It is a very difficult task to locate properly the different quotations 

 pertaining to the Japanese Marsh-tits, without access to the specimens 

 upon which they are based. The above synonymies, therefore, do not 

 claim to be absolutely correct, and may in time require to be consider- 



minor, for that matter. LatLiam (Syuops. II, ii, p. 542) describes his birds as " «o< 

 having a Mack chin, all the under parts btiug \yhite. One st'X had the whole head 

 black, with a baud of white across the hind head; in the other, only the fop of the 

 head was black, and the nape yellowish." The Latin description in the subsequent 

 "Index Ornith." (II, p. 566) is substantially to the same effect. Stephens, on -he 

 other hand (7. c), in his diagnosis of Parus japonieus, says : " Titmouse with a hlaek 

 hearl and throat," and in the description: "differs chiefly in having a hlaek chin and 

 colored nape; all the rest of the under parts of the body white." Had Stephens's de- 

 scription been based upon the specimens themselves, there might have been reasons 

 for supposing the bird to be P. minor; but as it appears that he has only made a slip 

 in rendering Latham's description, the name must remain unidentified. 



At any rate, Seebohm's Parus japonieus will have to be renamed, should it later 

 on be found necessary to keep the bird, separated by him, apart from the true borealis.
