Philautus castanomerus (Bouleng.). 

 Ixalus castanomerus, Bouleng., Journ. F.M.S. Mus., I., 1905, 

 p. 39, pi. IV., fig. 1; F.M.P., p. 254. 



One example, Kuala Teku (No. 5929) ; one example 

 Wray's Camp (No. 5930). 



Boulenger's description, drawn up from a single 

 example, agrees entirely with these two specimens except 

 in colouration, a point of little significance with many of 

 the members of this genus, so greatly may they vary both 

 in colouration and in markings. 



No. 5930 has the snout obliquely pointed as in the 

 figure, the other, a larger one, has it more acutely pointed 

 owing to the presence of a distinct dermal tip. 



Both specimens are dark brown colour above, the 

 smaller one uniform, the larger with indistinct paler 

 mottlings and indications of a dark X ; below pale yellowish- 

 brown, heavily spotted with dark brown. 



Boulenger has compared this species with his 

 P. vermiculatus ; 1 can find nothing, however, except 

 colouration and a slightly narrower interorbital region, to 

 separate it from the Javan P. aurifasciatus Schlegel, with 

 a specimen of which I have compared it. 



Kalophrynus robinsoni, sp. nov. 



Type, author's number 5935, collected at Wray's Camp 

 in Oct. 1920 ; presented to the British Museum. 



Description of the type. Tongue elliptic, entire. 

 Snout short, truncate, projecting slightly beyond the 

 mouth ; canthus rostralis distinct, loreal region vertical, 

 feebly concave ; interorbital region broader than the upper 

 eyelid ; tympanum distinct, two-thirds the diameter of the 

 eye. First and second fingers very short, not half the length 

 of the third, fourth shorter still ; toes one-third webbed, 

 the web extending as a fringe along the outer sides of the 

 toes ; fifth toe shorter than the third ; tips of fingers and 

 toes bluntly pointed ; a feebly developed oval inner 

 metatarsal tubercle and a rounded outer one. The tibio- 

 tarsal articulation reaches the tympanum. 



Skin of the back granular, with small scattered 

 tubercles ; a series of tubercles along the dorso-lateral 

 region from the eye to the groin ; belly and groin with 

 large, coarse granules ; throat with finer granules ; a 

 curved fold from the eye to the shoulder. 



Light brown above with dark brown markings, in 

 particular a large one on the back extending forwards in 

 two branches to the eyelids, and backwards, in two longer 

 branches to the groins ; sides of head and body very dark 

 brown, this colour sharply defined from the light brown
