The superior length of tail of the grey wagtail, its ash-co- 
loured back, and the want of the produced hind claw, will 
always prove sufficient tokens of distinction. 
Pirate 49. Fig. 3. A male bird, of the natural size. 
Crown of the head, nape of the neck, and ear-coverts, pale General 
wax-yellow. Back, rump, and scapulars, a darker shade geeHD> 
of the same colour. Over the eyes is a streak of gam- 
boge-yellow. Wing-coverts blackish-brown, margined and 
tipped with yellowish-white. Quills blackish-brown, mar- 
gined and tipped as above. Middle tail-feathers mar- 
gined with wax-yellow; the two outer ones, with the 
whole of their exterior and part of their inner webs white. 
Legs and toes blackish-brown. Hind claw produced, 
and but slightly curved. The female has the upper 
parts of the body darker, and more inclining to oil-green ;
