Sr. Cii Head \vith an elongated, compressed, semicircular crest. Anterior extremity of nostrils reaching not quite as 

 far as the middle of commissure. Frontal feathers extending nearly as far as half the distance from lateral feathers to 

 nostril; the latter much beyond the feathers on side of lower mandible. Bill shorter than head.

 without transverse bars; the white of wings less extended. 



Length, 17.50; wing, 7.90; tarsus, 1.20; commissure, 1.98. 



Hob. Whole of North America. 



The beautiful hooded merganser is extremely common in winter on the fresh water lakes 

 near Fort Steilacoom, where I obtained several fine specimens of both sexes. They also breed 

 sparingly in the neighborhood. 



In the summer of 1856 I shot one out of a brood of half-grown young, which were being 

 reared on a small sluggish stream near the garrison garden. Being but slightly wounded, it 

 showed great dexterity in swimming, diving, and hiding, and other spirited endeavors to escape. 

 The rest of the brood, being unharmed, took to the shore and managed most successfully to 

 hide in the long grass near the water. The individual shot was about two-thirds grown, and 

 seemed to be in color an exact miniature of the adult female. S. 



The hooded merganser is often shot in winter, but I never saw it during summer in the 

 Territory. C.
