INSESSORES. 461 



bold and pugnacious, the young males particularly so. In 

 confinement several cases have occurred of one having killed 

 the other. The young males closely resemble the females in 

 plumage during their first year, in the second they partially 

 assume the gay plumage of their sire, and in their third year 

 they put on the full livery of the adult male." 



The male has the head and back of the neck, running in a 

 rounded point towards the breast, rich bright gamboge-yellow, 

 tinged with orange, particularly on the centre of the forehead ; 

 the remainder of the plumage, with the exception of the se- 

 condaries and inner webs of all but the first primary, deep 

 velvety black ; the secondaries bright gamboge-yellow, with a 

 narrow edgnig of black along the iimer webs ; the first primary 

 is entirely black, the next have the tips and outer webs black 

 — the half of the inner web and that part of the shaft not 

 running through the black tip are yellow ; as the primaries 

 approach the secondaries, the yellow of the inner web extends 

 across the shaft, leaving only a black edge on the outer web, 

 which gradually narrows until the tips only of both webs 

 remain black ; bill yellow ; irides pale yellow ; legs and feet 

 black. 



The female has the head and throat dull brownish white, 

 with a large patch of deep black on the crown ; all the upper 

 surface, wings, and tail pale olive-brown, the feathers of the 

 back with a triangular-shaped mark of brownish white near 

 the tip ; the under surface is similar, but here, except on the 

 breast, the white markings increase so much in size as to 

 become the predominant hue; irides brown; bill and feet 

 black. 



Genus MIMETA, Vigors and Horsfield. 



This form is merely an offshoot from Oriolus, from which 

 it is distinguished by the absence of any gay colouring in 

 the plumage of its members. Three species inhabit Australia,
