Like the Indian black-backed M. alboides {leucopsis, Gould, lu- 

 zoniensis, auct.), but with the pectoral black, in summer plumage, 

 advancing higher, to within half an inch of the lower mandible. 

 Southern China and Formosa. 



Var. 2. skchuenensis, Swinh. P. Z. S. 1870, p. 122, fig. 2. 



The pectoral black in summer reaching to the lower mandible. 

 Szechuen (W. China).

 Mongolia. Forwarded to Paris by Pere David. 



193. Motacilla hodgsoni, G. R. Gray; Blyth, Ibis, 1865, 

 p. 49. 



Motacilla francisci, Swinh. P. Z. S. 1870, p. 123; Ibis, 1870, 

 p. 345. 



Like M.personata, Gould, of India, but with the back black instead 

 of grey. 



Hainan ; Szechuen, extending to Nepal. 



194. Motacilla frontata, Swinh. P. Z. S. 1870, p. 129. 



Motacilla, sp. 1, Ibis, 1867, p. 390. 

 Amoy in winter. 



195. Motacilla baicalensis, n. sp. 

 Motacilla dttkhunensis (?), P. Z. S. 1870, p. 130. 



The representative in Eastern Asia of M. alba, L., of Europe ; 

 with clearer plumage, smaller bill, wing of a lighter brown, with 

 much more white, especially on the wing-coverts. In full summer 

 plumage the pectoral black contracts on the throat, and falls short of 

 the chin. It has a very close ally in M. dukhunensis, Sykes, of 

 India, but may be distinguished from that by its larger bill, greater 

 amount of white on the wing-coverts; and in nuptial dress by the 

 form of the pectoral patch. Occasional specimens from Trans-Baikal 

 have a black line uniting the back of the eye with the black of the 

 nape, but otherwise similar to the typical bird. This I would 

 propose to distinguish as var. temporalis. It will probably be the 

 bird procured in Lombardy in the collection of Count Turati of 

 Milan (see Baron de Selys-Longchamps in Ibis, 1870, p. 451). 

 Numerous skins of the Baikal Wagtail have been received through 

 Madame Verdey of Paris ; and it is doubtless the species observed bv 

 me on the Upper Yangtsze (P. Z. S. 1870, p. 130).
