neck and mantle. The crown is clear chromium-green 

 instead of olive-green ; the superciliary stripe is twice as 

 broad and snow-white instead of greenish huffy white. The 

 most striking difference, however, is in the feathers of the 

 upper rump and lower back. In P. torquatus these have a 

 sub-terminal, oval, transverse, and narrow bar of green, then 

 one of huffy grey, then a more or less interrupted one of 

 black, and, lastly, a black longitudinal centre with the pale 

 space on each side vermiculated with black. In P. hagen- 

 becki these feathers have a creamy-white ground- colour, two 

 green entire transverse sub-terminal bauds, and theu two 

 smoky-black transverse bars across the middle portion of the 

 feather. This gives the lower back and rump a much more 

 mottled appearance in P. hayenbecki, which has also the lower 

 and greater wing-coverts clearer blue-grey. The front of 

 the neck and the sides are oily green instead of purplish 

 blue washed with oily green. Wing 26 cm., tail 51 cm.

" I must now revert to Phasianus torquatus, Gm. I find 

 on examination two decidedly marked races of this Pheasant, 

 which will apparently have to stand as follows : — 



" Phasianus torquatus, Gm. South China. 



iC Phasianus torquatus mongolicus (Pall.). N.E. Mon- 

 golia, Amur, and Corea. 



"This latter form diffeis from typical P. torquatus in 

 several particulars. The crown and occiput are olive-brown 

 instead of olive-green ; the superciliary stripes are very 

 broad, uniting on the forehead, and of a brownish buff 

 colour mixed with buffy white, instead of greenish whitish 

 buff; the hind-neck and mantle have the feathers darker, 

 more golden buff, with a nearly complete green collar below 

 the white ring, this collar being absent in the typical form. 

 The flanks are darker buff, the breast-feathers having the 

 violet borders much narrower or almost obsolete. The rump 

 is brownish olive instead of greenish lavender-blue, the sides 

 of rump being more of a dirty orange colour. The broad 

 borders of the scapulars are duller chocolate-red.
