All these speeimens are mentioned, because Dr. Sliarpe 

 liad plaeed those collected previously to the writing of his 

 papers under T. nitens. Others given in his papers under 

 7\ 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 eti'ort to 

 reconcile the specimens with the wrong descriptions. 



The iris and the feet in T. nigro-mitrutus are coloured as 

 in T. nitens, but the bill is entirely black. 



The young bird (No. 42G7) 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. 42G6.
