BATRACHIAN3 AT PRESENT KNOWN TO INHABIT SIAM. 227 



Ruiia iiijrovif.tatu, Riiiu lateralis, Glijphojlossas mollossus, Calluella 

 ijutt'ilaia and Bafo parvus. The firb named I haarcl qalte recently 

 (luring a storm of rain, but of tlie otliers 1 liave liad no knowledge since 

 their introduction, and they may have died. 



As will be seen from the brief remarks attached to each species, 

 very few of those recorded are actually rare in the countr3'. The 

 majority are common, if not everywhere, at least in certain localities ; 

 and provided one knows liow and where to look for them, there is 

 usuall}' no difliculty in obtaining specimens. Frogs and toads are 

 chiefly nocturnal in their habits, and many have remarkable powers of 

 concealing tliemselves by day. The burrowing frogs, and the representa- 

 tives of the genm Me'juloiihrys, are noteworthy in this respect, and in 

 many localities I have onlj' discovered their presence by their tadpoles. 



In conclusion I sliould like to thank the following lady and 

 gentlemen for their kind and valuable assistance in collecting specimens 

 for me, and without whose help so complete a list could not have 

 been produced : — 



II. R. H. I'rince Abliakara of C'iininporn, Mrs. D. J. Collins, 

 Messrs. C. J. Aagaard, P. A. R. Barron, fJ. F. W Elwes, K. G. Gairdner,

 Kemp, A. L. Qaeripel, G. E. Webb, C. M. Weston, W. J. F. William- 

 son and H. C. St. J. Yates.

 used in my last list, (nnim p. 49).
