Body not or Init slightly depressed. Head feebly convex or even 

 quite flat above, 1^ to If times as long as broad, its depth equal to 

 the distance between the anterior corner or the centre of the eye and 

 the tympanum, its length 3| to 4i- times in length to vent in males, 

 4 to 4J- times in females ; snout pointed, with strong canthus and 

 nearly vertical loreal region, as long as the postocular part of the 

 head. Pileus 2 to 2^- times as long as broad. Neck narrower than 

 the head. The hind limb reaches the wrist, the elbow, or the axil in 

 females, the axil or the shoulder in males ; foot 1 to Ij times as long- 

 as head. Tail 2^ to 3|^ times as long as head and body. 



Nostril pierced between three (rarely four) shields. Eostral not 

 entering the nostril, often narrowly in contact with the frontonasal,* 

 which is as long as broad or slightly broader, as broad as or a little 

 broader than iuternarial space ; prefrontals forming a median suture ; 

 frontal as long as its distance from the end of the snout or a little 

 shorter, 1| to If times as long as liroad, usually narrower behind 

 than in front; parietals 1^ to 1^ times as long as broad; interparietal 

 1^- to 2 times as long as broad ; occipital small, much shorter than 

 the interparietal, rarely nearly as large, often sepai'ated from it by 

 one or two small shields or by the parietals meeting in the middle. 

 Four supraoculars, first very small, rarely broken up into 2 or 



3 granules, or in contact with the frontal,t or absent,:|: second and 

 third equal or second the longer, fourth small but larger than the 

 first and rarely broken up into 2 or 3 ; 4 or 5 superciliaries, first or 

 first and second longest and usually in contact with the supraoculars ; 

 a series of granules, rarely complete, between the supraoculai's and 

 the superciliaries. Nasal forming a suture with the anterior loreal 

 above the postnasal,§ often forming a very short suture with its fellow 

 behind the rostral ; anterior loreal shorter than second, sometimes 

 divided into two || and forming a triangle with the postnasal T[ ; usually 



4 upper labials, sometimes 3 t)r 5,** anterior to the subocular, which

^ As in L. agilis. — In a male from Kiu Kiang the postnasal forms a suture 

 with the second loreal, below the anterior.
