tinguished by the rufous-bufF margins to tlic greater wing- 

 coverts^ the much less extensive white patch on tlie throat, 

 and tlie more dusky breast and under parts. At first sight the 

 rufous-mai'gined wing-coverts might be mistaken for immature 

 plumage, but this is not the case. 



Specimen a, a bresding male shot on the 1 Itli of April, and 

 specimen c, a male shot on the 1st of May, have the phimage 

 of the upper parts, wings, and tail uniform dark brown and 

 extremely Avorn. They are just commencing to moult ; a few 

 dark brown rufous-margined wdng-co verts 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 d, 

 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; tail2-l-2-3; tarsus 1-1-1-2. 



Female. Wing 3-25-3 inches; tail 2-05-2-2; tarsus 1-05.
