Some uncertainty still exists with regard to JE. cinereicollis, 

 Heuglin. He himself, in 1H7 3, referred it to tricollaris (Orn. 

 Nordost. Afr. ii. p. 1027), but in ' The Ibis' for 1860 (p. 430) he 

 wrote : — " This species is very closely allied to JE. tricollaris, but 

 smaller and different, especially in the tail-markings." This seems 

 to indicate that he had the two species before him from North- 

 East Africa, of which the smaller cinereicollis, " found singly at 

 mountain pools and streams in Abyssinia," would be tricollaris, 

 Vieillot, as were all the specimens brought home from Abyssinia 

 by Messrs. Blanford and Jesse which I have examined. 



This leaves it at present uncertain how far AZgialitis nigris 

 penetrates towards the east of the great African continent. It 

 would be of interest to examine specimens from the Gaboon, 

 where the two species would be expected to meet, but where at 

 present, according to Dr. Hartlaub, only tricollaris has been 

 obtained.
