13, 1878, pl. 6 fig. 2, the disks of the fingers and toes are considerably smaller in H. 
arfakiana than in my specimen. Hyla parvidens has vomerine teeth hardly distin- 
guishable, considerably shorter hind limbs, a quite different colour etc. 
Hyla serrata n. sp. 
(Fig. 6.) 
Tongue broad, oval or semicircular, nicked behind. Vomerine teeth in two 
small oblique groups on the level with the hind edges of the choan&e. Head rather 
small, as broad as the distance between the tip of the snout and the hind margin 
of the tympanum. Snout rounded, in the adult distinctly longer than the orbital 
diameter; canthus rostralis distinct, loreal region high and oblique, not concave. 
Interorbital space broader than the upper eyelid; tympanum very distinct, small, 
more than one third, but not half, the diameter of eye. Three outer fingers more 
than half webbed, the web extending to the disks as broad folds along the distal 
joints; web distinct between the base of the first and second fingers as well. No 
distinet rudiment of pollex. Toes nearly entirely webbed, the web does not reach 
the disk of the fourth toe; an oval inner metatarsal tubercle, no outer; a very 
distinct, serrated dermal fold along the outer edge of the tarsus and along the outer 
side of the fore-arm. The disk of the fourth toe about as large as the tympanum, 
that of the third finger somewhat larger. If the length of the tibia is marked from 
the knee forwards along the body, it reaches the tip of the snout or somewhat beyond. 
All upper and lower surfaces coarsely granulate; besides, the upper parts are provided 
with small scattered tubercles. A distinct fold above the tympanum. Colour in 
spirit: upper parts rather variable; the largest specimen light grey, indistinetly spotted 
with black; the smaller specimens either dark olive, uniform or more or less marbled 
with brownish grey, or reddish brown, marbled with dark olive. Generally, the 
colour of the limbs resembles that of the body; in one of the small specimens the 
limbs are considerably lighter, densely and minutely dotted with brown; in two others 
the hind limbs are provided with two light bars across the thighs and tibie. Under 
surfaces uniform light grey, sometimes the chin and the feet are dusky grey. According 
to a statement of Dr. MJÖBERG, the colour changes in a very high degree in agree- 
ment with the haunts of the animals. Regarding the specimen figured he says: 
»This specimen resembled completely the branch of the tree, on which it was sitting 
when caught.» 
Six specimens collected during the rainy season (January to May) 1913; two 
(17,5 and 74 mm.) at Carrington, three (45, 42, 38 mm.) at Malanda and one (43 mm.) 
at Atherton.
