1912. 



1 adult female, Turturo, Ethiopia, June 15, 1912. 



As already mentioned under the preceding form, there is some 

 question as to whether these specimens are to be considered reichenoivi 

 or rolJ-eti^ and my reasons for their present disposition need not be 

 repeated here. 



The immature bird has the forehead and crown black, the feathers 

 margined with yellow, giving these parts a mottled appearance. The 

 chin and throat are yellow, narrowly streaked with black. There is 

 no black, but only grayish greenish olive on the rectrices. The bird 

 is in very fresh plumage.
