Mr. Sowerby's collection there are two adult males from near I-mien-po 

 (near Ninguta), N. Kirin, Manchuria, taken in October, that I refer 

 to T. b. septentrionalis . They are very much alike and differ from 

 T. b. vicinitas in being darker gray above, the black barring upon 

 the mantle more pronounced, in having a bare indication of the white 

 scapular bar, and the barring below heavier. A female specimen from 

 the Valley of the Yenesay, Lat. 66)4°, seems to represent still another 

 form, grayer than T. b. bonasia with more white spotting upon the 

 scapulars and wings and the bars below darker and much more num- 

 erous. This Yenesay specimen is much nearer T. b. vicinitas than T. b. 

 bonasia but differs from the former in not having so much white on the 

 scapulars, the barring below more pronounced, and the bill smaller. 

 Possibly it may represent Tetrastes orientalis Madasasz.* 



"Whenever a large series of these grouse from the various parts of its 

 range can be got together and thoroughly studied, some interesting 

 results are to be expected. 



The following are the measurements of the series before me for com- 

 parison :

Three males, Europe 169.2 116.8 15.7 



Two males, Manchuria t 161.5 110.2 16.7

Dryocopus martius silvifragus subsp. nov. 



Type, U. S. National Museum, No. 120,551, adult male, Hakodate, 

 Yezo, Japan, December 2, 1884. Collected by Harry V. Henson. 



Similar to Dryocopus martius reichenowi Kothe, + but black, not so 

 slaty and bill smaller. Wing, 243; tail, 190; culmen, 62. 



Remarks. — I have compared the Japanese bird with a male from I- 

 mien-po (near Ninguta), N. Kirin, Manchuria, and a female from Hsing- 

 lung-shan, 65 miles northeast of Peking, China, and a series of eight 

 specimens from Europe. Hartert |1 unites D. m. reichenowi with D. m. 

 martius but, in my opinion, is not justified in doing so, as the former is 

 a much larger bird in all its measurements and is also of a deeper slaty 

 black. The Japanese specimens have a brownish cast to the black, 

 especially noticeable upon the wings, but this is due most probably to the 

 length of time the birds have been in the collection, as Doctor Stejnegeriji 

 in reporting upon them says they were of a " very intense black." The 

 two specimens of D. m. reichenowi before me are of a very deep black
