 This stage soon gives place to a darker coat of down, to the 

 tips of which the paler down of the first coat is attached for a 

 time. In this second coat of down, the upper parts, including 

 the head, are slate-grey, the plumes of the back having pale 

 tips, and the under surface is white. When only a few days 

 old, the bill begins to assume the orange tint characteristic 

 of the adult birds. 



The adults obtained in February are in faded plumage, 

 and late in that month and during March and April had 

 either moulted their tails or had that appendage only in an 

 incipient stage of growth. 



Eighty specimens, of mixed sexes, weighed on April 28th, 

 1903, varied from 8'5 to 13*75 lbs. Of these, the heaviest 

 male scaled 13 - 75 lbs., the heaviest female 125 lbs.

The presence of this species at the South Orkneys is 

 an interesting discovery, since it indicates a considerable 

 extension in its hitherto-known range, for there was no 

 reliable evidence before that the Macaroni Penguin had 

 occurred south of the Falklands and South Georgia in the 

 western Antarctic seas, or of Heard I. in their eastern waters. 



Whether this species is an annual visitor, having breeding- 

 grounds in the South Orkneys^ must remain an open 

 question ; but it would seem not unlikely that such is the 

 case, perhaps on some of the unexplored islands of the 

 Archipelago. 



Five specimens were obtained in 1904 in the Penguin - 

 rookeries on Laurie I. These were mostly captured singly 

 towards the end of summer, and are regarded as being 

 more or less immature birds. Two of them, namely those 

 last obtained, are decidedly younger than the rest, and 

 have the merest indications of yellow feathers on the 

 sides of the crown, and also small bills. The remaining 

 three are considered to be not fully adult, and have well- 

 developed tufts of golden-yellow (not orange) plumes, but
