 opening or a little longer. Ventrals about half as long as 

 pectorals, their base a little nearer to head than to caudal. 

 Caudal rounded. Colour yellowish with a fine dark lateral line 

 on the body, accompanied in the posterior part of the body

Habitat: Borneo (river Meridan!); Celebes (Makassar, 

 Maros!, river La-Palupa near Tempe!, Luwu !, river Kalaena, 

 river Toka near Paloppo, stream between Enrekang and 

 Batu lappa). 



In rivers. 



Note. The specimens from Borneo have a little longer 

 head, when specimens of the same size are compared, but we 

 don't think this sufficient reason to increase the number of 

 species of Dennogenys, the characteristics of which are already 

 not sharply defined.
