ACCIPITER RUFIVENTRIS. 
same size and figure as the male, lettered A, and already described ; the 
colours are as follow : — 
The upper parts, comprising the head, neck, interscapular, back, upper 
tail coverts, and lesser wing coverts, intermediate between brownish red and 
lavender-purple, to which is superadded a distinct gloss of the lattei , the 
shoulder feathers are faintly edged with pearl-grey. The quill and scapular 
feathers coloured as in the specimens already described. The bars of the 
tail, so far as the numbers are concerned, are also similar, but the light 
coloured ones have superiorly a greyer tint, and the portion of shaft between 
them is of a clearer white. The ear coverts, sides of the neck, lower part of 
the throat, breast, belly, and thighs, clear reddish orange, without variega- 
tions ; upper parts of throat yellowish white ; under tail coverts pure white. 
Colour of legs, toes, claws, bill, and eyes, as in the specimens described. 
This species occurs, though sparingly, in all parts of the Colony, and specimens are 
not uncommon near to Cape Town and towards the sources of the Great Fish river. It 
resembles in its habits the common Sparrow Hawk, and its chief food consists of small 
quadrupeds and birds. The majority of the specimens which I have had the opportunity of 
examining, exhibited the colours of the specimen lettered C.
