As I have already remarked in my " Contribiitious, &c., No. 1" (Pr. 

 U. S. Nat. Mus., 1883, p. 09), the specimens of the Dunlin collected 

 by me on Bering Island are distinguishable from the typical Pelidna 

 alpina by its purer colors. Upon a close examination I now find that 

 my birds agree in every particular with the American form, not only 

 in size, but also in coloration, the bright rusty of the upper parts j) re- 

 dominating more and the black of the lower parts being more restricted 

 and of a deeper shade. From all data accessible to me I regard it as 

 certain that all references to a larger form of Pelidna alpina or cinclus as 

 occurring in the coast regions of Eastern and Northeastern Asia * belong 

 to this form, also including Swinhoe's cJiinensis., with which Taczanow- 

 ski's variety of the same name is not identical, being referable to a 

 smaller race, afterwards by him given as Tringa scliinzii. I have been 

 able to compare large series, and am inclined to think that Pelidna paci- 

 fica is entitled to full specific rank. 



In explanation of the change of name in this form a few remarks may 

 not be out of place : 



In 1822 C. L. Brehm described as Tringa scliinzii a small race of 

 Pelidna alpina L., from Central Europe. Bonaparte, on the other 

 hand, in 1820, in his "Observations on the Nomenclature of Wilson's 



* Birds from Amoy, China, Lave already been referred to americana by Mr. Harting 

 (/. 0.), and Dr. Bean has determined specimens from Plover Bay, Tscbutski Peninsula, 

 to belong to the same form.
