The Scincidæ, or Scinks, are an extensive family of smoothscaled lizards, frequenting dry and stony places, and almost universally distributed over the globe, being only absent from the cold northern and southern zones. The family itself is a very natural one, and it contains many natural genera; but a large number have been established which probably require careful revision. The following include the more important and the best established groups :

Scincus (2 sp.), North Africa and Arabia; Hinulia (20 sp.), most of the Australian and Oriental regions; Cyclodina (1 sp.), Hombronia (1 sp), and Lygosomella (1 sp.), all from New Zealand; Keneuxia (1 sp.), Philippines, Moluccas, and Papuan Islands; Elania (1 sp.) New Guinea; Carlia (2 sp.), North Australia and New Guinea; Mocoa (16 sp.), Australia and New Zealand, with species in Borneo, West Africa, and Central America; Lipinia (3 sp.), Philippine Islands and New Guinea; Lygosoma (12 sp.), Australia, New Caledonia, Pelew and Philippine Islands; Tetradactylus (1 sp.), Hemierges (2 sp.), Chelomeles (2 sp.), Omolepida (1 sp.), Lissolepis (1 sp.), Siaphos (1 sp.), Rhodona (3 sp.) Anomalpus (1 sp.), Soridia (2 sp.), and Ophioscincus (1 sp.) all confined to Australia; Cophoscincus (3 sp.), Philippine Islands, Celebes, and Queensland; Plestiodon (18 sp.), China and Japan, Africa, and America as far north as Pennsylvania and Nebraska; Eumeces (30 sp.), South Palaarctic, Oriental and Australian regions, to New Ireland and North Australia; Mabouya (20 sp.), Oriental region, AustroMalaya, North Australia, the Neotropical region, and to Lat. 42° 30' in North America; Amphixestus (1 sp.), Borneo; Hagria 1 sp.), and Chiamela (1 sp.), India; Senira (1 sp.), Philippine Islands; Brachymeles (2 sp.). Philippine Islands and Australia; Ophiodes (1 sp.), Brazil; Anguis (3 sp.), West Palearctic region and South Africa; Tribolonotus (1 sp.), New Guinea; Tropidophorus (2 sp.), Cochin-China and Philippine Islands; Norbea (2 sp.), Borneo and Australia; Trachydosaurus (1 sp.), Australia; Cyclodus (8 sp.), Australia, Aru Islands, and Ceram; Silubosaurus (2 sp.), Egerina (2 sp.), and Tropidolepisma (6 sp.), all peculiar to Australia; Heteropus (7 sp.), Australia, Austro-Malaya, and Bourbon; Pygomeles (1 sp.), Madagascar; Dasia (1 sp.), Malaya; Euprepes (70 sp.), Ethiopian and Oriental regions, AustroMalaya, South America (?); Celestus (9 sp.), peculiar to the Antilles, except a species in Costa Rica; Diploglossus (7 sp.), the Neotropical region;-with a number of other genera founded on single species from various parts of the world.
