Ithagenes sinensis michaelis Bianchi 



Type. — "River Chycho, Northern Nanshan Mountains," Bianchi, Ann. Mus. Zool. l'Acad. St. Petersb., VIII. 

 1903, p. 1. Type is in the Petrograd Museum. 



Geographical Distribution. — Northern slope of the Nanshan Mountains. (It has been found on the 

 Baboche River, a branch of the Edzingol, and by Grum-Grzimailo on the Chycho.) 



Subspecific Characters.— Male : Wing-coverts pale golden-yellow (not cinnamon or chestnut) with 

 decided mingling of green. The same hue appears well developed on the light shaft-stripes of the lower 

 interscapular region, while it is the dominant colour of the entire stripe on the shoulders, back, rump and upper 

 tail-coverts. General tone of coloration very plain. Size large, the wing measuring 226 mm. 



Female : Sides of the neck grey (not cinnamon); hind neck and occipital crest uniform grey; plumage of 

 under parts pale chocolate (not chestnut or cinnamon) brown. Coloration in general paler. No traces of crimson 

 on tail feathers. Largest of the three forms, the wing measuring 203-210 mm. 



A single male bird was collected by the Grum-Grzimailo brothers north of the 

 principal Nanshan mountain range. This individual is larger and paler than the Blood 

 Partridge from the southern slopes and shows so much greenish on the plumage of 

 the mantle and lower back that this hue is quite distinguishable in the living birds 

 when seen from above. This bird was named by Dr. V. Bianchi after one of the 

 collectors.
