(counted in greatest height). 



Height 4.8 5, 6.2 6.4 in length with caudal. Head about 

 3.8, 4.8 in length with caudal. Eye 4, about i 1 /,, in snout and 

 in interorbital space. End of maxillary reaching to below 

 pupil. Rostral barbels somewhat longer or shorter than the 

 lower ones, which are somewhat shorter than half head. Origin 

 of dorsal above 23 r <* 24^1 scale of lateral line, separated by 

 23 to 25 scales from occiput. Dorsal concave, its height equal 

 to height of body. Anal concave, its height slightly less than 

 that of dorsal, its origin opposite to 26 th scale of lateral line. 

 Ventrals with the outer rays produced into long filaments, 

 reaching far on anal, their origin separated by 2 2*/ 2 scales 

 from 13^ or 14^ scale of lateral line. Pectorals about equal to 

 length of head, reaching on ventrals. Caudal deeply forked, 

 the lobes pointed, about equal to head. Least height of caudal 

 peduncle less than half its length, surrounded by 12 scales; 

 before and behind that height they are surrounded by 14 

 scales. Yellowish brown, back darker. A blackish band along 

 the middle of the side, indistinctly beginning at the snout and 

 continued, increasing in breadth and intensity, into an intra- 

 marginal band on the upper caudal lobe. The lower lobe with 

 a similar band. The anterior part of the lateral band may be 

 composed of spots in young specimens. An irregular series 

 of few small black spots in the anterior half of the lateral 

 line. Length more than 265 mm. 



N o m. i n d i g. : Wader (Javan.); Djohar (Djambi); Lukui (Bulit). 



Habitat: Sumatra (Solok, Sidjungdjung!, Lahat, Batang 

 Hari: Djambi!, Semangus, tributary of river Musi); Java 

 (Batavia, Bekassi, Rankasbetong, Lebak, Kediri!, Surabaya, 

 Gempol) ; Borneo (river Kapuas, river Bulit, affluent of river 

 Bongan). - - Malacca. 



We believe that the differences between L. weberi and 

 L. setigerum (smaller eyes, longer dorsal, pectorals and ven- 

 trals) are due to age.
