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

 4 to 41 times in females ; snout pointed, with strong cauthus and 

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

 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 V\ times as long as broad, usually narrower behind 

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

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

 the interjDarietal, rarely nearly as large, often separated from it l)y 

 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

 the superciliaries. Nasal forming a suture with the anterior loreal

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

 with the second loreal, below the anterior.
