acuminate and projecting ; canthus rostralis angular ; loreal region 

 concave ; nostril much nearer to the end of the snout than to the 

 eye ; interorbital space as broad as the upper eyelid ; tympanum very 

 distinct, nearly as large as the eye. Fingers rather slender, hrst not 

 extending beyond second ; toes nearly entirely webbed; tips of fingers 

 and toes dilated into small but well-developed disks ; subarticular 

 tubercles moderate ; a small o\'al inner metatarsal tubercle ; no

" Snout of moderate length, ver}' little longer than the distance 

 between the eyes, moderately pointed. Canthus rostralis triangular 

 or nearly so. Loreal region between the nostril and eye flat, 

 perpendicidar and then abruptly rounded outwards to lower jaw. 

 Nostril slightly below the canthus rostralis and nearer to the end of 

 the snout than to the eye. Upper jaw not projecting much below 

 the lower. Tympanum distinct, small, about one thirtl the size of 

 the eye. The vomerine ridges begin on a line with the anterior 

 internal angle of the choanae, in two oblique lines, increasing in 

 size from the front, converging behind, but separated by a con- 

 siderable interspace. A glandular fold along the side of the back, 

 with a very indistinct one from the tympanum to the shoulder. 

 A few enlarged glands behind the mouth, with a short fold meeting 

 the one from the tympanum and ceasing behind the shoulder. From 

 the vent to the heel is slightly in excess of the length of the body. 

 The length of the foot is about half the length of the body. Disks 

 large. The thumb is a little shorter than the second finger, which 

 is about one fourth shorter than the fourth. The third finger 

 is one third longer than the fourth. Toes broadly webbed, the 

 membrane reaching to the disks of all except the fourth. Dark 

 slate-colour above, obscurely marked witli large darker spots. 

 A deep bluish-black band from the nostril through the eye and 

 tympanum, and along the sides on which it expands, and is obscurely 

 spotted with darker. A pale bluish line from the eye along the 

 glandular fold. Upper surface of legs greyish, obscurely banded 

 and mottled with slaty brownish. Back of thighs finely reticulated 

 with brown. Under surface yellowish. Upper lip, postoral glands 

 and fold yellowish, faintly mottled with dark slaty. A narrow
