236 CALIDEIS. SANDERLING. 



quills twenty-five ; primaries tapering, the first longest ; 

 secondaries short, incurved, but the inner elongated, one of 

 them not much shorter than the first primary when the 

 wing is closed. Tail short, of twelve narrowed feathers, and 

 somewhat doubly emarginate. 



The only species of this genus known to me has the 

 habits of the Dunlin, to which also it is nearly allied in 

 structure and form. How any one, misled, perhaps, by the 

 absence of a hind toe, should place it in connection with the 

 Plovers, it would be difficult to say. They who give it a 

 station between the Turnstone and the Oyster-catcher, from 

 both of which it widely differs, may possibly consider such 

 remarks " uncalled for." Very interesting, too, it would be 

 to know the physiological facts and logical arguments, by 

 which the Ardeida? are made to occupy a station intermediate 

 between Plovers and Snipes.
