dorsal plumage and on the breast than C. longipes has, the prevailing colour on the former bird being brown of 

 two shades in winter, interspersed with black and golden in summer. 



" I have a Golden Plover in my collection which was taken at sea in lat. 69° 30' N., long. 173° 20' E., 

 many miles N.W. of Point Barrow. This is the furthest point north, so far as I am aware, at which a Golden 

 Plover has been met with. 



"These measurements, as well as the general coloration, show that the specimen is referable to the Asiatic, and 

 not to the American race, although it was met with much nearer to the American than to the Asiatic coast." 



Unfortunately we have not all the plumages of the American Golden Plover represented in the series 

 before us, and we cannot therefore give a detailed account of the changes through which the bird passes. For 

 comparison, however, with the Eastern Golden Plover, we give a comparative list of the measurements of the 

 specimens examined by us, as follows : —

A summary of these measurements gives the following result : — 

 Ch. virginicus: Long. tot. 8-8-10-0 inches, culmen - 9-l - 0, al. 6 - 6-7'3, caud. 2 - 5-2 - 9, tars. l - 6-l - 7, dig. med. 



0-9-10. 

 Ch.fulvus: Long. tot. 7*5-9'0 inches, culm. 0-75-1-05, al. 5-9-6-65, caud. 2-2-2-5, tars. 1-55-1-6, dig. med. 



0-95-1 -05. 



It will be seen, therefore, that the American bird is almost always larger ; for, though some specimens of 

 Ch. fulvus are nearly equal in size to Ch. virginicus, there are none of them which get the wing 7 - 3 inches 

 in length. The tarsus of the American species seems to us to be shorter, and the colour of the upper 

 surface always more grey, especially about the hinder part of the neck. Whether the summer plumage presents 

 any differences will remain to be seen. 



Explanation of the Plates. 



The first Plate represents the adult male of the Eastern Golden Plover in full breeding-plumage, while on 

 the left is drawn a bird in autumn rapidly losing the black garb of summer. This bird is represented with its 

 wings raised, in order to show the smoke-coloured axillary plumes, by which it may be distinguished at once 

 from both the common Golden and the Grey Plovers. 



On the second Plate is seen the bird in winter plumage (figs. 2 & 3) ; and the mottled appearance on the 

 breast, which we take to be the last remains of summer plumage, and to which we have made frequent reference 

 above, is represented. In the foreground is a Grey Plover in full winter dress. We believe that there will 

 now be no difficulty in recognizing any of the species of Grey or Golden Plovers in Europe by the aid of the
