33^ PATAGONIAN EXPEDITIONS: ZOOLOGY 



until the outermost rectrix is almost white with five distinct dttsky bars. 

 The outermost feathers are narrow or lanceolate as compared with the 

 same feathers in G. delicata which in a general way this species closely 

 resembles. 



Wings : Upper coverts blackish brown, the marginal ones uniform, the 

 median and greater series spotted by the whitish tips of each feather. 

 Bastard wing and primaries blackish with five white tips. 



Quills : Outer web, of first primary white or greyish white. Other- 

 wise the quills are dusky or blackish, the secondaries being conspicuously 

 tipped with white, and the first secondaries do not exceed the longest pri- 

 mary coverts in length. The innermost secondaries are barred black and 

 rusty cream buff like the longer scapulars in general effect. 



Lower parts : Chin deep creamy buff, and unmarked. The whole 

 under neck similar in tone but streaked and mottled and almost barred in 

 appearance by the irregular dark brown or blackish areas on each feather. 

 From the lower breast back the ground color is white plain medianly and 

 heavily barred with blackish on the sides and flanks. Under tail coverts 

 washed with pale creamy buff and barred with blackish, somewhat irregu- 

 larly. Under wing coverts, whitish barred with dusky, the primary series 

 greyish with white tips. Axillaries, regularly barred black and white, the 

 white bars a little the wider. 



Bill : Olive brown, darker at the tip, and shading to green yellow at 

 the base. 



Feet and legs, olive brown. 



Iris, dark hazel.

The sexes do not vary in appearance, but winter birds are suffused and 

 the markings are not so clearly defined. 



Young birds of the year are more rusty in general tone, especially on 

 the throat, breast and back. 



There is a wide individual difference in the Patagonian Snipe but the 

 material is not sufficient to generalize upon, though a correlation of two
