Campothera nivosa herberti. 



Dendromus herberti Ai.exander, Bull. B. (3. C, XXI, p. 8q. — 

 Type localitv : Bwanda, Ubanghi River. 



This bird was described by Boyd Alexander in 1908. 



Alexander considered it a species but be compared it with 

 Campothera efuleiieiisis Chubb instead of with Campothera nivosa 

 to which latter form it is much more closely allied. 



The type spécimen from the Ubanghi River as well as a bird 

 collected in Umjoro bv Christy are in beautifui freshlv moulted 

 plumage and in conséquence appear at first sight to be verv 

 distinct. 



Dr. Christy lias now obtained a small séries of 5 birds from 

 Poko on the Uelle River and from Bosabangi (Haut-Ituri). 



This fresh material shows that C. n. herberti rt-aWv verv closelv 

 resembles C. n. nivosa in colouring : the upper parts are however 

 rather brighter and much less olive-green in the Congo birds, 

 moreover the crown of the head is grever in ('. 11. herberti, 

 browner in C. n. nivosa. The best character is however in the 

 length of the bill, the coastal birds (C. n. nivosa) having the bill 

 considerably longer than in C. n. herberti.
