Woodpecker with its thick and stumpy bill at the same 

 time has the nasal plumes or bristles much more strongly 

 developed than the Mongohan, and I have stated that this 

 is a constant characteristic in all specimens examined. 



With regard to the slender bill and the comparatively 

 scanty developement of the nasal bristles the Mongohan 

 Woodpeckers resemble Picus major japonicus f . i. from Sagha- 

 hn. The latter is, however, a conspicuously smaller bird 

 in every respect. The length of the wing in these Mongo- 

 han specimens varies from 137 to 141 mm, while the same 

 measurement in Saghahn Woodpeckers is from 128 to 131 



mm. 



It is evident from the description above that this Mongo- 

 han W^oodpecker has nothing to do with Severtzov's »Piciis 

 leptorhynchus»^ (already before named lecopterus by Salvadori 



1870 71) from Turkestan in spite of its slender bill because 



the distribution of the white on the secondaries etc. is as in 

 the typical D. major. 



In the Cat. Birds. Brit. Mus. Vol. XVIII p. 203 it is 

 stated about the group to which the typical Dendrocopus 

 major belongs in contrast to D. japonicus, that in the former 

 »innermost secondaries are uniform black.» This is not 

 correct. The innermost secondary is sometimes quite 

 unspotted but the one next seldom if ever. The condition 

 found in a number of specimens examined may be seen from 

 the following table
