539. ACCII'ITER MINULLLTS. 



CC. Knysna, Feb. (1) ; Plettenberg Bay, Mcli. (1) ; 

 P. Coguno, Aug. (1) ; Tete, Sept. (1). 



The two adult males from Coguno and Tete are markedly 

 paler than the Knysua example, which might be described 

 as black above^ while the Portuguese specimen is slaty- 

 blue. 



This species is very poorly represented in the British 

 Museum, but there are four adults from Natal which are 

 nearly as dark as the Knysna bird, while a few examples from 

 East Africa are rather paler, but none of them contrast quite 

 so strongly as those in the present collection. This may be 

 due to the existence of a dark and light phase, or there may 

 be a geographical or possibly seasonal variation ; the material 

 at hand is not sufficient to decide the questiou. 



[This little Sparrow- Hawk has been noted in Zululand, 

 the Knysna district, the Transvaal, and the Inhambane and 

 Tete districts of Portuguese East Africa. It is a Hawk of 

 the forests and Avell-wooded country, and in flight and habits 

 much resembles A. nisus. 



The soft parts are : — Ad. Irides yellow ; cere, round eyes, 

 and legs and toes yellow. Jiw. Irides dirty yellow ; cere, 

 legs, and toes greenish yellow.] 



510. AcCIPITER RUFIVENTRIS. 



Tv. Zuurbrou, jNlay (1). 



[Although I only observed this species in the locality 

 the specimen comes from, it must exist in every Avooded 

 country that I visited, and no doubt I liave mistaken it for 

 Astur iachiro, to which species, except for the fact that it 

 does not soai', it is similar in flight and general habits. 



The soft parts are : — Irides bright yellow ; cere greenish 

 yellow ; bill pale slaty at base, dark at tip ; legs and toes 

 bright yellow.]
