 Sharpe, Cat. Ace. I, p. 342. 



A fine pair, male and female, of black hawks belonging to 

 this species were procured on the Laloki River, on October 16, 

 1877. No information on their habits or nidification was 

 obtained. 



There is no sign of a crest of any kind on either specimens, 

 otherwise they resemble M. alcinus, ( Western) in having the 

 abdomen and flanks brown — with the base of the feathers white. 

 There is however a distinct white collar on the back of the neck, 

 the feathers on the central portion of the collar tipped with 

 black. The feathers of the head, neck, shoulders, and inter- 

 scapular regions are chiefly black ; throat white, with a blackish 

 patch on either side, and a stripe of black down the centre; lower 

 portion of the chest white in the centre, the upper portion 

 mottled with black and white ; legs and feet bluish grey, bill 

 black, iris yellow, J" total length 17 "3 inches, wing 13 '2, tail 7 "3, 

 tarsi 2*1 ; middle toe 1*7, its nail 0/, slightly serrated at the 

 base of the inner margin ; hind toe 0*8, its nail 1 inch. $ total 

 length 17 inches, wing 128, tarsus 2*3, bill from forehead 08, 

 from gape 1*5, culmen 0*9. The female in this instance, contrary 

 to what I expected, is slightly smaller than the male.

 inland on the Laloki. The rufous tint on the side of the neck is 

 not continued on the back of the neck ; there are other minor 

 differences which can scarcely be specific. The back is of a
