300 LacedidK. 



upper surface of the snout, exteudiug to tlie niiJdle of the frontal 

 shield. Pileus nearly twice as long as broad. Neck a little narrower 

 than tlie head. Hind limb reaching the collar or a little beyond ; 

 foot l:|r times as long as the head; toes rather slender, feebly com- 

 pressed. Tail twice or a little less than twice as long as head and 

 body. 



Upper head-shields flat, very rugose with granular asperities. 

 Nasals in contact with each other behind the rostral, the suture 

 between them ;} to a the length of the frontonasal, which is a little 

 broader than long ; prefrontals as long as broad or longer than 

 broad, separated by au azygos shield ; frontal a little shorter than its 

 distance from the end of the snout, H to If times as long as broad, 

 separated from the supraoculars by a series of small scales ; parietals 

 as long as broad ; interparietal larger than the frontoparietals, in 

 contact with or narrowly separated from a very small occipital. Two 

 supraoculars, together hardly -f the length of the supraocular region, 

 the first shorter than the second, the space in front of which is tilled 

 by 4 or 5 transverse series of granules ; 6 or 7 superciliaries, separated 

 from the supraoculars by 2 or 3 series of granules. Three nasals, 

 lower in cont:ict with the rostral and the first upper labial ; anterior 

 loreal as long as deep or a little deeper than long, shorter than the 

 second ; 4 or 5 upper labials anterior to the subocular, which is keeled 

 below the eye and largely borders the mouth, its lower boriler much 

 shorter than the upper. Temporal scales granular, keeled ; no 

 tympanic shield; no auricular denticulation. Lower eyelid with a 

 transparent disc formed of two large Ijlack-edged scales. 



Four pairs of chin-shields, the first 3 in contact in the middle. 31 

 or 32 gular scales in a straight line between the symphysis of the 

 chin-shields and the median collar-plate ; no gular fold. Collar 

 straight, free, composed of 11 plates. 



Scales granular and keeled on the nape, rhombic, feebly imbricate, 

 and strongly keeled on the body, graduating into the eaudals, larger 

 and smooth towards the ventrals ; 51 to 56 scales across the middle 

 of the body. Ventral plates in 12 or 14 rather irregular longitudinal 

 and 33 to 87 rather angular transverse series, the plates as long as 

 broad or a little broader than long. Preaual region covered with small 

 irregular pbites. 



Scales on upper surface of fore limb moderately large, keeled. 

 Scales on upper surface of tibia rhombic, feebly imbricate, keeled, 

 as large as the posterior dorsals ; one series of very large and one 

 of small plates on the lower surface; 13 or 14 femoral pores on each 

 side. Subdigital lamella; bicarinate, spinulose, 21 under the fourth toe.
