 pointed, prominent, as long as or a little longer than the ej'e ; 

 canthus rostralis obtuse ; loreal region oblique, concave ; nostril 

 equidistant from the eye and from the end of the snout ; distance 

 between the nostrils greater than the interorbital width , which is 

 less than that of the upper ej-elid ; tympanum very distinct, f to I the

 when the limbs are folded at right angles to the body ; tibia 3 to 

 3J times as long as broad, twice or a little more than twice in 

 length of head and body, shorter than the fore limb, which nearly 

 equals the length of the foot. Toes rather long and slender, 

 obtusely pointed, \ webbed, 3 phalanges of fourth and 2 of third 

 and fifth free ; outer metatarsals separated nearly to the base ; 

 subarticular tubercles rather feeble ; no tarsal fold ; inner metatar-
