THE PENGUIN, (Speniscus demersus,) 
Of which numerous species abound on the shores and 
islands of the great Southern Ocean, is remarkable for 
its almost incredible agility in the water ; it swims and 
dives like a^fish, and in fact is described as coming to 
the surface for air, and descending again so suddenly 
as to give rise to the impression that it is a fish jumping 
in sport. It is found in vast numbers in hiding places, 
where the females are seen sitting upright and holding 
their single egg between their legs.
