 lowing bird, which, with the biil and plumage of some of the typical 

 IVadiug Birds, exhibited the tridactyle conforniation and general 

 character of the legs of some of the Charadriadcc. Iti the former 

 particulars it approaclied to Ihis and Numeniiis ; in the latter to Hee- 

 viatopus. A knowledge oniy, it vvas observed, of its habits and in- 

 ternal construction, at present vvanting, could determine with accu- 

 racy the exact affinities of the group, which was thus characterized :
