seems to consist of a distinct piece articulated with the remainder. 
Their nostrils are united and form a tube laid on the back of the 
upper mandible; there is a nail planted in the heel, but no thumb. 
Of all'the Palmipedes, these remain most constantly at a distance 
from land, and when a tempest supervenes, they are forced to seek 
shelter on reefs and ships, from which circumstance they derive 
their name of Storm Birds: that of Petrel—Little Peter—has been 
given to them on account of their habit of walking on the water, 
‘which they effect by the aid of their wings. They make their nests 
“in holes of rocks, and eject on those who. attack them an oily fluid 
with which their stomach seems to be always filled. The greater 
number inhabit the Antarctic Seas. 
’ Those species are more particularly called Perrets—Procet- 
~ LARIA—whose lower mandible is truncated.
