Avere from the southern lacertokles^ which must now be placed in 

 the genus Amelva, instead of from the ocelUfer of Spix, which was 

 not mentioned. Since the specimens designated as Jujgomi apparently 

 differ in no way from oceJUfer, Boulenger (1885, p. 372) is followed 

 in reducing the species to the synonymy of this form. 



Diagnosis. — This distinct species may be readily recognized by the 

 following characters: parietals 5; supraoculai's normally 4; supra- 

 ocular granules usually extending forward past the anterior border 

 of the third supraocular ; femoral pores 7-12 ; ventral caudals keeled 

 or ridged as in leinniscatus; anal spurs not developed; size always 

 small. 



Description. — Snout moderately pointed; nostril usually in suture 

 between anterior and posterior nasal plates; anterior nasal not in 

 contact with second upper labial; supraoculars normally 4; supra- 

 ocular granules usually extending forward to or past the middle of 

 the second supraocular, rarely just reaching the posterior border; 

 frontoparietals normally 2 ; parietals 5 ; anterior and posterior gulars 

 often poorly differentiated, but graded and smaller posteriorly; 

 anterior gulars usually with a pair of enlarged baskets of scutes 

 laterally, and at times a smaller one medially ; mesoptychials modera- 

 tely large, largest medio-laterally or at a point just to the side of the 

 median line, smaller toward sides, in 1-4 rows, posterior usually 

 largest; postmesoptychial granules minute, rarely extending to the 

 edge of the posterior gular fold, except at the median line. 



Body elongate ; ventral plates in eight longitudinal rows, external 

 ones sometimes reduced, and in 26-33 transverse rows; dorsal 

 granules small; limbs Avell developed; brachials 3-5; antebrachials 

 2-3; brachials usually continuous with antebrachials at a point of 

 contact; postantebrachials granular or slightly enlarged; femorals 

 -^6; tibials 2-3; femoral pores 7-12; tail elongate, tapering, with 

 moderate, oblique scales; caudals keels moderate, more or less 

 irregularly arranged on sides, but forming continuous longitudinal 

 ridges below. 



The coloration is moderately variable. Lower surfaces white, 

 yellowish, or light blue; lower flanks bright blue, deeper colored 

 than the median ventral plates; tail white or yellowish below, 

 apparently even in the young; tail brownish or olivaceous above, 

 often more or less spotted with dark brown; two more or less 

 distinct lateral stripes may be continued from each side of the body 

 to the tail ; femora usually more or less spotted and reticulated with 

 Avhite above, line behind; ground color above brownish, blue-gray, 

 gray, blue-black or reddish, often varied in each of the three major 

 fields, loAver darkest, middorsal lightest; pattern distinct in young, 

 but sometimes much faded in adults; sides with two distinct light
