At a first glance this frog appears to have a great resemblance to Hyla rhaco- 
phorus from New Guinea, described by KAMPEN in Resultats de V Expedit. Sc. Neerl. å la 
Nouvelle-Guinée, Vol. 9, Zool. Liv. 1, p. 32, Leiden 1909. The very distinct serrated 
dermal folds along the fore-arm and hand, and tarsus and foot give the same charac- 
teristic appearance to that species as to the one here described. In addition to this 
H. rhacophorus has »auf der Oberseite von Kopf, Rumpf und Extremitäten zerstreute 
kleine Warzen; etwas grössere Warzen unter dem After (hier z. T. in einer Querreihe 
angeordnet) und an den Fersen». This description corresponds well with my new 
species, except that the latter is still more warty than the figure of H. rhacophorus. 
A closer examination of KAMPEN's description and figure clearly proves, however, that 
my specimens can not be referred to his species, which has a small head ('/s the 
length of head and body), canthus rostralis sharp, loreal region deeply concave, inter- 
orbital space as broad as the upper eyelid, tympanum ”/s the eye, considerably larger 
web on the hand as well as on the foot, disks smaller than the tympanum, upper 
surface »>»bläulich violett, Unterseite gelblich>, in addition to which »Oberarm und 
Oberschenkel mit Ausnahme eines schmalen Streifens längs der Oberseite, die drei 
inneren Finger, der Tarsus und Fuss, das Trommelfell und der Lippenrand» are »gelb- 
lichweiss>. 
By the well developed web on the hand and the small tympanum it also 
appears to be allied to Hyla montana PETERS & DoRriA, H. rippellt BoETTGER and 
H. mystax KAMPEN. 
H. montana differs in having the skin of the upper parts smooth, the vomerine 
teeth situated between the choan&, and, to judge from the figure in Ann. Mus. Civ. 
Genova 13, 1878, pl. 7, f. 1, no fold on the fore limb and only a faint one on the 
tarsus. 
Hyla riippelli has the upper surfaces smooth, still smaller tympanum and smaller 
disks (BOETTGER states, that in a specimen 45 mm. in length tympanum is only 2
