A Greenland specimen from Sukkertoppen, also an adult female, 

 varies from the above described bird, in having more buff on the 

 under parts, and considerable white on the abdomen; the flank 

 feathers are also more buff, as the bars are decidedly buff. 

 The date of capture of this example is not given and it is impos- 

 sible to tell whether it has quite assumed the breeding plumage, 

 or is passing from it, but as there are no feathers of an autumn 

 dress visible it is probable that the breeding dress is not yet 

 completed; the autumn dress seems to be ochraceous, mottled 

 with black, and black blotches interspersed on the upper parts.
