STORMY PETREL. Crass I. 
but a little attention to the text of each of those 
antient naturalists, is sufficient to evince that 
they are very different birds; the latter very ac- 
curately describes the characters of that species 
of swallow; while Piny expresses the very 
manner of life of our Petrel. 
“ Nidificant in scopulis, he sunt que toto 
mart cernuntur: nec unquam tam longo naves, 
tamque continuo cursu recedunt a terra, ut non 
circumvolitent eas Apodes.” £75. x. c. 39. 
In August 1772, I found them on the rocks 
called Macdonald’s Table, off the north end of 
the Isle of Skie; so conjecture they breed there. 
They lurked under the loose stones, but betray- 
ed themselves by their twittering noise.
