82 EINAR LÖNNBERG, BIRDS. 



According to Reichenow this species is distributed from Nandi to Arusha. Its 

 distribution agrees thus nearly with that of Turacus hartlaubi and some others, but as 

 a subspecies counted to the same species is to be found in the countries a round Lake Vic- 

 toria, at Ruwenzori, and Fort Mbeni (A. m. pumilus), and another in Cameroon (A. m. 

 obscurns) the species as a whole must be regarded as belonging to the West African förest- 

 fauna. 



Alseonax pseudogrisola n. 



(Pl. IV.) 



A Flycatcher shot at Njoro in the thornbush-country north of Guaso Nyiri 21 U 1911 

 is of considerable interest as it possibly is a geographic race of Alseonax gambagce Alex., 

 discovered and described by Boyd Alexander from »Gambaga, Goldcoast Hinterland. »* 



The dimensions of the present specimen agree rather tolerably with those recorded 

 by Alexander for his species, viz. 



Length of wing in A. gambagce »3 in» = 77 mm.

The general pattern of the plumage is also similar, the main differences being as 

 follows. Alexander says that A. gambagce »is nearly allied to A. murinus but is larger». 

 The present specimen is very unlike A. murinus. Its general colour above is not »light 

 brown» but brownish grey, in fact it agrees closely with the colour termed »ashy grey» 

 in Dauthenay's »Répertoire de Couleurs». 3 There are darker centres to the feathers of 

 the head so that it looks somewhat streaked above in this specimen, which is not men- 

 tioned for A. gambagce. In Alexander's Flycatcher the under parts are said to be »white, 

 tinted with brown on the lower throat, and sides of chest, where there are a few obscure 

 brown shaft stripes». In the present specimen the sides are suffused with brownish 

 grey, not streaked, lower neck and the whole chest is slightly tinged with brownish grey 

 and plainly streaked with dusky, but not with sharply defined shaft stripes. 



The inner secondaries and greater coverts are rather broadly edged with whitish 

 (not mentioned for A. gambagce). Under wing-coverts not pure white but tinged with 

 greyish isabelline. 



Professor Reichenow, who kindly has favoured me with his opinion about this 

 bird, writes in a letter that it resembles Alseonax aquaticus with regard to the colour of 

 the upper parts more than other species of the genus, but it is larger (the wing of A. aqua- 

 ticus being according to the author quoted 4 67 — 70 mm). The under wing-coverts of 

 A. aquaticus appear to be darker as they are termed »graubraun» (1. c), and that species
