Genus PORZANA

The little, short-billed, long-toed Water-Rails, with a brown back, grey or greyish breasts, and more or less white spotting, form a fairly natural genus. The bill is comparatively short and moderately stout. The tarsus, which is at least half as ong again as the bill, is considerably shorter than the middle toe and claw. The 2nd quill is longest, or 2nd and 3rd subequal; the 1st is much shorter, and about equal to the 6th or 7th. The tail-coverts extend nearly or quite to the end of the tail.

The Little Crake, Rallus parvus, has been separated from the Spotted Crake and its allies on account of having slightly shorter secondaries, and some difference in Coloration between the sexes, and was referred to Leach's genus Zapornia by Sharpe; but I cannot regard the Little Crake as generically distinct from its near ally, Baillon's Crake, which has the same relation between the secondaries and primaries as the Spotted Crake, the type of Porzana.

The genus Porzana is almost cosmopolitan. Three species are Indian, all of which are migratory, though one breeds in India.
