DESCRIPTIONS OF TWO NEW SOUTH AFRICAN LIZARDS, 
TETRADACTYLUS LAEVICAUDA AND T. FITZSIMONSI. 
By John Hewitt. 
T etradactylus laevicauda, sp. nov. 
Body elongate : limbs short but fully developed and pentadactyle . 
the length of the hind limb slightly exceeds the distance between the 
end of the snout and the base of the forelimbs. Doisal shields fairly 
strongly striated over the greater part of the body, but those on the 
neck are only very feebly striated and none are keeled, the posterior 
dorsal and anterior caudal shields being quite devoid of a median keel. 
The head shields are quite smooth with trace of ribbing. The caudal 
shields over the greater portion of the tail are quite smooth, but at its 
base they are carinate like the posterior dorsal shields, a condition 
which rapidly gives place to feeble ribbing a short distance behind 
the base of the tail : the -ventral and lateral caudal scales are quite 
smooth, except in the terminal third of the length of the tail, where 
they are keeled; in the terminal fourth all the caudal scales, including 
the dorsals, are strongly keeled. Dorsal shields in 13 longitudinal and 
62 transverse series : ventrals in 8 longitudinal series. Femoral 
pores 7 on each side. General colour olive, with a pale dorsolateral 
band commencing as a narrow streak near the nostril, passing along 
the supraciliary scales and the outer margin of the parietals to the 
neck, then continuing along the body and gradually broadening, being 
broadest about the middle of the body, where it is about two scales 
broad, then gradually narrowing and ending on the basal portion of 
the tail. Sides of head, neck, and body and upper surface^ ui the 
limbs brownish black : upper lip with pale spots : smaller pale spots 
also occur on the sides of the neck interiorly and on the anterior part 
of the flanks. Ventral surfaces, except the tail, pale : the scales 
immediately bordering the lateral fold spotted with black on the neck 
and bodv. Tail brownish olive 
Total length 185 mm. (tip of tail lost), length of head measured 
laterally 10.5, breadth of same 7.25, lengdh of forelimb 12.75, hind- 
limb 20.75, of tail (minus tip) 122. 
This description is based on a single specimen from Tabamhlope, 
Natal, number 2524 in the collection of the Transvaal Museum. 
This species is closely related to T. seps, Linn, from which it 
differs chieflv in the nature of the carination of the dorsal scales and 
also in the number of femoral pores. T . seps is at present known 
only from the western parts of Cape Colony, the most eastern records 
being Xnysna. 
Tetrad)cvctylus F itzsimonsi, sp. nov. 
Serpentiform : Forelimbs completely absent, hindlimbs minute, 
undivided, with a single terminal claw and with two or three femoral 
pores. Dorsal shields in 14 longitudinal and 69 or 70 transverse 
series : ventrals in 6 longitudinal series. Head shields smooth, inter- 
parietal elongated about twice as long as broad or even more. All
