For a limicoline bird, this tibio-tarsus is very short, stout, and with 

 bulky distal extremity. It is proportionately shorter and heavier 

 than is the tibio-tarsus in Scolopax, Philohela or Gallinago, while it 

 has almost identically the same limicoline characters. It has nearly 

 the same length as the tibio-tarsus of Aphriza virgata, but its condylar 

 end is again comparatively much stouter.^ 



As a matter of fact, I have compared this fossil tibio-tarsus with the 

 bone in many plovers, woodcock, snipe, stilts, avocets, godwits, willets, 

 curlews, sandpipers, lapwings, and their various allies, and I am of the 

 opinion that the form here noted is now extinct and its genus no longer 

 in existence. The specimen should be compared with the tibio-tarsus 

 from a skeleton of Pluvianellus sociabilis of South America, but I have 

 no such material at hand. 



As I say above, the distal part of the bone and lower shaft agrees 

 very closely with the same bone in Belonopterus chilensis, but in the 

 latter the tibio-tarsus has a length of 8.9 cms. (No. 18546. Coll. 

 U. S. Nat. Mus.) This Chilean species is a big plover. 



For this apparently extinct bird I propose the name of Limicolavis 

 pluvianella. -

Cormorants of several species, now extinct, were residents of the 

 Pacitic Coast of North America, and probably were found far inland, 

 extending from OHgocene time up to the present day. The species
