along the middle of the back, and an other along the base 

 of the anal, the two of both sides united into one behind that 

 fin, and running to the lower base of the caudal. Fins hyaline. 

 The caudal lobes with a subterminal black band, and a darkish 

 hue at its base. Length 150 mm. 



Habitat: Sumatra (rivers Musi, Kampar !, Lala, Indragiri !, 

 pond near Deli !) ; Borneo (Senah, Sarawak !, river Kapuas, 

 river Sebuku !). 



Note: We unite with the present species the specimens 

 described by BoULENGER as R. calliura from Senah, Sarawak, 

 Borneo. We have seen them in the British Museum as also 

 identical specimens from river Sebuku, North East Borneo, 

 belonging to the Museum in Buitenzorg, Java. The only difference 

 is that in R. trilineata the black blotches on the lobes of the 

 caudal are subterminal, in R. calliura they cover also the tips 

 of the lobes of the caudal. This difference is not a geographical 

 one, as VAILLANT has described specimens from Borneo with 

 subterminal black blotches on the caudal lobes.

 Mus. Hamburg, XXI. 1904, p. 182. 



Differs from the preceding species in having only 10 scales 

 in frout of the dorsal and in wanting the black bands on the 

 caudal. At the other hand the dorsal is deep black in the 

 middle of its anterior part. Measurements, position of fins and 

 colouring are equal for the rest in both species, when specimens 

 of equal length are compared. In the diagnosis of this species 

 DUNCKER says: "Lin. lat. unvollstandig". This must be a 

 misprint, as the L. 1. in clearly indicated on the figure accom- 

 panying DUNCKER'S description and as it is] very distinct in 

 typical specimens, which Dr. DUNCKER kindly sent us for 

 examination. Length about 45 mm. 



Habitat: Sumatra! Malacca!.
