principal supraoculars, not in contact with the first supraocular, although sometimes 

 very narrowly separated from it. Parietals 1| (young) to If times as long as broad, 

 usually not in contact with the upper postocular *, the outer border more or less 

 distinctly notched for the accommodation of the large temporal. Occipital as long 

 as or shorter thanf, and as broad as or broader than the interparietal. The two major 

 supraoculars, equal in length or the lirst longer, separated from the superciliaries 

 by a complete series of granules ; the fourth supraocular usually in contact with the 

 upper temporal. 6 or 7 superciliaries, second longest, the suture between them all 

 vertical or nearly so. 



Two superposed postnasals; two loreals, first usually shorter than second. A 

 rather large semitransparent area in the lower eyelid, with 7 to 9 vertically elongate 

 shields. 5 upper labials anterior to the subocular;];, the lower border of which is much 

 shorter than the upper. Temporal region with small granular scales ; masseteric 

 shield small or absent § ; tympanic present; a large anterior upper temporal, followed 

 by granular scales. 



No pterygoid teeth ||. 



22 to 27 scales and granules in a straight line between the symphysis of the chin- 

 shields and the median collar-plate ; gular fold absent or merely indicated. Collar 

 not serrated, composed of 9 to 12 moderate or small plates. 



Body covered with small smooth granules (sometimes faintly keeled on the 

 posterior part of the back), which are a little smaller on the sides than on the back ; 

 55 to 62 scales across the middle of the body, 3 or 4 transverse series corresponding 

 to a ventral plate, 31 to 44 in the middle of the back corresponding to the length of 

 the head. Ventral plates as often in 8 as in 6 longitudinal series, the fourth series 

 on each side composed of smaller but quite well-developed plates ; in 26 to 29 

 transverse series. 



Prseanal plate small or very small, in one (male) specimen divided into two, bordered 

 by two or more series of small plates or scales ; granules between the praeanal plate 

 and the anal cleft ^. 



Scales on upper surface of tibia obtusely keeled, smaller than dorsals. 27 to 31 

 lamellar scales under the fourth toe. 20 to 25 femoral pores on each side**. 



Caudal scales truncate, the upper more or less oblique, diagonally and strongly 

 but rather obtusely keeled, the lower smooth ; apical pits usually very distinct ; the 



* In contact in 3 cases out of 16. • f In one specimen barely half as long. 



J Karely 4 or (3, according to Werner. § Present in 5 cases only out of 16. 



II Minute teeth or their traces may be present, according to Mehely. 



i[ Absent, however, in one of the specimens (femal ). The importance of tliis cliaractcr has been 

 exaggerated by Mehely. 1 have shown that it is also found in L. ijracu, as well as in some specimens 

 of L. muralis. 



** Earely 16 to 19 and 26, Jide Bedriaga, Werner, and Mehely.
