width. Neck as broad as licad, or sli<;htly constricted. Limbs rather short ; hind 

 limb reacliing the wrist, the elbow, or the axil in males, limbs just meeting or hind 

 limb reaching the wrist or tlie elbow in females; foot longer than the head; digits 

 feebly compressed. Tail cylindrical, 1 ^ to 14 times as long as head and body. 



Nostril pieixed between the nasal and two postnasals, usually also the first upper 

 labial. Nasals forming a short or very short suture ; frontonasal broader than long, 

 broader than the internarial space, in contact witli the upper postnasal and the 

 anterior loreal ; frontal as long as its distance from the end of the snout. If to 

 2 times as long as broad, usually narrower beliiud than the major supraoculars ; 

 jiarietals 1^ to li times as long as broad, outer border convex, not in contact with the 

 upper postocular ; occipital h to | the length of tlie interparietal, as broad as or 

 broader than the latter, rarely a little narrower; second supraocular longer than third ; 

 ;") or G, rarely 4, superciliaries, first or second longest, the suture between these two 

 usually oblique, rarely vertical ; a series of granules between the major supraoculars 

 and the superciliaries, the series complete or incomplete, through the first or first and 

 second superciliaries forming a suture with tlie supraocular, or, rarely, reduced t<j 

 1^ or 3 granules. 



Kostral not touching the nostril ; first upper labial not always entering the nostril, 

 and if so only at a small point; two superposed postnasals; two loreals, first as long 

 as or shorter than second. 4 upper labials anterior to the subocular *, the lower 

 border of which is much shorter than the upper, sometimes f very short owing to a 

 part of the shield having become detached as on accessory fifth anterior upper labial. 

 Temporal region with moderately large shields or small scales ; masseteric shield 

 present, small or large, sometimes divided into two J ; tympanic present, large ; 

 a rather large upper temporal, forming a suture with the fourtii supraocular, followed 

 by 2 to 4 scales. 



Lower eyelid in the middle with one or two series of G to 8 enlarged scales, which 

 have a tendency to become semitransparent. 



Pterygoid teeth strongly developed. 



17 to 20 scales and granules in a straight line between the symphysis of the cliin- 

 shields and the median collar-plate; gular fold distinct. Collar strongly serrated, 

 composed of 7 to 1(J plates ^. 



Body covered with moderately large, juxtaposed or subimbricate, hexagonal or 

 rhombic scales, which are strongly and diagonally keeled on the back, larger and 

 losing the keels towards the ventrals; oo to 43 scales across the middle of the body, 

 2 transverse series (rarely 3 here and there) corresponding to a ventral plate, I'J to 30 



* 3 on one side in a female from Angora. 



t In one mule from Jiertheiti Miiniiuin, this reduction of the lower part of the subocular being the 

 nearest approach, in the genus Lacerla, to a condition frciiuent in Aaiiitltudactylnn and Ei-fmins. 

 X llurcly indistinct, according to Wcriicr. 

 ^ 7 to 12, according to Werner.
