HEAD and neck blackish-brown, tinged with grey ; back and 

 shoulders of the same colour, each feather tipt with white. 

 Throat black and white ; breast brownish -black ; lower parts 

 white ; tail grey, crossed with broad black bands, tipt with 

 white. Length, 2' 7"; wing, V 9"; tail, 12f". Iris pale 

 straw- yellow 



Rather rare in the colony, frequenting mountain-ravines clothed 

 with timber, and keeping to the same spot for many successive years. 

 Shy and suspicious, it rarely falls before the gun, although no oppor- 

 tunity is lost of killing a bird so destructive to young lambs. 



I saw several pairs on the East Coast of Africa, and shot two at Fazy, 

 a native village within a degree and a half of the Line ; here they 

 seemed quite fearless and allowed an easy approach. Mr. H. Gird, 

 M.L.A , obtained a noble pair on his farm, Oliphant's Fontein, which 

 are now mounted in the Museum. Mr. Atmore writes from Blanco, 

 probably of this species : he says : "I have heard of another eagle 

 inhabiting the forest head, neck, and back blueish, belly white ; but I 

 have not seen him yet. He preys on poultry, monkeys, and cats ! Last 

 week one carried off my hostess's favourite " Tom/' and she now hopes 

 my Tom (his son) will shoot him," so do I ! 



Mr. Henry Jackson has sent an egg of this fine bird from JSTel'a 

 Poort. He says they lay but one in a nest. It is pure white ; Axis, 

 3" 1'"'; diameter, 2" 4'"

Le Vaillant affirms that he found this species in Namaqualand, 

 frequenting rocky, desert places ; and preying on the dassie (Hyrax 

 Capensis). He also states that it is fierce and solitary, building in deep 

 rocky caverns ; the nest a heap of dry branches, on which is massed 

 leaves and moss. Eggs two, rarely three ; and he gives a long account 

 of its habits, painting a wonderfully graphic picture of its ferocity, and 

 the terror it excites amoug the dassies. Unfortunately for M. Le 

 Vaillant's character, it is too probable that the bird only existed in
