Dendroeopus leucoiiotus (Bechstein).

These birds have a little more white on the inner secon- 

 daries than Swedish birds so that the outer black bars are 

 broken up in large black spöts. The lateral tail feathers 

 are not barred by black, but have only one or usually two 

 transverse black spöts on the outer web and three or four 

 on the inner web. Through these characteristics they ap- 

 proach D. leuco. cirris, Pallas or uralensis Bonaparte, but 

 they are by far not so white as typical specimens of this 

 variety. Already specimens from Finland have more white 

 than Swedish specimens and almost as much as these two. 



BuTURLiN has recently described a subspecies of the 

 White-backed Woodpecker from the , »southern parts of 

 Ussuriland (Sidemi) »which he has named D. 1. ussuriensis. 

 This shall be distinguished by its forehead being »richly 

 tinged with ruf ous-brown » or »chestnut». The specimens 

 of this collection have the forehead isabelline white and are 

 thus quite different from Buturlin's subspecies. 



Dendrocopus minor (Linnaeus). 



Kiret 9 (n:o 124) ^Vc 1908. 



This specimen agrees with D. m. pipra (Pallas) having 

 the lower back white without black bars and the white bars 

 on the wings somewhat broader than in Swedish specimens 

 with which it otherwise agrees. The lower side is bro wnish white. 

 The most conspicuous difference from Swedish specimens 

 is that the bill is decidedly more slender with concave lateral 

 contours when viewed from above. This feature is of some 

 importance when compared with the fact that Dendrocopus 

 major from this region also has a^ thinner bill than typical 

 specimens. The material is not sufficient for expressing 

 any definite opinion about this bird, whether it represents 

 a separate geographic race or not. The slenderness of the 

 bill of this as well of D. major stånds, of course, in connection 

 with some habits of these birds. The bilis of the Swedish 

 Woodpeckers are evidently subjected to being used as tools 

 for härd work hammering and chiseling in wood more than
