With the common tern, formerly known as SternaJiintndo a name properly belonging apparently inpart to an Arctic species), we come to the typicalrepresentative of the genus Sterna, and therefore of the entire sub-family. In common with the allied species (exclusive of the gull-billed Common Tern(Sterna fluviatilis).. MOUNTED IN THE RO STUDIOS COMMON TERN (SUMMER) tern, whose slight differences from the ordinar\ type have been alreadynoted), this tern has the outer tail-feathers elongated and pointed, thetail deeply forked, with its outer feathers also elongated and generallymore than half the length of the wing, the shank of the leg short andinferior in length to the middle toe and claw, and the beak generallyslender (although heavy in the Indian river-tern, Sterna seena).Something like forty species are included in the genus, which has acosmopolitan distribution. Unlike the marsh-terns, these birds arechiefly maritime in their haunts, and are in consequence collectivelydesignated sea-terns. The present species, in the adult condition, is specially characterisedby the orange-red beak, coral-red legs, and the pale lavender-grey tintof the lower surface of the body ; the crown of the head and nape in 1/2 GILL GROUP summer being of the normal black, while the upper-parts in generalare dark pearl
