338 Lacertidas. 



mouth between the 5th and 6th upper labials. 2 or 3 small upper 

 temporal shields sometimes present; temporal scales granular, smooth, 

 .lower much lar^^er ; a tympanic shield usually present ; no auricular 

 denticulation. Lower eyelid opaque, with feebly enlarged scales in 

 the middle. 6, rarely 4, pairs of chin-shields, exceptionally 4 on one 

 s.ide and 6 on the other, the three anterior in contact in the middle; 

 17 to 29 gular scales in a straight line between the symphysis of the 

 chin-shields and the median collar-plate ; gular fold distinct. Collar 

 feebly curved, free, composed of 7 to 12 rather large plates. 



Scales granular and smooth, larger, flat and often squarish on the 

 sides towards tlie veutrals, 46 to 62 across the middle of the body, 

 usually 49 to 61. Ventral plates not forming regular longitudinal 

 series, tessellated, mostly as long as broad, some broader than long, 

 in 28 to 33 more or less angular transverse series, the longest of which 

 contain 12 or 14 plates, usually 14. Preanal region covered with 

 numerous small, irregular plates. 



Upper surface of arm with rather large, smooth, hexagonal or 

 i-hombic scales. Scales on upper surface of tibia similar to dorsals 

 or a little smaller ; lower- surface with one row of very large and one 

 of small plates. 8 to 12 femoral pores on each side, the two series 

 widely separated from each other in the middle. Subdigital lamellae 

 19 to 24 under the fourth toe, unicarinate, a second keel being formed 

 by the outer lateral series of scales. 



Upper caudal scales more or less oblique and diagonally keeled, 

 the scales small in the middle on the basal part, the scales on tlie 

 lower surface of Avhich are smooth ; 26 to 46 scales in the fourth 

 or fifth whorl behind the postanal granules. 



The young are grey or olive above, with 3 or 4 wliite, black-edged 

 streaks on each side of the neck, the ujipermost from the superciliary 

 edge, the second from the lower eyelid, passing above the tympanum, 

 the third from the upper lip, through the tympanum, the fourth, 

 if present, from the lower lip to the forearm ; in addition, two dorsal 

 series of round white, black-edged ocelli. On the body the upper 

 or dorsolateral streak as well as the third may be broken up into 

 ocellar spots, whilst the second is always represented by a series 

 of ocelli similar to the dorsals. These markings may persist in the 

 adult, or the streaks may disappear and be replaced by 6 or 8, 

 rarely 10, series of spots, which may be incompletely surrounded by 

 dark brown rings, or transversely connected by large dark brown 



received by the Genoa Museum, both agreeing in this respect. I have also 

 examined in the Paris Museum an ocellalcd young from Mongolia (David 

 Collection) in which the subooular borders the mouth.
