APPENDIX. 
nostril towards hinder extremity ; supra-nasal plates narrow, oblique, and internally almost contiguous ; 
naso-rostral five-sided, anteriorly acute ; fronto-nasal plates four-sided, not in contact, being separated 
by the intervention of the anterior extremity of the frontal. Frontal plate pear-shaped, the broadest 
portion in front ; fronto-parietal plates four-sided, the inner and outer sides much the longest. Parietal 
plates three-sided, pointed behind ; interparietal plate rhomboidal, the two anterior sides very short. 
A narrow transverse plate behind each parietal plate. Freno-nasal plate narrow transversely; ffenal plate 
an oblong square ; preocular plate four-sided. Scales of upper lip exclusive of rostral, and of lower exclu- 
sive of mental, 9 ; respectively. Scales of back and tail six-sided, and faintly three-keeled. External 
ear-opening circular, and about a line and a half behind angle of mouth ; its edge smooth. The ground 
colour of the upper surface of the head, the back, and the upper and lateral parts of the tail, intermediate 
between reddish brown and hair-brown ; each scale on the back narrowly edged with liver-brown. 
Sides of the body liver-brown, variegated sparingly with small sienna-yellow spots ; below, the brown 
is gradually lost in the colour of the belly. The colour of the sides is separated from that of the back by 
a narrow yellow or reddish-yellow line, which proceeds on each side from the eyebrow, and is gradually 
lost on the base of the tail, a little posterior to the hinder legs. Under parts wine-yellow ; the inferior 
surface of the head and the throat freckled with short waved bluish-green lines. The belly strongly 
tinted with green. Length from nose to base of tail, 1 inch 8 lines ; length of tail, 2 inches 4 lines ; 
transverse diameter of body, about 3 lines. 
Inhabits the interior of Southern Africa, and specimens'are rarely procured.

Inhabits most parts of Southern Africa, and is found under stones, or in loose soil near the roots 
of shrubs. 
LITHOPHILUS, n. g. 
Ch. Gen. Figure serpentiform. Nostrils lateral, in the hinder edge of the rostral plate. 
Teeth conical, simple, and thinly set. Tongue flat and fleshy, the tip membranous, entire, and with a 
longitudinal gutter, the middle portion coated with thin scales, the hinder portion with transverse rugae. 
Palatal slit long, bifid anteriorly. Interparietal and parietal plates cover the whole of the hindhead. 
Palpebral plates in a row, edging the frontal and interparietal plates ; a row of small scales under the 
outer edge of palpebral plates. Eye small; eyelids distinct. No external ear-opening. No extremities. 
Scales smooth.* 
LITHOPHILUS INORNATUS, n. s. 
Head somewhat four-sided ; hindhead rather broad ; sides converge toward the nose, the latter 
is rounded. Body cylindrical, slender, and throughout nearly of equal thickness. Tail cylindrical, and 
tapered, point rather acute ; rostral plate semicircular ; nasal plates behind nostrils subovate, and 
contiguous; naso-rostral plate rhomboidal or imperfectly six-sided; fronto-nasal wanting, or forming on 
each side the anteriormost palpebral plate. Frontal plate large anteriorly, somewhat bell-shaped, 
posteriorly convex, the centre of the convexity projecting ; no fronto-parietal plates ; interparietal plate 
very large, somewhat cordiform, the concavity enveloping the hinder edge of frontal plate. Parietal 
plates narrow, lengthened, and posteriorly contiguous. Palpebral plates five in a row, and a small one 
* Were it not that the species of this group are without extremities, they might be ranged, as far as most characters are 
concerned, in Scelotes of Fitzinger.
