the name of Porphyrio (purple-coloured) on account of its colour. 
If it could be acclimatised, it would be a valuable addition to our 
ornamental waters. 
There are several varieties of this species, differing more or less 
from one another. ‘They inhabit the warmer regions of the Old 
World, such as Asia Minor, Africa, and the South of Europe; it is 
about the size of the ordinary domestic fowl. 
Rails (Aa//us) are characterised by a slender, tapering, slightly- 
arched beak, longer than the head ; elongated tarsi, terminating in

slender toes, much compressed and completely separate, and not 
marginate ; wings middle-sized ; tail short. 
Their habits bear a strong resemblance to those of the Gallinules. 
Like the latter, they are timid, and hide themselves in rushes, under- 
wood, or grass of the marshes and meadows they inhabit. ‘They 
make use of the burrows hollowed out by water-rats in which to take 
refuge when hard pressed. Little thickets bordering brooks, and 
small low-lying damp meadows, are localities to which they are 
peculiarly partial. Their flight is heavy and slow, not elevated, but 
is generally in a direct line. In running, however, they are adepts, 
and the means they adopt for escaping their pursuers often succeed.
