Allied Species and Representative Forms.—N. variegatus, 
with the lower back more streaked in the adult than in the 
young, is the true Eastern representative. It inhabits the 
greater part of Siberia where it breeds, migrating over the 
Asiatic Continent and as far south as Australia. 
N. hudsonicus, with the axillaries rich buff, is the 
American representative, but has been obtained in Iceland 
and once in Spain, whereas our own bird, as a wanderer, has 
been recorded from Greenland (Saunders). 
ESKIMO CURLEW. Nwmenius borealis (R. J. Forster). 
Coloured Figures.—Dresser, ‘ Birds of Europe,’ vol. viii, pl. 575 ; 
Lilford, ‘ Coloured Figures,’ vol. v, pl. 54. 
During the autumnal migration this small American 
species has, on a few occasions, deviated from its usual line 
of migration and touched upon our shores.
