B. himalayanus. In the specimen of this sex nuptial asperities are present 

 on the first and second finger. 



Color (in alcohol) dark brown above, lighter below ; a blackish band begins 

 at posterior border of eye, covers the lower half of the paratoid gland, and runs 

 along the side, ending in a series of spots. In the female many of the warts 

 have black apices, a character frequent in B. melanostictus. 



Type. — No. 2432, Mus. Comp. Zool., two specimens, a male and female, 

 Bankoro, Central Formosa. Taken by a Japanese collector of Mr. Alan Owston. 



This strongly marked species is evidently closely related to Bufo melanostictus ; 

 it also tends towards Bufo himalayanus. This opinion is also held by Dr. 

 Stejneger, who has most kindly examined the types. 



Hyla kampeni, sp. nov. 



Tongue subcircular, slightly nicked and free behind. Vomerine teeth in two 

 short groups between the middle of the choanae, the interspace separating them 

 as wide as one of the groups. Snout rounded, tympanum round ; its diameter is 

 equal to two-thirds of the distance from eye to nostril. Rudiment of pollux 

 present. Fingers webbed as follows : second digit two-thirds, third wholly, 

 fourth almost wholly, fifth wholly. The toes are all wholly included in the extent 

 of the web. Discs large, almost as large as tympanum. Skin smooth above, belly 

 and lower side of thighs finely granulate. Upper surfaces greenish brown (dull 

 green in life), lower surfaces unmarked yellow. 



Type. — No. 2433, Mus. Comp. Zool., a single specimen, taken at Wahaai, 

 Ceram, January, 1907, by T. Barbour. 



Hyla kampeni is nearly related to H montana Peters e Doria. It may be 

 readily distinguished by its larger tympanum, greater extent of webbing between 

 the toes, and a more slender build. It is also evidently different from H. amboin- 

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

 locality. 



Recently Dr. P. N. van Kampen has produced (Max Weber's Zoologische 

 Ergebnisse einer Reise in Niederlandisch Ost-Indien, 1907, 4, pt. 2, p. 383-418, 

 pi. 16) a most excellent piece of work in which he tabulates the ranges of East 

 Indian Amphibians so far as they are known. He records Hyla dolichopsis Cope 

 and H. vagabunda Peters e Doria as the only ones hitherto known from the 

 island of Ceram. 



This species is named for Dr. van Kampen, friend and companion in travel in 

 the Dutch East Indies. 



Yan Kampen has shown (Nova Guinea, 5, Zoology, p. 176) in a recent ac- 

 count of New Guinea Amphibians that it is probable that the young of several 

 species of Hyla lack vomerine teeth. Is it not, then, also possible that this may 

 be the case with some adults ? Answering this in the affirmative he recommends 

 that Hyla and Hylella be united. He also notes that Gadow (Amphibia and 

 Reptiles, 1901) has remarked that owing to the wide discontinuity of the range of
