 45- Notopterus borneensis Bleeker. 



Head 4yL; depth 3f ; D. ii, 7; A. about 122. liength 17^ inches. 

 One example. 



Bleeker gives a good figure^* of this species, but my example differs 

 in having the spots more numerous, smaller, extending the whole 

 length of the anal and also above the lateral line on the end of the trunk. 

 The spots on the trunk are also a little larger than those on the anal. 

 The upper profile of the head is a little more concave and the end of 

 the maxillary a little more posterior.
