deepening into chestnut in the region of the vent; the under tail- 

 coverts with blackish shaft-lines ; some of the lesser wing-coverts 

 near the edge of the wing mottled with ashy-brown bases ; quills 

 ashy brown below. Total length 6"8 inches, culmen 0-35, wing 

 4-55, tail 3-45, tarsus 0-45. 



Adult female. Similar to the male in colour. Total length 

 6-7 inches, culmen 0-35, wing 4-5, tail 3"25, tarsus 0*4. 



Young birds are much duller in colour than the adults, being 

 dusky brown above with a blue gloss ; on the rump remains of 

 narrow rufous margins ; quills with narrow whitish edges at the 

 tips; frontal band very small and pale rufous; throat also pale 

 rufous ; the rest of the under surface very light rufescent butf, 

 deeper on the under tail-coverts ; on the lower throat some remains 

 of blackish mottlings, but not forming a cross baud. 



The young bird described is from Guatemala, and shows that, as 

 in H. rustica, the plumage of the young bird gets completely bleached 

 before it puts on the full spring dress in which it returns to its 

 summer home. The remains of blackish markings on the lower 

 throat indicate an approach to a complete band. 



There would appear to be some considerable difference in the 

 depth of the rufous colouring of the under surface, some specimens 

 being so richly coloured that they can scarcely be distinguished from 

 H. tytleri. The specimen recorded below from Toughoo is a typical 

 H. crythrof/astra, and agrees with North-American examples. 



Hah. The whole of North America, reaching to Alaska and 

 Greenland, extending across to Lake Baikal and wintering in 

 Burmah ; also ranging through the whole of Central America and 

 the Antilles, reaching in winter as far as Southern Brazil.
