76 EINAR LÖNNBERG, BIRDS. 



Some specimens have the secondaries över more than the basal half white and then 

 only one white bar across the black of the outer part of the feather, some others have 

 these quills black with three white bars, the two basal of which are very broad. The 

 latter is the case with the Embu specimen, but I do not think this to be of importance. 1 



I saw Hopoes in the thornbush north of Guaso Nyiri as well but unfortunately did 

 not shoot any so that I cannot state if those belonged to this species or to U. somaliensis, 

 although the latter appears most probable, to judge from other facts. It appears that 

 Lekiundu may be the northeasternmost locality for U. africana.

Along Guaso Nyiri below Chanler Falls small family flocks of this bird were often 

 seen and heard when they climbed in the doum-palms along the riverside. 



Length of wing 135 — 149 mm. One of the males, although otherwise in full plumage, 

 has the throat light brown, like a young male with the bill still rather short and black.

A male specimen of Irrisor shot in tlie thornbush at Njoro ' 2b lt 1911 has no brownish 

 feathers on the throat or elsewhere. It is not particularly young but the bill is wholly 

 black and short: culmen 31 mm, length of wing 130 mm, length of tail 186 mm. The 

 wings are glossy steelgreen or steelblue in different shades of light, the tail glossy blue 

 with some slight shading into violet. The plumage otherwise only with slight bluish or 

 violet gloss. Top of head more bluish green in spöts. White markings as in Irrisor sene- 

 galensis somaliensis, of which it may only be an individual aberration or a dwarf.

Two female specimens shot in the forest near Meru borna 3J /i 1911 have very little 

 white on the head. In one of them the forehead and throat are white but nothing more: 

 in the other there are only a few white feathers in the angle of the lower mandible. A 

 third specimen, a male shot on the north eastern side of Kenia at an altitude of 2700 metres 

 ( 27 /3 1911) has a few white feathers on forehead and throat. Otherwise all these speci- 

 mens are in splendid glossy, plumage and certainly not young. 



The dimension are as follows:

1 There is of course no white band across t ho primaries, and it is thus not the question ahout any l . 

 somaliensis» but the variable extension of the white proves the slight foundation of U. somaliensis.
