186 SOME CHINESE VERTEBRATES. 
Characters: —Similar to true S. modestus Burton of the Himalayas, but 
much grayer, and less greenish in color throughout; upper parts dark, grayish ~ 
olive-green, much darker, more grayish, less brownish than in true S. modestus; : 
under parts dull, grayish pea-green, very different from the pale yellowish olive- — 
green under parts of true S. modestus. 
Measurements: — Type adult 2, wing, 54; tail, 51.5 ; tarsus, 15; culmen, 7. 
Remarks: — Although we have but a single example this is so different in 
general color from Himalayan skins that it represents without doubt an easily 
recognized Chinese subspecies. 
SITTIDAE. 
SITTA SINENSIS Verreaux. 
Twelve specimens, adults of both sexes from Ichang, Kwatzeling, Fonghsien, 
Putze, Hsienshanhsien, and Changyanghsien, Hupeh in altitude up to 6,500 feet, 
all seasons. 
Sitta MontiuM La Touche. 
Five specimens, four adults of both sexes and one young, Nachuka, 12,000 
feet, Ramala Pass, 12,000 feet, and Yachow, western Szechwan, midsummer. 
The differences, as pointed out by La Touche, distinguish a mountain from 
a lowland form of the Chinese nuthatch stand out so strongly in our series and 
are of such a nature that taken together with the distribution, would indicate 
specific rather than subspecific rank for the two forms. 
SITTA PRZEWALSKII Berezowski & Bianchi. 
One adult female shot Aug. 18, 1908, at Shuowlow, western Szechwan, 
14,000 feet. 
This specimen, though a female has a wholly blue-black crown and agrees 
minutely with the original description of the type, an adult male. 
CERTHIIDAE. 
CERTHIA FAMILIARIS KHAMENSIS Bianchi. 
One adult ~@, Lianghokow, western Szechwan, 13,000 feet, September 7, 
1908. This specimen in fine fresh plumage, apparently belongs here, and is not 
referable to C. familiaris bianchii Hartert recorded from northern Szechwan.
