160 SOME CHINESE VERTEBRATES. 
PICIDAE. 
Picus CANUS GUERINI (Malherbe). 
Thirty-six specimens, both sexes, Ichang, Ichanghsien, Changyanghsien, 
Hochaping, Yangtze near Shasi, Kunganhsien, Ituhsien, Putze, Hsienshan, 
Omeihsien, Shaiyiiehtze, and Hsienshanhsien, Hupeh, and Cheto, western 
Szechwan, all seasons. 
Not one of these numerous skins, can be referred to Picus occipitalis (Vigors) 
though many approach it. Two skins from Cheto, for instance that on geo- 
graphic grounds might be expected to be occipitalis have the completely barred 
tail of guerini, but they also have almost wholly black bills, the yellowish 
green of the lower mandible, so conspicuous in P. guerini, being restricted 
to a small spot near the base. Other specimens from Hupeh, occasionally 
show almost wholly black tails, but invariably have the yellowish lower man- 
dible; and there is not one in the series that combines the black unbarred tail 
with the black bill. 
HyPpoPpicUs HYPERYTHRUS SUBRUFINUS (Cabanis & Heine). 
Two adults, male and female, Tachienlu, July 7, 1908, and Nochiang- 
hsien, Szechwan, April 23, 1908. 
This species is very rare in the region under consideration; one other 
individual was shot but not secured. 
DRYOBATES CABANISI CABANISI (Malherbe). 
Thirty-six specimens, young and adults of both sexes, Ichang, Hsienshan- 
hsien, Chiliping, Shihtowya, Changkowhsien, Ituhsien, Changyanghsien, and 
Ichanghsien, Hupeh, and Wulungshih, Shuowlow, and the Ramala Pass, Sze- 
chwan, all seasons. No variation in any way correlated to altitude or locality 
in this large series can be traced; skins from Ichang being, on the whole, 
similar to those from western Szechwan at 15,000 feet. Individual variation 
in the color of the under parts, the color and width of the frontal band, the in- 
tensity of the red of the belly and under tail-coverts, and other minor points, 
is very great. The white marking, on the inner secondaries also varies some- 
what. 
DRYOBATES PERNYI PERNYI (Verreaux). 
Two adults, a male taken at Changyanghsien, Hupeh, January 24, 1909, 
and a female shot at Wantaoshan, Hupeh, June 5, 1907.
