[blocks in formation]

The Scincide, 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.), Omolepido. (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 Palæarctic, 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 Palæarctic 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.

Family 46.—OPHIOMORIDÆ. (2 Genera, 2 Species.)

[blocks in formation]

The snake-like Lizard constituting the genus Ophiomorus, is found in Southern Russia, Greece, and Algeria; while Zygnopsis having four weak limbs, has been recently discovered by Mr. Blanford in South Persia. The family is therefore confined to our Mediterranean sub-region,

FAMILY 47.—SEPIDÆ (7 Genera, 22 species.)

[blocks in formation]

The Sepidæ, or Sand-Lizards, are a very natural group, almost confined to the Ethiopian region, but extending into the desert country on the borders of the Oriental region, and into the south of the Palearctic region as far as Palestine, Madeira, Spain, Italy, and even the South of France. The genera are :

Seps (10 sp.), South Europe; Madeira, Teneriffe, Palestine, North Africa, South Africa and Madagascar ; Sphenops (2 sp.), North Africa, Syria, West Africa ; Scelotes (3 sp.), Angola to South Africa, Madagascar ; Thyrus (1 sp.), Bourbon and Mauritius; Amphiglossus (1 sp.), Madagascar ; Sphenocephalus (1 sp.), Afghanistan ; and Sepsina (4 sp.), South-west Africa.
