Ohs. The bill of the Oystercatcher varies greatly in length, depending on the degree in which the tip is worn off : 
many examples shot on rocky coasts have the extremities quite truncated, measuring perhaps T ’ ¥ inch in width, 
the appearance of the outer surfaces of the mandibles showing that this is the result of friction ; the Chinese 
form, H. osculans, which I doubtfully include with ours, appears to have normally a considerably larger bill, as 
will be seen by the above measurements ; Mr. Hume gives the extreme length in Indian specimens as 3 - 6 inches. 
Asiatic specimens appear to average larger in the tarsus than European. 
Iris variable, orange-red, red, brownish red ; eyelid orange-red ; bill orange-red at the base, the terminal half of the 
upper mandible changing to blackish, and the tip of the lower mandible to brownish ; legs and feet dusky purplish 
(in spring purplish pink) ; feet duskier than the tarsus. 
Head, entire neck, and upper back uniform coal-black, with a small white patch beneath the eyelid ; scapulars, tertials, 
wing-coverts, primaries, and the terminal portion of the secondaries and terminal portion of the tail brownish 
black, not so intense as that of the head and throat ; greater wing-coverts, except at the base, the inner secon- 
daries entirely, and the rest, with the exception of the above-mentioned portion, white ; the greater part of the 
inner webs of the primaries, from the base outwards, white, running onto the centre of the outer webs of all but 
the first two primaries, and ending on the third in an elongated shaft-patch ; first two primary-shafts white near 
the tip, the remainder white where the webs are this colour ; entire under surface, with the under tail-coverts 
and under wing, as also the back, rump, upper tail-coverts, and basal two thirds of the tail, white.
