But for the longer tail, proportions much as in L. agilis. Head a 

 little broader than deep, If to 1| times as long as broad, its length 

 (to posterior border of ear-opening) 4 to 41 times in length to vent ; 

 snout obtuse; cheeks swollen in the male. Pileus twice as long as 

 broad. Body scarcely depressed. Hind limb reaching the wrist or 

 the axil ; foot as long as the head or a little longer ; digits feebly 

 compressed. Tail nearly twice as long as head and body. 



Nasals in contact behind the rostral ; frontonasal broader than 

 long ; praefroritals forming a median sutui'e, or frontal narrowly in 

 contact with the frontonasal ; frontal about If times as long as 

 broad, as long as its distance from the end of the snout; fronto- 

 parietals much shorter than the frontal ; parietals 1| times as long 

 as broad ; interparietal 2 to 2| times long as broad ; occipital very 

 small. Four supraoculars, first and fourth small, first in contact 

 with the frontal ; 4 or 5 superciliaries, in contact with the supra- 

 oculars. 



Two superposed postnasals ; anterior loreal not half as long as 

 second ; subocular not or but little narrower beneath than above, 

 between the fourth and fifth upper labials ; two large upper temporals, 

 first much longer than the second and in contact with the fourth 

 supraocular; lower temporal scales rather large, upper smaller and 

 granular ; a large tympanic shield. Five large and vertically elongate 

 scales in the middle of the lower eyelid.
