REPORT ON THE BIRDS — STEGANOPODES AND IMPENNES. 127 



" The sealers told me that these birds when they come up from the sea vomit up these 

 stones at the mouths of their burrows, and when they go to sea again they take in the 

 very same stones as ' ballast.' The sealers say the fur-seals take in ballast in the same 

 way as the Penguins."

On comparison of the Kerguelen specimens of this Penguin with others from the 

 Falklands we find no reason for considering them otherwise than of the same species. 

 There is, however, less appearance of the white upper tail-coverts in the Falklands 

 specimens. Why Mr Sharpe should have referred Eudyptes chrysolophus (Sclater and 

 Abbott) of the Falklands to Eudyptes saltator we cannot understand, nor can we appre- 

 ciate the characters by which he separates his Eudyptes saltator from Eudyptes chrysocome. 



Forster evidently had both the " Rock-hopper " and " Macaroni " Penguins under his 

 eyes when he described his Aptenodytes chrysocome. 1 Brandt first clearly separated the 

 two species, which are quite distinct and easily recognised by the characters which 

 he has given. 



The type specimen of Eudyptes diadematus, Gould, for which we have made every 

 inquiry, is unfortunately no longer to be found. Mr Gould has parted with it, he knows 

 not whither. It was probably only an individual variety of this species. 



The plate represents an adult of this species (c), and the pale variety (e), both from 

 Kerguelen. 



I extract the subjoined account of the nesting of this Penguin at Kerguelen from 

 Mr Moseley's Notes (p. 195) :— 



" On the talus slopes beneath the cliffs, along the whole south side of Christmas Har- 

 bour, are vast Penguin rookeries, the Penguins here nesting amongst the stones where vege- 

 tation is entirely wanting ; and to the north of the harbour at its entrance are other 

 similar rookeries. Towards the upper part of the harbour, the rookeries are those of the 

 smaller crested Penguin, called ' Rock-hopper ' by the sealers, the same as that at Marion 

 Island ; but nesting scattered amongst these is another kind of Penguin, Eudyptes 

 chrysolophus, the Macaroni of sealers. 



' He describes the crest " in aliis individnis in fronte unita, in aliis divisa " (I. s. c, p. 137).
