the Birds of Chinkiang. 3 
be distinguished from G. canus by the presence of a few black 
marks on the crown and nape. 
Considered as a whole, however, the Fohkien birds are 
quite distinct from the Chinkiang birds, just as taken col- 
lectively Gecinus guerint is distinct from G. canus, and 
G. tancola of Fohkien differs from the southern G. occipitalis. 
This is proved by my series of Green Woodpeckers from 
Fohkien and Chinkiang. 
Nearly every specimen of G. guerini obtained by me at 
Chinkiang is noticeably lighter in colour than those from 
Fohkien. The upper parts in Chinkiang birds are of a lighter 
green, often with a wash of grey, and the lower parts are 
yellowish grey-green in place of the darker green of the 
southern birds. The malar stripe is almost invariably smaller ; 
in the female sometimes almost absent. In the male the 
crown behind the red patch is grey, streaked, generally very 
lightly, with black, and the nuchal spot is seldom so extensive 
as in Fohkien birds, being sometimes very small and brown- 
ish in colour. One bird shot on April 21 has a large black 
nuchal patch as in specimens from Fohkien, but there is 
hardly any black round the red patch, and the under parts 
resemble those of the normal Chinkiang bird. In the female 
the difference is still more strongly marked. The general 
coloration is very much lighter, the moustache is very slight, 
the head is greenish grey lightly streaked with brownish or 
black, and the nuchal patch is small. There is generally a 
trace, often well marked, of obsolete bars on the secondaries. 
In one of my female specimens from Chinkiang, which is 
dated November 17, there is no proper nuchal patch, only a 
few feathers of the nape being brownish black. In another, 
dated December 30, the crown is but faintly streaked and 
the nape-feathers are tipped or centred with brownish black ; 
while the malar stripe consists of two or three blackish 
feathers. 
The average Chinkiang bird is therefore typical G. guerini 
Malh., but specimens are obtained in this locality which 
intergrade with the northern G. canus, and sometimes, but 
more rarely, we find others which come very close to the
