THE TRUE PHEASANTS, 7 
6. With a broad white ring round the neck 
(species 8, pp. 22-24). 
£. General colour of the lower back, rump, and upper tail- 
coverts greenish- or bluish-slate colour, with a rust- 
coloured patch on each side (except in P. vers;- 
color). 
¢. With a white ring round the neck (species 
9 to II, pp. 24-28). 
ad, With no white ring round the neck, or with 
only traces of one (species 12 to 16, 
pp. 28-33). 
II. Crown of the head reddish-brown (species 17, pp. 34-37). 
IIT. Crown of the head white (species 18, pp. 37-41). 
BothScemmerring’s and Reeves’s Pheasants represent peculiar 
and somewhat aberrant types, the latter being placed by some 
authors in the distinct genus Syrmaticus, on account of its 
immensely long tail. Exclusive of these two birds and the 
rather distinct green-bellied form (P. versicolor) from Japan, 
the remaining representatives of the genus Phaszanus are all 
birds of the same type as the Common Pheasant (P. colchicus). 
It is interesting to note that, roughly speaking, all the species 
with white rings round their necks are northern forms, while 
those without this ornament, or with only traces of it, are only 
met with farther south. On the other hand, all the maroon- 
rumped species are found west of about go” E. long., while 
those with grey rumps are only found to the east of this 
line. £P. colchicus and its allies, which have no white ring, 
but have a maroon-coloured rump, inhabit the area south 
of about 41° N. lat., and west of about 80° E. long., while 
P. mongolicus and P. semttorquatus, both of which have well- 
marked white collars, as well as maroon rumps, are met 
with north of about 41°, and west of about go° E. long. 
Again, among the grey-rumped species, P. elegans and the
