connecting end of snout and base of caudal, separated by 14 

 scales from occiput. Dorsal somewhat emarginate, but with 

 the last ray prolonged. Third spine rather weak, its total length 

 nearly ! / 3 more than length of head. Anal emarginate, the 

 anterior rays prolonged, nearly equal to length of head and 

 reaching outer rays of caudal; its origin opposite to 28 th or 

 2gth scale of lateral line. Ventrals */4 longer than head, the 

 outer rays prolonged, nearly reaching anus; their origin opposite 

 to the 15 th or i6 tn scale of lateral line, from which they are 

 separated by 5 ! / 2 scales and opposite to the 6*h branched ray 

 of dorsal or nearly to the middle of that fin. Pectorals falciform, 

 longer than head. Caudal deeply bifurcate, the lobes pointed, 

 much longer than head. Least height of caudal peduncle nearly 

 equal to its own length, i ! / 2 times in that of head, surrounded 

 by about 19 scales. Silvery, back darker. Twelve to fifteen 

 scales above the pectoral, arranged in 2 3 vertical rows, with 

 a more or less extensive brown blotch. Length of specimen 

 described 432 mm. 



Nom. indig. : Tiam. 



Habitat: Sumatra (Kota Radja, Chinese fishpond !). China. 



We suppose that our specimen is identical with the species 

 scantily described by VALENCIENNES and by RICHARDSON 

 after drawings only. It has probably been introduced by Chinese.
