The relationships of this bird, the type specimen of which still remains nniiiue, are umiuestion- 

 ably with Actoilromas fiiscicollis, from which it could hardly be distinf,'uished, were it not for its 

 much greater size. The plumage is entirely the same, e.vcept that there is le.ss of n reddish tinge 

 above, and the upper tail-coverts nre more distinctly relieved by V-.shapcd markings of dusky. It 

 is totally distinct from 7'. canutus, with which it scarci-ly needs comparison at all, the very dilferent 

 proportions, aside from the differences in coloration, distinguishing it at once. 



The history of the niiinners, liabits, and distribution of this rare species continiios 

 to remain unknown, and its existence as a veritable species to rest on the eviih^ice of 

 a single specimen. The type, which has thus far remained uniipie, was taken on 

 the 24th of May, 1833, on liaynor South, Long Island, by William Cooper, and named 

 by I'rofessor Baird in honor of its discoverer. We know nothing as to any indi- 

 vidual peculiarities exhibited at the time of its capture, but we may venture the 

 suggestion that its habits probably do not essentially differ from those of the Bouor 

 parte Sandpiper.
