Origin of first dorsal almost above that of ventrals. First spine 

 of first dorsal minute, hidden below the scales. Third spine 

 longest, not weaker than second one and about as long as 

 head. Spine of second dorsal somewhat longer or shorter than 

 snout and eye together and about as long as third or second 

 anal spine. Origin of second dorsal well in advance of that 

 of anal. Dorsals, anal and caudal scaly. Caudal very deeply 

 forked, with long pointed lobes. Pectorals pointed, straight, 

 their rays simple, very long, reaching to anal and exceeding 

 head by half its length. The four upper free filaments much 

 stronger and longer than the other ones, the upper three far 

 exceeding tip of caudal, the fourth one reaching about to tip 

 of caudal, the 5th reaching almost to end of base of anal, the 

 following ones diminishing in length, the fourteenth reaching 

 on ventrals. Ventrals somewhat longer than head without snout. 

 Distance between origin of ventrals and of anal exceeding 

 length of head by more or less than length of eye and snout 

 together. Colour of formol specimens bluish brown above, 

 yellowish white below; the myocommata shining through and 

 giving the appearance of light zic-zac cross bands. Fins yellowish. 

 Length 263 mm. 



Habitat: Sumatra (Djambi!); Borneo (Banjermassin, river 

 Kapuas; Sintang, Buniit!). — Siam. 



In rivers. 



Doubtful species. 



Von Martens mentions (Arch. f. Naturgesch. 34. Jahrg. 

 Bd. I. 1868, p. 13) Polyiieiniis paradiseiis L., a species from 

 the Indian Ocean, with the name of the species between brackets 

 and with a query from Borneo. It is probable, that VON 

 Martens' specimen belongs to a related species, as P. para- 

 diseiis has never been found in the indo-australian Archipelago, 

 although DUNCKER (Mitth. Naturh. Mus. XXI. 1904, p. 155) 

 mentions it from the Malay Peninsula (fishmarket of Klang).
