nioutli between the 5tli airl Gtli upper labials. 2 or 3 small upper 

 temporal shields sometimes present; temporal scales granular, smooth, 

 lower nuieh lare-er ; a tympauie shield usually present ; no auricular 

 denticuiation. Lower eyelid opaijvu', witli i'eel)ly enlarged scales in 

 the middle. 5, rarely 4, pairs of ehin-sliields, exceptionally 4 on one 

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

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

 chin-shields an<l 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 s(|uarish on the 

 sides towards the ventrals, 4() (o t')2 ;u'i<jss 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 Avhich 

 contain 12 or 14 plates, usually 14. Preaual 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 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, tiuicarinate, a second keel being formed 

 by the outer lateral series of scales. 



Upper caudal scales more or less ol)lique and diagonally keeled, 

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

 lower surface vi which are smooth ; 26 to 46 scales in the fourth 

 or fifth whoii Ijehind the postanal granules. 



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

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

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

 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 bi'oken 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 Museuui, both agreeing' in this resisect. I have also 

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

 Collection) in which the suljucular borders the mouth.
