mouUi i)etAveeii the 5th au'l (3tli upper labials. 2 or 3 small upper 

 temporal shields sometimes preseut; temporal scales granular, smooth, 

 lower much larger ; a tympanic shield usually present ; no auricular 

 deuticulatiou. Lower eyelid opaque, with feebly enlarged scales iu 

 the middle. 5, rarely 4, pairs of chin-shields, exceptionally 4 on one 

 side and 5 on the other, the three anterior in contact in the middle; 

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

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

 feebly curveil, free, composed of 7 to 12 ratlier large plates. 



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

 sides towards tlie ventrals, 4() to 62 across the middle of the body, 

 usually 49 to 61. Ventral plates not forming reguLir 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. Prcaual region covered with 

 numerous small, irregular plates. 



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

 rhombic 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 femoi-al pores on each side, the two series 

 widely separated from each other in the middle. Subdigital lamell<e 

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

 by the outer lateral series of scales. 



Upper caudal scales more or less obliijue and diagonally keeled, 

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

 lower surface of which are smooth ; 26 to 46 scales iu the fourth 

 or iifth whorl behind the j^ostanal granules. 



The young are grey or olive' above, with IJ or 4 white, l>lack-edgcd 

 streaks on each side of the neck, the uppermost 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 li[) 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 liy 6 or 8, 

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

 dark brown rings, or transversely connected by large dark brown 



i-eceived by the Genoa Museiuii, botli agreeing in this respect. I have also 

 examined in the Paris Musevmi an ocellated yoniiy from Mongolia (David 

 Collection) in which tlie suljocular borders the moutli.
