A very striking modification of form was conspicuous in the fol- 

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

 Wading Birds, exhibited the tridactyle conformation and general 

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

 particulars it approached to Ibis and Numenius ; in the latter to Hce- 

 matopus. A knowledge only, it was observed, of its habits and in- 

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

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

 ralist, who had formed the collection in the Himalayan Mountains, 

 out of which the four preceding species were selected.
