E. LÖNNBERG, SOME INTERESTING EAST-AFRICAN BIRDS. 3 



disappear on the outer qiiills. Three or four broad, although 

 badly defined black cross-bands can also be discerned on 

 the central tail-feathers, but they become also more and more 

 obsolete on the outer ones. 



Length of wing 212 mm. but this measurement is probably 

 too small, because the quills are much worn. Culmen from 

 cere 15,3 mm.; tarsus 63 mm.; tail 183 mm. 



This dark Hawk is evidently a bird adapted to the life 

 in dark forests. It is, however, difficult to decide whether 

 it represents a constant local race, or only is a melanistic 

 aberration. Against the latter hypothese speaks the fact 

 that the white markings on the nape and tail-feathers are 

 not obscured. It has therefore appeared convenient to give 

 it a subspecific name. 



Campepliaga martini Jackson. — Two female specimens 

 from Londiani V^ 1914. This Cuckoo-Shrike was only a few 

 years ago described from N'andi, thus the present locality is 

 not very far distant from the type-locality, but appears ne- 

 vertheless worth recording. As Jackson only defines the 

 yellow colour of the under parts with the following words: 

 »Differs from the female of C. quiscalina in having the chest 



and rest of underparts much paler yellow» — — this 



might possibly be misunderstood in such a way that the 

 underparts of C martini were påle yellow. This is, however, 

 not the case. According to the nomenclature in Dauthenay: 

 Rép. de Couleurs, the colour in question may be termed 

 »Buttercup Yellow» (n:o 22, 3). 



One of the specimens which probably is young has the 

 throat washed with isabelline, and crown and nape with an 

 olivegreen tint produced by narrow edges to the feathers. 



Length of wing in both specimens 99 mm. 



Zosterops bayeri n. sp. — The collection contains two 

 typical specimens of Zosterops jacksoni Neum. from Elgon, 

 and a third speeimen, a male, from Londiani which in several 

 respects differs from the first mentioned so that it probably 

 represents a separate form which I venture to name for the 

 collector. 



Upper parts a little more yellowish than Dauthenay's 

 lightest shade of »sap green» (1. c. 280, 1) but more saturated
