898 SIR. S. S. FLOWER ON THE HEFriLES AND [DeC.l, 



Mr. Hervey. A Prog in the Eafflea Museum, Singapore, labelled 

 " Malacca," is apparently of this species, but it is iu a bad state of 

 preservation, and the back is quite smooth, without the tubercles 

 which are present in Mr. Hervey's specimen ; both are females. 

 Hah. Indiii, Malay Peninsula.

As first pointed out by Mr. Blanfoi-d, there seem to be two varie- 

 ties of this species, very diiierent in appearance. The specimens I 

 collected at Penang are so different from those I got at Singapore, 

 as to appear to be of distinct species : but on comparing them 

 with the large series in the British Museum from many different 

 localities in the East Indies, I cannot find any constant characters 

 by which to separate the two varieties. 



Stoliczka found this species in the collection he got from Penang 

 and Province Wellesley, but from his description one cannot tell 

 to which variety his specimens belonged. P. Miiller mentions a 

 specimen of liana macrodon (Giiiith. Cat. Batr. p. 8) from Malacca 

 in the Bale Museum (Verb, naturforsch. Ges. Basel, vii. 1882-85). 



The following description will, I trust, be of use in identifying 

 this Frog : provisionally I have called the broad-headed form the 

 Singapore variety, and the narrower-headed the Penang variety. 



Vomerine teeth on two straight ridges running obliquely back 

 from the anterior angle of the choante, and converging behind so as 

 to meet, if prolonged, nearly in a right angle, but rather widely 

 separated ; a strong osseous transverse ridge behind the choanaB ; 

 lower jaw with two fung-like bony prominences in front, fitting 

 into hollows inside the Hpi)er jaw ; when the mouth is closed, the 

 size to which these prominences are developed is variable. 



Head large, this is especially so iu the adults of the Singapore 

 variety. In the typical Penang variety the snout is usually 

 pointed, but very vaciable in shape ; in the Singapore variety it is 

 broad and rounded at the end. Blanford says of the snout of the 

 Singapore variety, " no trace of canihus rosiralis,' but in my speci- 

 mens, though but slightly developed, it is at once apparent ; no 

 constant distinction can be made between the two varieties in 

 regard to the amount of depression of the snout. Occiput more 

 or less swollen at the sides. The nostrils are nearer the end of 

 snout than the eye ; their distance apart in the Penang variety is 

 equal to or greater than the interorbital space, while in the Singa- 

 pore variety it is considerahly less : this character will be found 

 useful in distinguishing between (he two varieties, but it does not 

 hold good for young specimens. In all seven Penang specimens 

 the breadth across the gape is about equal to the distance from 

 angle of mouth to end of snout, and considerably less than the
