butin the plate the peculiar shortness of the tip of the wing is rendered 
very exactly. 
In 1885 (Orn. Expl. Kamtsch., p. 236) I gave the measurements, 
including averages, of six Japanese specimens. They are included in 
the following table, and it is very interesting and gratifying to observe 
how close the averages of the two series run, as the results indicate 
that their figures are worthy of confidence. 
Blakiston (Chrystanth., 1883, p. 35) informs ts that the larks do not 
winter in Yezo. The present species passes the cold season in Hondo.

{ The U.S. National Museum possesses three more adult specimens of Alauda japonica (Nos. 96302, 
96: 308, 96319) which, in view of the above series, it is unnecessary to measure, as they are not sexed by 
the collectors. Three young ones also beloug to the Museum, viz: No. 88657, collected by Mr. Jouy, 
at Fuji, July 22, 1882; No. 96304, Hakodate, June, and No. 96317, Yubutz, September, both collected 
by Capt. Blakiston.

As contended by Capt. Blakiston long ago, there is no difficulty in 
keeping separate the two forms of larks which inhabit Japan, for the 
measurements alone are sufficient to distinguish them, as shown by the 
appended tables of dimensions. 
A. blakistoni is very nearly allied to A. intermedia Swinu. of the 
opposite mainland and to A, arvensis LIN. of Europe, being, in fact,
