Scales in twenty-five or twenty-seven, rarely in twenty-nine series. Ventrals 140-156; 

 subcaudals 26-37. Anterior frontal much longer than broad, rather smaller than one of the 

 posterior frontals ; vertical six-sided, as long as broad, broader behind than in front ; super- 

 ciliary narrow ; occipital longer than vertical, rounded behind ; nasal larger than a posterior 

 frontal ; one prseocular, two postoculars. Five large upper labials, the thu-d of which enters 

 the orbit. Temporals 2 + 3; only the upper anterior temporal is in contact with the post- 

 oculars. Two pairs of subquadrangular short chin-shields, subequal in size. Uniform 

 blackish ash above, the lower parts and the three outer series of scales whitish. 



We have received numerous examples of this species from Borneo, Ceram, and Pinang, 

 where it is common in fresh waters as well as for some distance out at sea. It attains to a 

 length of 25 inches, the tail measuring 3 inches. It is of sluggish, not fierce, habits. I 

 have found only Crustacea in its stomach, but Cantor has found fishes also. A female dis- 

 sected by me had fully developed embryos in its oviduct. 



Fordonia leucobalia, Schleg., from Timor, appears to differ in its coloration only, having 

 white spots across the back.
