each scale; and the different species inhabit both the Old World 
and the New, as well as Australia. The Galliwasps (Céestus) of the 
West Indies, and sundry other genera, do not greatly differ. Of 
Tropidophorus, which has exceedingly rugged scales, the species 
inhabit the Indo-Chinese countries, and one (Z: cocinsinensis) is 
found likewise in the Philippines ; while of another (Z: Berdmore’), 
in Burmah, Mr. Theobald remarks that “its scales are dull and 
lustreless, and the coloration peculiar for a Scink. It harbours under 
half-immersed stones, and enters the water freely.” In several of 
this family of Lizards the scales are beautifully iridescent, and many 
of them show longitudinal pale or white lines, or are otherwise 
variegated. | 
Nearly akin to the extensive family of Scéucide, there are three 
small families (as classed by Dr. Gray), the species of which are 
peculiar to Australia. They have small, undivided posterior limbs 
only, or are quite limbless. These families are the Zza//scda, founded 
on three or more species of a single genus, Zia/s; the Afrasiade, 
founded upon one species only~-Agrasia pulchella, which is limbless ; 
and the Pygopodide, comprising the two genera Pygopus and Delma, 
the former containing two, the latter only one ascertained species. 
The Gymnopthalmide constitute still another small family, quadru- 
pedal, but with the limbs small and weak. Of seven genera referred 
to it, five are Australian, one is European, and one belongs to South 
America. Adlepharus pannonicus is a small Lizard of this family, 
inhabiting Eastern Europe, with a congener, A. d¢vittatus, in the 
Caucasus; and Gymnopthalmus lineatus found in Brazil and the Island 
of Martinique. 
In the second tribe of Ledtog/ossa, entitled Cyclosaura, the scales 
of the be!ly are square, in cross bands; those of the back and tail 
are rhombic and imbricate, or circular and subgranular ; the tongue 
is lengthened, and more or less conspicuously furcate ; and the eyes 
are diurnal, having two valvular lids. The limbs are generally well 
developed; but in several genera they still are more or less rudi- 
mentary, or even absent. 
There are four small families in which the sides are rounded and 
covered with scales like the back. Of these, that of Chamesauride 
is founded upon the South African Lacerta anguina of Linnzeus, now 
Chamesaura anguina, which has the limbs quite rudimentary. In 
the American families of Cercosauride, Chirocolide, and Anadiade, 
the limbs are moderately developed, and have each five toes. The 
two last-mentioned families are founded each upon a single species, 
Chirocolus imbricatus and Anadia ocellata; and the other contains
