PATAGONIAN EXPEDITIONS'. ZOOLOGY. 



white or buffy white strongest, and finally the vent and lower abdomen, 

 as well as the under tail-coverts and the feathered portion of the legs, 

 clear, immaculate silvery white, silky in appearance. 



Bill : Yellowish, shading into dusky at the base. 



Iris: Orange-yellow.

Feet: The toes bare and with short hairy covering above, the tarsus
