tinguished by the rufous-buff margins to the greater wiug- 
covertSj the much less extensive white patch on the throat, 
and the more dusky breast and under parts. At first sight the 
rufous-margined wing-coverts might be mistaken for immature 
plumage, but this is not the case. 
Specimen a, a breading male shot on the 11th of April, and 
specimen c, a male shot on the 1st of May, have the plumage 
o£ the upper parts, wings, and tail uniform dark brown and 
extremely worn. They are just commencing to moult ; a few 
dark brown rufous-margined wing-coverts and one or two 
of the secondary quills are partially grown. Specimen e, 
which was shot on the 6th of May, and specimens b and dj 
females, shot on the 1st of May, have already assumed a 
considerable amount of new plumage, the rufous-edged wing- 
coverts and innermost secondaries being already full-grown ; 
moreover, specimen b has already moulted most of its tail, 
the new feathers having the basal half white and the terminal 
half black narrowly tipped with white. 
Male. Wing 3*4 inches; tail 2-l-2'3; tarsus l'l-l-2. 
Female. Wing 3*25-3 inches; tail 2'05-2'2; tarsus 1-05.
