More remarkable still is the occurrence at Gambaga of some species only known 

 from Angola to Nyassa-land — i.e., Accipiter oram/je/i.tis (Xo. 3(i), Petroclielitlon 

 ••ujigula (No. Ifio), and a I'onn closelv allied to' Bessonornia modestus Shelley 

 (No. 1129). 



The occurrence of such forms within the bend of the Niger is quite unexpected, 

 and it shows how little we know of the details of distribution of African birds. 



In addition to thirty-four of the forms collected by Captain Giflard, the 

 following were obtained near Gambaga by Colonel H. P. Northcott : 



ilacindipter>/x macrodipterus, La/iius gubernator (previously only known from 

 Eastern E<piatorial Africa), Prioimps poliolophus, Pijtelui kijpog ram mica, Crateropiis 

 reinwardti, according to Sharpe in Bull. B. 0. Club, vol. x. pp. 6, T, October 1899. 



LIMICOLAE. 



1. Oedicnemus affinis Rttpp. 



<J Gambaga, 20. 12. 1898. " Iris yellow." 



The distribution of this species is generally only known to be North-east 

 African. In the Catalogue of Birds (vol. sxiv.), it is given as: "North-eastern 

 Africa, from Kordofau and Bogos, south to Somali-land, and to Lado in Equatorial 

 Africa." 



2. Pluvianus aegyptius (L.). 

 ? Gambaga, 27. 10. 1898. "Iris brown, legs grey." 



3. Gralachrysia cinerea (Fraser). 



? Gambaga, 27. lu. 1898. " Legs and base of bill coral rod." The base of 

 the bill is not yellow, as stated in Cat. B. Brit. Mas. vol. xxiv. p. 65. See also 

 Joarn.f. Orn. 1880, p. filo. Dr. Sharpe recorded this species from the Rio Volta, 

 Prof Reichenow from Togolaud. I found it far in the interior of Haussalaiid, to 

 at least 12^ north. Gambaga seems to be the most westerly locality known for 

 tliis bird.

ft. Lobivanellus albiceps (Gould).
