tVoni Jai)an, but there is scarcely any ditVcrence at all to be seen 

 in most cases, although the Saghalin birds are sometimes a little 

 greener on the head than some Japanese specimens, while the 

 latter may have the mask a little blacker. 



5 eggs in a sot were collected by Professor Iji:\rA's ex- 

 pedition at Treti^-a Padj on the 10th of June. The species 

 was one of the commonest birds observed along the shores of 

 Lososoi and Aniwa Bays during the party's stay.

All these specimens are so large and have such long wings 

 that I must refer them to Alauda arvensis pekinensis rather 

 than to A. a. japonica. The specimen collected on July 25th has 

 the length of wing not longer than 108 mm. in the actual state, 

 but the plumage is so much worn that it may be regarded 

 for certain that the wing in the fresh state of the quills must 

 have measured at least 110 mm. The measurements taken from 

 other specimens are : in three 111 mm., in one 112, in four 113, 

 in two 114, in one 115, and in still another IIG mm. The length 

 of bill varies from 14 to 12 mm. The length of hind claw is 

 extremely variable, ranging from 10 to 23 mm.
