pulars, and lesser wing-coverts black. Wings and tail hair-brown, 
with a surface-wash of pale grey, chiefly conspicuous on the basal 
half of the latter; the feathers of the wing edged with pale 
buff, the greater coverts and tertials being strongly tipped with 
the same. A white spot, comprising the basal portions of the 
outer webs of the 2nd, 3rd, 4th, and 5th tertiaries, ornaments 
the wing. The singularly distinctive character whence I have 
taken its name consists in a white line, which, starting from 
the centre of the chin, runs down in front quite to the breast, 
broadening as it descends to the form of an isosceles triangle, 
a line of black spots edging for some distance the rufous that 
flanks its sides. Bill blackish brown, with bright yellow rictus 
inside the mouth. Legs and claws brown, strongly washed with 
ochre. Iris deep brown. 
Total length 7 inches; wing 4; tail 2^o, 
43. Pied Wagtail. 
Under this head we may note my species, Motacilla ocularis , a 
specimen of which, in full summer plumage, with grey back, is 
comprised in Mr. Whiteley's series. This bird resembles M . 
lugubris , though more delicately formed; but is always distin¬ 
guishable by the carpal region being grey instead of black, and 
in its summer plumage by its grey back. There is, moreover, 
less white on the wing. Mr. Blyth identified my bird with M. 
dukhunensis, Sykes ; but as I have taken the trouble to examine 
this species in the East Indian Museum, I can confidently assert 
that M. dukhunensis is one of the M. alba group, and not one 
of the White-winged group so conspicuous for the black line 
through their eyes. 
45. Yellow Quaketail. 
The specimens of this bird brought by Mr. Fleming agree 
with Budytes cinereocapilla of Europe, the wing-coverts only 
being a little more distinctly tipped with yellow. 
46. Wood Wagtail. 
This is the true Nemoricola indica, Gmelin, as Mr. Whiteley's 
specimens testify. 
51. Japanese Lark. 
Our two specimens of the Peking Lark do not agree with the
