26 Lacertidx. 



narrow, obtusely pointed, a little louger than the postocular part of 

 the head, with sharp canthus and nearly vertical, concave loreal region. 

 Pileus 2? to 2 1 times as long as broad. Neck as broad as or broader 

 than the head. Hind limb reaching the shoulder, the collar, between 

 the collar and the ear, or, rarely, the ear ; foot \\ to If times as long 

 as the head ; toes slender, feebly compressed. Tail rather flattened at 

 the l)ase, 2 to a little over 3 times the length of head and body. 



Nostril pierced between 3 or 4 shields, the nasal sometimes forming 

 a narrow rim separating it from the upper labial ; nasals forming a 

 suture behind the rostral, the suture } to ^ the length of the fronto- 

 nasal, which is broader than long and broader than the internarial space ; 

 prefrontals forming a median suture ; frontal as long as its distance 

 from the rostral or from the end of the snout, 1} to 2 times 

 as long as broad, rounded in front, narrow behind, grooved in its 

 anterior half or f ; parietals l.V to 1^. times as long as broad, lateral 

 border sometimes slightly emargiuate in front for the accommodation 

 of the anterior temporal ; interparietal l^ to 2i- times as long as broad, 

 often separated from the occipital by one or two small shields, rarely* 

 by the parietals meeting in the middle; occipital small, \ to \ the 

 length of the interparietal, sometimes a little broader. Of the 4 supra- 

 oculars the tirst, which is always in contact with the frontal, and the 

 fourth are nearly constantly divided into 2 to 7 small plates or granules ; 

 second and third large, second often a little longer than third ; 6 or 7,. 

 rarely 5, 8 or 9 superciliaries, separated from the supraoculars by a 

 complete series of granules. Rostral not entering the nostril ; 2 super- 

 posed postnasals ; anterior loreal \ to I the length of the second ; 

 usually 6 upper laliials, sometimes 5 or 7, rarely 4 or 8, upper labials 

 anterior to the subocular, which is much narrower beneath than al)Ove. 

 Lower eyelid opaque, t with a series of vertically enlarged scales in the 

 middle. A long and narrow, more or less distinctly keeled upper 

 tempoi'al, I'arely divided into two, followed l)y one, two or more small 

 shields, in contact with the fourth supraocular ; temporal scales very 

 small and granular above, larger beneath ; a distinct tympanic shield ; 

 exceptionally 3 to 5 projecting scales form a denticulation in front of 

 the ear-opening. 



4 or 5 pairs of chin-shields, the first three in contact in the middle ; 

 28 to 47 gular scales in a straight line lietweeu the symphysis of the 

 chin-shields and the median collar-plate ; no gular fold. Collar with 

 strongly serrated edge, composed of 7 to 14 plates, usually lU to 12.

t Bedriaga says of liis L. dorirp, var. martensi, " Das iintere Aiigenlid ist 

 meistens durchsichtig," but I am unable to confirm this statement from the 

 specimens at my disposal.
