AMPHIBIA. 77 



hoinensis Horst and H. ruepelli Boettger, which we might expect to find in this 



locality. 



Hyla dolichopsis (Cope) and H. vagabunda Peters and Doria are the only 



other members of the genus which have been previously reported from the island 



of Ceram. 



Hyla (Hylella) ouwensii Barbour.

 Bull. M. C. Z., 1908, 61, p. 325. 



"Head short; snout squarish; loreal region rather concave; tympanum 

 extremely small, about one fifth diameter of eye; the tibio-tarsal articulation 

 reaches a considerable distance beyond the snout. Fingers two thirds webbed, 

 toes three fourths webbed. Skin of back rough, but without enlarged tubercles, 

 skin on belly with very many small tubercles; these are largest and most abun- 

 dant about the anal region, whence the series extends out onto the inner sides of 

 the thighs for about half their length. Upper parts of head, body, thighs, shins, 

 feet, and arms of a grayish ground color vermiculated and blotched with blue, 

 in alcohol, green in life; more ashy gray shows on the limbs than on the back. 

 Throat white, belly and lower sides of hind limbs yellowish. 



Allied to Hyla (Hylella) nigromaculata (Meyer). 



Type: — No. 2434, M. C. Z., a single specimen, about an inch and a half 

 long, taken at Pom, north coast of Jobi (Japan) Island, Geelvink Bay, Dutch 

 Papua, February, 1907. T. Barbour, collector." 



Two other species of this genus, also lacking in vomerine teeth, have been 

 described from Jobi Island; while from the great '' mainland" of Papua but a 

 single species is known. In the preliminary paper (loc. cit., p. 324) I pointed out 

 why these species might advantageously be included in the genus Hyla. Van 

 Kampen (Nova Guinea, 1906, 5, 6, p. 176) showed that certain true Hylas lack 

 vomerine teeth in the young condition. As this might, therefore, be a character 

 which persisted in some species, and as Hylella from its distribution could not 

 be considered a monophyletic genus, it seemed wise to combine the two groups, 

 as van Kampen suggested.
