All these specimens are mentioned, because Dr. Sharpe 
had placed those collected previously to the writing of his 
papers under T. nitens. Others given in his papers under 
T. nitens are not now in the British Museum. This species 
is the darker-coloured and bluer one, with but little crest 
and a shorter tail. There is no difference between the sexes 
as regards plumage ; females are slightly smaller than males. 
Immature birds may be known from the plumage only by 
the fact that the black of the crown is not so deep, and 
even the very young bird mentioned above is of the same 
general colour as the adults, though the head is only dull 
slaty black, and the back dull dark grey, not bluish. 
This species and T. nitens are very distinct, and are 
distinguished by Dr. Sharpe. But in some unaccountable 
way he got the names transposed ; and his remarks shew 
a confusion apparently caused by a subsequent effort to 
reconcile the specimens with the wrong descriptions. 
The iris and the feet in T. nigro-mitratus are coloured as 
in T. nitens , but the bill is entirely black. 
The young bird (No. 4267) had the inside of the mouth 
and tongue bright orange, unmarked, and the margin of the 
gape pale yellow. It was shot with bow and arrow along 
with No. 4266.
