This specimen was found by the writer in the gray, upper 
Cretaceous shale, on the North Fork of the Smoky Hill River, 
in Western Kansas, 
Paleotringa vagans, sp. nov. 
greater portion of the shaft and distal end of a left tibia, some- 
what injured, but with its more characteristic portions still 
preserved. It indicates a bird somewhat smaller than Palco- 
tringa littoralis, described by the writer from the same me 723 
but is probably a closely allied form. From the tibia of that 
species, the present specimen may readily be distinguished by 
the proportionally more narrow and shallow tendinal canal, on 
the anterior face of the distal’ end, and by the more depressed 
supra-tendinal bridge. The trochlear surface, also, on the pos- 
terior side contracts more rapidly, and at its superior margin 
passes directly, and not abruptly, into the shaft.

This unique specimen was discovered at Hornerstown, New 
Jersey, about ten feet below the surface of the marl, and was 
presented to the Yale Museum by John G. Meirs, Esq. 
Yale College, New Haven, April 10th, 1872.
