292 MR. R. SWINHOE ON THE BIRDS OF CHINA. [June 23, 



regularly migrate. I found them not uncommon about Canton. I 

 have procured them at various seasons at Amoy, and have seen them 

 from Tientsin. 



153. Larvivora sibilans, n. sp. 



Larvivora, sp. ?, Swinhoe, Ibis, 1861, p. 34. 



My only specimen from Macao of this bird is a very wretched one. 

 It may be that of a female, but I have reason to believe it an adult 

 bird ; for I watched several, and they all appeared of similar plumage. 

 It is of a sober olive-brown, with the red tail of a Redstart, the feet 

 of Larvivora, and the bill of a Robin. It was not at all uncommon 

 about the copses and thickets near Macao in May, but extremely 

 difficult to get at. I trust I may make the bird's better acquaintance 

 on some future day. I have thought it worth while now to allude 

 to it, as I consider it a good species. 



154. Calliope kamtschatkensis, Gm. 



Male with fine crimson throat. Females with throat whitish, 

 and without the white and black that ornaments the face of the male. 

 When passing our coast in spring, the young males are found re- 

 turning without having acquired the adult tints, usually only a few 

 reddish feathers appearing on the throat ; but the change of hue 

 (not moult) goes on very rapidly, and probably would be perfected 

 by the time of their arrival at their northern destination. The 

 young males can be readily distinguished from the females by their 

 much whiter throats and darker lores. These birds touch at Amoy in 

 their northward migrations in April ; I would hence infer that they 

 had been a long way south for their winter. Their summer range is 

 all through North China, Mantchuria, as far as Kamtschatka. I 

 found them at Pekin in October ; but they were young birds, and 

 might have been late in their southward migrations. They occur 

 abundantly, I am told, during winter in Hindostan. These would 

 be birds from the Siberian region. Our northern migrants would 

 be expected to winter in Siam and the Malayan peninsula, whence, 

 I believe, specimens have been received. In form these birds are 

 intermediate between the Robins and the Reed- warblers. 



155. Tribura sqtjameiceps, n. sp. 



Allied to Tribura luteiventris, Hodgs., from Nepal. I have only 

 one specimen, procured by Captain Blakiston at Canton. Upper 

 parts rich brown, with a tint of chestnut and olive, the former 

 strongest on the head and wings. A well-defined cream-coloured 

 eyebrow runs over the eye. The feathers of the head edged darker, 

 giving the appearance of scales ; under parts white, with an occa- 

 sional tinge of buff; axillaries and flanks olive-brown; wing 2*1, 

 short and rounded, the fourth quill being the longest, the third and 

 fifth ^th shorter, and nearly equal. The specimen is unfortu- 

 nately tailless, and I therefore cannot give a very detailed description 

 of it.
