CRAKE. La3 
23° 24' W., more than 500 miles from the coast of 
Treland, a Virginian Rail, Rallus virginianus, came 
on deck and was captured. Both this and the last- 
named species visit the Bermudas annually, although 
this group of islands is distant from Cape Hatteras, 
the nearest point of the North-American coast, about 
600 miles! 
The well-known Corn Crake, too, is a summer visi- 
tant to Greenland, has been met with on several oc- 
casions on the eastern coast of the United States, and 
has also been procured in Bermuda. 
Two instances are on record of the occurrence in 
Great Britain of the Purple Gallinule, Porphyrio 
hyacinthinus, in a quasi-wild state; but these had 
doubtless escaped from some ornamental water. 
Order V. NATATORES. 
Fam. ANATID &. 
POLISH SWAN. Cygnus immutabilis, Yarrell. 
Hab. Uncertain; but presumably the countries bordering 
the Baltic. 
In January 1838 flocks of this species were seen 
pursuing a southern course along the line of our 
north-eastern shores, from Scotland to the mouth of 
the Thames, and several specimens were shot (Yar- 
rell, Hist. Brit. Birds, vol. iii. p. 231).
