C. pluvialis, but the smoky-brown axillaries distinguish the species 

 at all ages. 



It has been the usual custom amongst ornithologists to recognize 

 two races of the Smaller Golden Plover — an Eastern form, C. fulvus, 

 and a Western one, 0. dominions. The latter form, which inhabits 

 America, is, according to Mr. Seebohm, a slightly larger bird, with 

 a wing measuring 6 - 8 to 7'5 inches, whereas in the Asiatic species, 

 which visits Alaska also, the wing does not exceed 6 - 7 inches. The 

 distance between the tips of the long secondaries and the tip of the 

 wing is said by Mr. Seebohm to be shorter in Asiatic specimens than 

 in American ones. On examination this proves to be the case in 

 the majority of specimens, but it is by no means a constant cha- 

 racter, and, as Mr. Seebohm himself allows, intermediate forms 

 occur. In Mr. Bidgway's ' Manual ' it is stated that C. dominions 

 has longer wings, relatively shorter tarsi and toes, and less golden 

 coloration, especially in immature and winter plumages. The wing 

 is given as 6 - 8-7'4 inches, and the tarsus P55-1-82. In C. fulvus 

 the wing is stated to be 6-1-6-8 and the tarsus P6-1-8. It may, 

 therefore, be admitted that there is a slight difference in the size of 

 the two races, but they seem to overlap to such an extent that 

 I have thought it best to unite them. The supposed more golden 

 coloration of the Asiatic bird is not confirmed by our large series in 

 the Museum. 



Hob. The northern portions of both the Old and New "Worlds in 

 summer, winteriug far to the South in both hemispheres. Its place 

 in Europe, where it is only an occasional visitor, is taken by 

 C. pluvialis. Specimens from Eastern North America are some- 

 what larger (vide supra).
