Further account of the cai)ture would be highly iuterestiu}^, espe- 

 cially whether it was found alone or in company with others of the 

 same species. 



(10 li) Triuga canutus L. 

 No. 306, a young bird, is from Tokio, without further information, 



Tringa ferrugiuea JJruxn. 



From the fact that this species (also known as T. snharquata) has been 

 recorded from the Tchulcchi peninsula, it was to be exi)ected that it 

 would turn ui), occasionally at least, in Japan during the migrations, 

 though, on the other hand, the circumstance that it had hitherto not 

 been observed, ueither in Kamtschatka nor in Japan, makes it safe to 

 conclude that its regular migration route does not lie so far east. 



Two specimens (Nos. 298 and 293), both from Giotoku, prove that 

 it occurs both on the spring migration and in the autumn, and from the 

 superticial resemblance to 7\ alpina paciUca [T.vinclus) it is i»robably 

 often mistaken for the latter. The lirst one is a tine adult male in 

 splendid summer plumage, collected ]May 23, 1884 ; the, (tther is a young 

 bird in the first fall i)lumage, obtained September 20, 1883. 



T. ferrugiuea is easily distinguished from T. alpina by the bill being 

 much narrower at the tip, by the white upper tail-coverts, and, in the 

 summer plumage, by having the under surface rusty or chestnut, while 

 in T. alpina these parts in summer are white with a large i^atch of 

 blackish on the belly. 



(108) Triuga acuminata (HoRSF.). 



No. 291, S ad., collected at Horiye, province of Musashi, Hondo, 

 July 27, 1883, is particularly interesting inasmuch as it is in full breed- 

 ing plumage considerably abraded. In this plumage, the first I have 

 ever seen, the bird looks very dilferent from the winter plumage in 

 which it is usually found. The under parts are much more densely 

 spotted, and the yellow tinge of the fore neck is moreochraceous, while 

 the broad rusty edges of the feathers on the upper parts are nearly 

 gone. 



The breeding grounds of this species have not yet been ascertained 

 with certainty,* and although the occurrence of this bird in the plum- 

 age here described in Jai)an on July 27 would seem to indicate that it 

 may breed there, at least occasionally, yet it is well known that non- 

 breeding individuals of m;uiy waders remain during summer in a much 

 more southern latitude than the regular breeding grounds. 



Seebohm (l)istr. Charadr., p. ii'J) refers Latham's Tringa aurita to 

 the present species without even a query, but Latham's description
