2. Uragus sibiricus fumigatus, subsp. nov. 
A large bird, generally considerably darker, more smoky 
than U. s. sibiricus, otherwise much like the latter. 
Its habitat includes the upper basin of the Yenesei, the 
Irkutsk region, eastward to the Amur divide, and southward 
merging into that of U. s. stbiricus somewhere near the 
Siberian and Mongolian frontiers. 
3. Uragus sibiricus ussuriensis Buturlin. 
Uragus sibiricus ussuriensis, Buturlin, Messager Ornithol. 
vi. p. 128 (1915). 
A smaller, more intensely coloured bird with less white on 
the wing, the white on the outer web of the secondaries con- 
siderably less than in U. s. sibiricus and fumigatus. 
Its habitat is the whole of the Amur and Ussuri basins, 
extending throughout Manchuria into Corea and neigh- 
bouring North-eastern China, and probably northward to 
include Kastern Siberia, merging into the habitat of U. s. 
fumigatus on the western rim of the Amur basin, and possibly 
meeting that of U. s. sibiricus in North-eastern Mongolia. 
4, Uragus sibiricus sanguinolentus (Temminck & Schlegel). 
Pyrrhula sanguinolenta T. & 8. Faun. Jap. Aves, p. 92, 
pls. 54 & 545 (1850). 
A still smaller, very intensely coloured island form, to 
which specimens taken on the mainland have usually been 
referred, but which is certainly distinct. Measurements 
of the wings of series from the Islands of Saghalin, Yeso, 
and Japan, compared with the same of a series from the 
mainland show that the island birds run in a series from 
65 to 69 mm. in the males, and 60 to 64 mm. in the females; 
while those from the mainland run in a series of 65 to 73 
mm. in the males, and 62 to 69 mm. in the females. Records 
of sanguinolentus from Corea and Peking (David) must be 
considered to refer to Buturlin’s wssuriensis, unless, indeed, 
it be found that yet another form occurs in Nortli-eastern 
China, South-western Manchuria, and Corea. 
The habitat of true sanguinolentus is Saghalin Island, 
the Japanese Islands, and possibly the Kuril Islands.
