62 Lacertidee. 



ou tlie posterior border, iu 8 (rarely 6) longitudinal and 27 to 33* 

 transverse series (27 to 30 in males, 31 to 33 in females) ; the plates of 

 the 6 principal rows subequal in size or those of the second series from 

 the median line the broadest ; if in 8 rows, outer plates usually narrow, 

 exceptionally half as broad as those of the adjacent series. 



Preanal plate modei'ate or rather small, sometimes divided into 

 three, bordered by two semicircles of small plates. 



Scales on upper surface of tibia much smaller than dorsals, strongly 

 keeled. 19 to 23 lamellar scales under the foui-th toe. 14 to 20 femoral 

 pores on each side. 



Caudal scales obtusely pointed, the upper more or less oblique, 

 diagonally and strongly keeled, the lower also keeled, except quite at 

 the base ; the Avhorls usually not very unequal in length ; 24 to 30 

 scales in the fourth or fifth whorl behind the })0stanal granules. 



Grey or pale brown above, with two darker dorsal bands, each beai'ing 

 a series of dark brownf spots, which may be large and squarish or 

 small and irregular, or replaced by a series of small ocelli on both 

 sides of the dark dorsal band ; bordering these spots on each side a 

 small white spot or streak, the outer of which is the continuation of a 

 streak proceeding from the outer border of the parietal ; nape usually 

 with a short dark brown vertebral streak or series of spots ; a more 

 or less distinct whitish streak ou each side from the upper lip to the 

 thigh ; between it and the dorso-lateral series of light spots a dark 

 band with a series of large squarish or round dark brown spots mostly 

 Avith a white centre, or of white, black-edged ocelli, which iu males 

 may be very large and blue ; upper surface of head without spots, or 

 with small dark markings following the curved inner border of the 

 supraocular region; tail with a more or less distinct, dark lateral 

 band and with or witliout a dorsal dark band or series of large dark 

 spots. Lower parts white in the female, pale yellow in the male ; in 

 the latter some small blue spots may be present on the sides of the 

 belly; According to Werner, the young differs only in having the 

 light streaks more distinct, more continuous. 



The pattern of coloration is derivable from that of the young of L. 

 agilis, var. exigua, as figured by me (1916), p. 13. The remains of a dark 

 vertebral baud, which persist on the nape only, result from the fusion 

 of the dark borders of the light vertebral streak after the absorption 

 of the latter, as in the typical form of L. agilis ; the paired dorsal spots 

 represent the breaking up of the inner dark border of the dorso-lateral 

 light streak, Avhich retains its normal course instead of being shifted 



* Up to 35 accordin<^ to Werner. 



t Sometimes reddish bi'own in females, fide Werner.
