The Cyprinidae, or carp, are largely represented in southern Asia, and there grow to a size unknown in Europe; a Barbus in the Tigris has been taken of the weight of 300 Th.
They are in fact allied to the carps or Cyprinidae and the cat-fishes or Siluridae.
Cyprinidae.-Mantle open in front, with two pallial sutures; external gill-plates smaller than the internal.
CARP, the typical fish of a large family (Cyprinidae) of Ostariophysi, as they have been called by M.
One member of the Cyprinidae is at present known to be viviparous, but no observations have as yet been made on its habits.
The Cyprinidae' are divided into four subfamilies: - Catostosninae (mostly from North America, with a few species from China and eastern Siberia), in which the maxillary bones take a share in the border of the mouth, and the pharyngeal teeth are very numerous and form a single, comb-like series; Cyprininae, the great bulk of the family, more or less conforming to the type of the carp; Cobitinae, or loaches (Europe, Asia, Abyssinia), which are dealt with in a separate article (see LoAcH); and the Homalopterinae (China and south-eastern Asia), mountain forms allied to the loaches, with a quite rudimentary air-bladder.
The fish known as loaches (Cobitinae) form a very distinct subfamily of the Cyprinidae, and are even regarded by some authors as constituting a family.
Among Indian fishes, the Cyprinidae or carp family and the Siluridae or cat-fishes are best represented.
The Siluridae, or scaleless fishes, and the Cyprinidae, or carp and loach, form the bulk of the mountain fish, :and the genera and species appear to be organized for a mountaintorrent life, being almost all furnished with suckers to enable them to maintain their positions in the rapid streams which they inhabit.
