26 Lacertidm. 



A series of 6 or 7 transversely enlarged plates on the lower surface 

 of the forelimb. Scales on upper surface of tibia smaller than dorsals. 

 11 to 16 femoral pores on each side. 25 to 31 lamellar scales under 

 the fourth toe. 



Caudal scales forming whorls of nearly equal length, upper rather 

 narrow, the median pair often broader, rather strongly keeled, truncate 

 or Tery obtusely pointed behind, usually with more or less distinct 

 sensory pits. 



As in the preceding species, the markings differ very strikingly 

 according to individuals and some at least of the different patterns, on 

 which species have been founded, perhaps indicate local forms or 

 varieties. I here enumerate those with which I am acquainted, 

 beginning with the most primitive. 



A. (£. tseniolata, Smith.) Eight white streaks on the back and sides, 

 sometimes nine on the nape and anterior part of back, separated by 

 black streaks ; the outer dorsal light streak extending to the fourth 

 supraocular, the upper lateral, originating just above the ear, some- 

 times broken up into spots. Posterior part of back and tail brown 

 above, the latter inclined to red near the extremity and with a blackish 

 lateral streak. Lower parts white. — " Grassy districts of Cape Colony," 

 Smith; Little Namaqualand ; Pine Town, Natal (S. African Museum). 

 (Ann. S. Afr. Mus., pi. vii, fig. 6.) 



B. (L. livida, Smith.) Back with light and dark streaks as in the 

 preceding, or pale buff behind with black vermiculations ; sides black 

 with numerous small white spots, which form irregular vertical bars 

 on the temple and neck. — " Northern parts of Cape Colony," Smith ; 

 Little Namaqu aland ; Deelfontein. (L.c, figs. 7, 8.) 



c. (L. tessellata, Smith ; T. ornata, G-ray.) Neck and anterior part 

 of back black, with 3 or 4 white lines above and very regular 

 white vertical bars on the sides posterior part of body grey or 

 pale buff, with more or less ; distinct black bars on the sides. Tail 

 coral-red or reddish, at least in the young. — " Eastern parts of Cape 

 Colony," Smith ; Clanwilliam, Calvinia, Worcester, Klipfontein, in 

 Cape Colony ; Little Namaqualand ; Zambesi (Sir J. Kirk). (L.c, 

 figs. 9, 10.) In the var. pseudotessellata, described by Bedriaga from 

 Mozambique, there are five white lines on the nape. 



D. {L. elegans. Smith.) Pale reddish brown above and on the 

 sides ; two white, black-edged streaks on the neck. — " Little Namaqua- 

 land and the country towards the Orange Eiver," Smith ; Smithfield, 

 Orange Eiver Colony. 



In the following tabulation of specimens examined, the same 

 arrangement is adopted.
