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 9 , 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.
