Most of the specimens examined (including all those from Alaska) are in juvenile 

 plumage, birds in summer plumage beicg relatively rare in collections. There is a 

 remarkable difference in size between two adult males from Australia and New Zea- 

 land, respectively, and I suspect there may be two forms, the respective breeding 

 ranges of which remain to be determined. Their measurements are as follows: 



c All Alaskan specimens examined are young birds of the year. 



<* Latham's Brown-eared Sandpiper was based on a '"Watling" or "Lambert" 

 drawing (no. 244) now iu the British Museum, which Sliarpe (Hist. Coll. Brit. Mus., 

 Birds, 1906, 147) identified as Tringa acuminata Horsfield. Mathews (Xovit. Zool., 

 XATii, 1911, 7) has since examined this dra^\'ing and finds it a "good figure of Linn^'s 

 hypoleucos" (i. e., Actitis hypoleucos).
