narrow, obtu.sel_v pointed, a little loug'er than the jjostocular part of 

 the head, with sharp canthus and nearly vertical, concave loreal region. 

 Pileus 2| to 2 1 times as long- as broad. Neck as broad as or broader 

 than the head. Hind limb reaching the shoulder, the collar, between 

 the collar and the ear, or, rarely, the ear ; foot I5 to If times as long 

 as the head : toes slender, feebly compressed. Tail rather flattened at 

 the base. 2 to a little over 3 times the length of head and body. 



Nostril p)ierced between 3 or 4 shields, the nasal sometimes forming 

 a narrow rim separating it from the upper labial ; nasals forming a 

 suture behind the rostral, the suture .} to 4r the length of the fronto- 

 nasal, which is broader than long and broader than the iuternarial space ; 

 prefrontals forming a median suture ; frontal as long as its distance 

 from the rostral or from the end of the snout, 1^ to 2 times 

 as long as broad, rounded in front, narrow behind, grooved in its 

 anterior half or | ; parietals 1^ to If times as long as broad, lateral 

 border sometimes slightly emarginate in front for the accommodation 

 of the anterior temporal ; interparietal li to 2 J- times as long as broad, 

 often separated from the occipital by one or two small shields, rarely* 

 by the parietals meeting in the middle ; occipital small, i to ^ the 

 length of the interparietal, sometimes a little broader. Of the 4 supra- 

 oculars the first, which is always in contact with the frontal, and the 

 fourth are nearly constantly divided into 2 to 7 small plates or granules ; 

 second and third large, second often a little longer than third ; 6 or 7, 

 rarely 5, 8 or 9 superciliaries, separated from the supraoculars by a 

 complete series of granules. Eostral not entering the nostril ; 2 super- 

 posed postnasals ; anterior loreal J to J the length of the second ; 

 usually 6 upper labials, sometimes 5 or 7, rarely 4 or 8, upper labials 

 anterior to the subocular, which is much narrower beneath than above. 

 Lower eyelid opaque,t with a series of vertically enlarged scales in the

 temporal, I'arely divided into two, followed by one, two or more small 

 shields, in contact with the fourth supraocular ; temporal scales very 

 small and granular above, larger beneath ; a distinct tympanic shield ; 

 exceptionally 3 to 5 projecting scales form a denticulatiou in front of 

 the ear-opening. 



4 or 5 pairs of chin-shields, the first three in contact in the middle ; 

 28 to 47 gular scales in a straight line between the symphysis of the 

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

t Bedi'iaga says of his L. dnyire, var. martensi, " Das imtere Augenlid ist
