600 ON BORNEAN REPTILES AND AMPHIBIANS. [Apr. 16, 



POLYPEDATES GUTTATUS (Gthr.). 



Having received two other specimens of Ixalus guttatus, I see 

 that the typical specimen is not full grown, being only 30 mm. long. 

 No trace of vomerine teeth are visible in it ; whilst two short tooth- 

 bearing ridges obliquely diverging backwards are present between 

 the inner nostrils of the old specimens. The body of the latter is 

 47 mm. long. Polypedates raniceps appears to be closely allied to 

 this species, but to have a larger tympanum. 



Polypedates signatus. (Plate XL. fig. C.) 



Somewhat similar in habit to Polypedates guttatus, but with the 

 snout shorter ; canthus rostralis distinct, loreal region vertical, con- 

 cave ; eye large ; tympanum about one half the size of the eye. 

 Back and sides granular, lower parts smooth. Fingers very slender, 

 quite free, with very small disks ; toes slender, two thirds webbed, 

 with small disks ; two small metatarsal tubercles. Inner nostrils 

 narrow, narrower than the Eustachian tubes ; vomerine teetli in two 

 oblique converging series between the inner nostrils. Upper parts 

 black ; a light olive band runs along the upper margin of the snout 

 and eyelid, and along each side of the back, the back itself being 

 spotted with reddish olive, as are the sides ; upper parts of the legs 

 with black cross bands ; lower parts whitish.
