Scolopax leucurus. (Swainson.) White-tailed Snipe. 



Genus, Scolopax. 



Ch. Sp. Scolopax leucurus, rectricibus sedecem: lateralibus albis basi eoctus bis terve nigro fasciatis ; abdomine 



transverse fasciato. 

 Sp. Ch. White-tailed Snipe, tail of sixteen feathers : the three lateral ones pure white, with 2 — 3 basal black 



bands on the outer web ; belly transversely banded. 



A single specimen of this bird, in fine and perfect plumage, exists in the 

 British Museum. It is readily distinguished from all those which we have here 

 described, by the great proportion of white in the tail feathers, and by having 

 the middle of the body distinctly crossed by dusky black lines. — Sw. 



DESCRIPTION 



Of a specimen, from Hudson's Bay, in the British Museum. 



Colour. — Plumage of Sc. Drummondii and Wilsonii, except that the belly is barred with 

 blackish-grey, two or three bars on each feather. Tail : three or four outer pairs of feathers 

 white, with one or two irregular blackish bars near the bases of the outer webs ; three central 

 pairs black, with a broad ferruginous bar near the end, separated from the narrow white tip 

 by a black line. Bill and legs brownish (in the dried specimen). 



Form. — Bill much like that of Sc. Drummondii, but scarcely so much dilated at the point, 

 and stouter at the base. Second quill equal with the first. Tail, of sixteen feathers, consi- 

 derably rounded ; the three outer pairs of feathers diminishing successively in breadth, but 

 not much ; the outer ones having about three-fourths of the breadth of the middle ones. 

 Tarsus longer than in the two species just mentioned.
