ting one-third of the whole length. The snout is rounded ; its upper 

 surface is smooth, and slightly sloping towards the snout. The 

 phrenic region, laterally, is more depressed than in Lejjtodactylus ocella- 

 tus, thus causing the canthus rostralis to be more apparent. The 

 nostrils are small, oblong, and nearer the margin of the upper jaw 

 than the anterior rim of the eye. The eyes, themselves, are of 

 medium size, subcircular ; their diameter being equal to the distance 

 between them and the nostrils. The upper lid is smooth ; its exterior 

 margin thin, but much less projecting over the eye than in Leptodac- 

 tyhis ocellatm. The interocular space is about equal to the width of 

 the upper lid, but smaller than the diameter of the tympanum, and a 

 little wider than the radius of the orbit. The tympanum itself is 

 circular, very conspicuous; its diameter being about two-thirds that 

 of the eye. The mouth is large, and the tongue, thickish, subelliptical, 

 but slightly free posteriorly, and likewise slightly emarginated upon 

 its extremities. The symphysis of the lower jaw is provided with 

 a tubercle or knob fitting the anterior eraargination of the tongue 

 as also a depression in the upper jaw. The inner nostrils are sub- 

 circular, and of medium size. The vomerine teeth, situated behind 

 the latter, constitute two regular arches, more distant from each other 

 than in Lepiodactylus oceUcdus. The openings of the Eustachian tubes 

 are very conspicuous, and longitudinally subelliptical. 



The body is raniform, elongated, subcylindrical. The anterior legs 

 are proportionally shorter than in Lepiodactylus ocellatus, although 

 the fingers project a little beyond the groins when bent backwards 

 alongside the body. The first finger is much longer than the second, 

 which is equal to the fourth. The fingers, themselves, are subcylin- 

 drical, tapering, and provided with small tubercles under the articula- 

 tions of their phalanges. The palm of the hand is smooth; the ex- 

 ternal metacarpal disk is much less conspicuous than the internal 

 one, which is quite developed and oblong-shaped. The hind legs have 

 the same proportional development as in Lepiodactylus ocellatus; they 

 are longer than the body and head together, of the whole length of 

 the feet. The thighs are much stouter than in Leptodactylm ocellatus. 

 The tarsus is provided with a similar membranous fold along its 

 inner edge. There is an outer, large, metatarsal, very much de- 

 pressed disk, and a rather small tubercle at the base of the inner toe. 

 The sole of the feet is smooth. The toes are subcylindrical, slender, 

 tapering, and provided under their articulations with small tubercles.
