94 EINAR LÖNNBERG, BIRDS. 



Corvultur albicollis (Lath.). 



Rchw. II, p. 640. 



This Räven is not a common bird in the country through whicli I passed. I did not 

 observe it but in three different places viz. near Escarpment station, Kanyakeni (south 

 of Meru borna), and at Meru borna. In all these localities specimens were obtained, al- 

 though this species like other Rävens is rather wary. North of Meru borna I never saw 

 it, and I think this place is at the northern boundary line of its distribution, because at 

 Guaso Nyiri another member of the family takes its place viz. Bhinocorax. Corvultur is 

 usually seen in pairs or family flocks. 



Dicruridae. 



Dicrurus adsimilis divaricatus (Lcht.). 

 (= D. afer Lcht. auct.) 



Rchw. II, p. 646. 



This species was f ound as well on the acacia-steppe around Luazomela and Lekiundu 

 rivers as in the thornbush country at Njoro. One specimen was also shot in thick forest 

 at Meru borna, and another at Punda Melia in a tree at the roadside. Iris in a male red, 

 in a female reddish brown. Length of wing in.four males 114 — 128, in a female 112. 



Dicrurus ludwigi A. Sm. 



Rchw. II, p. 652. 



A male specimen was shot in bushes near the Limuru road, Nairobi, the 30 /i2 1910 

 The whole of its lower surface has a very distinct metallic blue gloss. The inner side of 

 the wing has an olive tint. Length of wing 103 mm. 



The testidés were swelled in this specimen indicating the approaching breeding 

 season. 



This species does not seem to have been found in this part of the country before, 

 but C. von Erlanger discovered it at Lower Juba river. 1 



Oriolidae. 



Oriolus larvatus rolleti (Salvad.). 



Rchw. II, p 650. 

 and 



Oriolus larvatus percivali Grant. 



Rchw. III, p. 836. 

 (Pl. III, figs 3 a— 3 c.) 



An adult male which in every way agreed with the descriptions of O. 1. rolleti was 

 shot 2 /i 1911 at the edge of the forest reserve at the Limuru road not far from Nairobi.
