NEW REPTILES AND A NEW BATRACHIAN FROM SIAM. 225 



Reia'irkg. Tliis species is described from examples (about 5U) taken 

 at Prachuap last November, liaving just emerged from the tad[>ole stage, 

 and since kept by me alive. The practice of describing from specimens 

 reared in captivity is, I believe, not a sound one, as certain modifica- 

 tions from the normal, particularly of the tips of the fingers and toes, 

 and in the amount of webbing to the feet are liable to occur under the 

 altered conditions. In this case, ho\vever, confii niatioii has been obtained 

 from another specimen found at Nong I'ling, near Palcnampo, Central 

 Siam, some 400 kilometres north of Pi'achuap. The length of this 

 specimen is 88 mm. from snout to vent. 



In both localities this frog was found in company with its ally 

 C. palchra, and with two other species of burrowing frog, Gh/jihu- 

 fllu.isus molossus and Calluelia ijidlulala. Callalu iiietUulineala, however, 

 appeared to be considerably rarer than either of the otlier three, 

 as in spite of the most diligent search on the same ground on 

 many occasions since, only the one adult specimen has ^o far been 

 obtained. 



My Siamese collector says he is familiar with this frog, and that 

 it occurs in tlie country round Ubon. It is known tiiere as the 

 " eung mawliai ", and is eaten by the country people. 



I wish to thank Jlr. G. A. Boulenger, F. R. S., of the Britisli 

 Museum of Natural History, for his kind assistance in the determina- 

 tion of the two lizards; and Dr. Annandale, D. Sc, of the Indian 

 Museum, Calcutta, and Mr. N. 13. Kinnear, of the Bombay Natural 

 History Society, for sending me specimens of Russell's \'iper from 

 India and Burma to compare with mj' own from Siam.
