EUDYPTES DIADEMATUS. 47 



looking not unlike "whiskers" on a front view, have given rise to the 

 name "sea-cats", occasionally applied to these birds. 



On January 1)9, being then at sea, in latitude 39° 28' south, longitude 

 64° 33' east, and fully six hundred miles from the nearest land, a smaH 

 penguin, supposed then to be one of this species in poor plumage, was 

 observed following the ship. It seemed to mistake the ship (Mononga- 

 hela) for an island, and swam around it nearly all day, trying to find a 

 landing-place, the wind being light, and the ship going from two and a 

 half to three knots through the water. We had thus an excellent oppor- 

 tunity to observe from above the penguin's manner and great facility in 

 swimming. It always dives when intending to swim with speed, and 

 uses its flipi)ers with great effect, looking precisely like a fish — a small 

 shark, perhaps. It had not the slightest difficulty in keeping up with us.

A fragment of skin, from a characteristic spot (top of the head), enables me to iden- 

 tify the species as au inhabitant of Kerguelen's Land. — C. 



These penguins nest upon Kerguelen Island, as I am informed, but 

 not upon that part selected by our party as an observing-station ; nor 

 have I any other specimens than a scal^), brought me as a present from 

 Heard's Island by one of the elephant-sealers. It appears, however, 

 that they do not differ materially in habits from E. chrysolopha, choosing 

 the same localities for nesting, and progressing by the same hopping 

 gait.
