Rallina Reichenbach, Synops. Avium, i (1845).
Type by orig. desig,, Rallus fasciatus Raffles.
The birds of this genus differ from Rallus in having a shorter bill, which is much shorter than the middle toe which, again, is shorter than the tarsus; the wing is rounded, the third primary longest. In Rallina canningi the secondaries slightly exceed the primaries in length and in the other species are a little shorter.
The genus ranges from India and Ceylon to Australia and three species are found within our limits.
