The Lacertidse, or Land Lizards, are small-sized, terrestrial, 
non-burrowing lizards, very characteristic of the Palsearctic 
region, which contains more than half the known species, and of 
the adjacent parts of the Oriental and Ethiopian regions, but 
extending also to South Africa, to Java, and even to Australia. 
The best-defined genera are the following : — 
Lacerta (10 sp.), ranging over all Central and South Europe 
to Poland, and farther north in Russia and Siberia, eastward to 
Persia, and southward to North and West Africa; Zootoca (8 
sp.), has nearly the same range in Europe as the last genus, 
but has representatives in Madeira, South Africa, and Aus- 
tralia ; Tachydromus (7 sp.) is widely scattered in Chinese 
Asia, Japan, Borneo, and West Africa ; Acanthodactylus (10 sp.) 
is most abundant in North Africa, but has a species in South 
Africa, and two in Central India; Eremias (18 sp.) is found all 
over Africa, and also in the Crimea, Persia, Tartary and China ; 
Psammodromus (2 sp.), is confined to Spain, France, and Italy ; 
Ophiops (6 sp.), inhabits India, Persia, and Asia Minor to South 
Russia. Less strongly marked and perhaps less natural genera 
are the following ; — 
Thetia (1 sp.), Algiers; Teira (1 sp.), Madeira; Nucms (4 
sp.), Caucasus and South Africa ; Notopholis (4 sp.), South 
Europe and South Africa ; Algira (3 sp.), North and South Africa ; 
Scrapteira (1 sp.), Nubia ; Aspidorhinus (1 sp.), Caspian district ; 
Messalina (4 sp.), North Africa, Persia, and North-west India 
Cab'ita(l sp.), Central India; Pachyrhynchus (1 sp.), Benguela.

The Zonuridse, or Land Lizards, characterised by a longitudinal
