 some of the exterior edges of the wing feathers, which are white. The

 angered or pleased, raise or fall the feathers of its crest. 



ORDER XV.— PALMIPEDES. 



Birds of this order have the bill of various forms ; legs short, placed more 

 or less backwards ; the anterior toes partially or wholly connected by webs, 

 and in some families all the four toes united by one membrane ; the hinder 

 toe interiorly articulated to the tarsus, or, in some genera, wanting. 



THE SKIMMER, OR CUTWATER," 



Is twenty inches in length, and in breadth three feet seven inches. The 

 bill is of a very singular structure, the upper chap, or mandible, being above 

 an inch shorter than the under, and the upper shuts into it, as a razor into 

 its handle. The base of the bill is red, the rest black; and on the sides are 

 several furrows. The forehead, chin, and all the under parts, are white; 

 tne upper parts of the plumage black, with a bar of white across each wing. 



1 Rhyvchops nigra, Lin. The genus Rhynchops has the hill long, straight, flattened into 

 a blade, truncated at the apex; upper mandible much shorter than the under; nostrils 

 lateral, marginal, remote from the base ; legs slender; tarsus larger than the middle toe ; 

 the fore toes united by a membrane; hind toe joined on the tarsus; tail forked, and 

 shorter than the wmgs. tt^
