18 BULLETIN OF THE LIVERPOOL MUSEUMS. 
Singapore, which, we presume, would be considered typical 2. calonyx, has the 
wing 7°5 and the whole of the terminal portion of the tail markedly washed with 
deep ultramarine blue. As regards the colour of the outer secondaries, which 
is also made a diagnostic character by Dr. Sharpe, the Singapore specimen has 
the outer webs uniform deep ultramarine blue ; the Labuan specimens collected 
in October and December have a narrow edging of the same colour; the adult 
Chinese specimen has none whatever, and it is narrower and paler on one of the 
immature Chinese specimens though much more marked in the other. When 
such variation is observable even in a limited series it seems advisable, at any 
rate for the present, to include #. ca/onyx and #7. wtor under L. orientalis. 
Messrs. Meyer and Wiglesworth (Birds of Celebes i. p. 312), even include JL. 
pacificus under the same heading.

It is difficult to decide to what species the specimen from Honduras should be 
assigned ; the general colour of the crown approaches M. cewruleiceps, but the 
centre is black like MZ. lessoni ; the colour of the under surface is more rufescent 
than either W/. lessoni or M. cwruleiceps, in this respect approaching WM. swainsoni.
