oy4 REVIEW OF JAPANESE BIRDS. 



APPENDIX TO THE MARSH-TITS (see autea, pp. 378-382). 



Since the above was written and transmitted for publicatioa I have 

 had an opportunity of examining- some additional and very valuable 

 material, which Mr. Henry Seebohm has had the kindness to send me for 

 inspection, a courtesy for which I hereby render my sincere thanks. 



Besides two specimens of Parus songarns Seveez., which present the 

 ap])earance of a very marked species^ and a specimen of a Marshtit from 

 Pekin, collected by Mr. R. Swinhoe, which is very much like the Eu- 

 roj^ean forms P. palustris and dresseri, though lighter a!id clearer than 

 both, and differing from them in about the same degree as does P. baica- 

 lensis from P. horealis, the collection sent by Mr. Seebohm contains two 

 typical P. horealis, two P. baicalensis from Krasnoyarsk, two P. brevi- 

 rostris from Amur, and two specimens from Yesso, which appear to be 

 the types upon which, in 1879, Mr. Seebohm based his P. japonicus. 

 One of these is Whitely's No. 97a, the other Blakiston's No. 1121. 



These two specimens confirm the opinion expressed by me, that the 

 name P. japonicus belongs to the Yesso bird. They agree in every re- 

 spect with the two northern specimens in the National Museum (Nos. 

 96144 aud 9014:5) not only in coloration, but also in the size of bill 

 aud tail. The two P. brevirostris of Mr. Seebohm's collection ( S and 

 9 , collected in April; without numbers) differ only in having a much 

 shorter bill; in other respects they are identical with the Yesso birds; 

 but from our experience with the European forms we are not inclined to 

 lay much stress upon this apparent difference, and unless large series 

 of specimens from the two countries should prove the size of the bills 

 to be a feature generally separating them, the Japanese form will have 

 to stand as Parus brevirostris. 



The Japanese birds agree with P. baicalensis in regard to the size of 

 the bill, but the latter is considerably grayer on the back, and the black 

 cap is more brownish. 



I take the opportunity to present a new table of measurements of 

 Parus brevirostris including Seebohm's specimens from Yesso and Amur, 



Measure7nents.
