(Plate III, fig. 2, Text fig. 4.) 



Hyla eivingii v. orientalis, Fletcher, Proc. Linn. Soc, 

 N.S.W., xxii, 1898, p. 670 (part). 



Habit moderate. Head two -thirds as long as broad, 

 the measurement taken at a line drawn between the hinder 

 margins of the tympana. Snout rounded, a little longer 

 than the orbital diameter ; nostril elevated, sHghtly nearer 

 the tip of the snout than the eye ; canthus rostralis 

 distinct ; loreal region very obUque, concave. Tympanum 

 upright-oval, perfectly distinct, separated from the eye 

 by a distance equal to its own diameter, which is half to 

 two-thirds that of the orbit. Interorbital space almost 

 as broad as the upper eye-lid. Tongue broadly shield- 

 shaped or oval, slightly nicked behind. Vomerine teeth 

 in two fairly large, obhque, sometimes contiguous groups, 

 between the choanse. Limbs normal. Fingers tapering, 

 with a very fine fringe which is very slightly enlarged at 

 the bases between them so that it might be said that a 

 rudiment of a web is present ; if anything, this is best 

 developed between the first and second and second and 

 third fingers ; first finger slightly shorter than the second ; 

 discs swollen, but not enlarged, a little more than half 

 the transverse diameter of the tympanum ; sub-articular 

 pads tubercular ; several rows of tubercles on the 

 metacarpals : a large tubercle on the inner side of the 

 base of the first finger which may bear a brown rugosity 

 in breeding males. ' Toes moderate, not webbed to the 

 discs ; the third and fifth about three-quarters, the 

 fourth about two-thirds webbed, the fringe continuing to 

 the discs ; the latter small, if anything smaller than the 

 finger discs : a well developed inner metatarsal tubercle, 

 in adult specimens of quite an unusual sjze for a Hyla ; 

 sub-articular tubercles distmct and a row of smaller 

 tubercles on the under side of the phalanges and meta- 

 tarsals. Tibio-taisal articulation of the out-f tretched limb 

 reaching to the eye. Skin of back and hmbs warty above, 

 the vertebral region grooved and usually devoid of warts. 

 The warts usually commence, with a distinct line of
