of moderate length. Mouth small, subinferior, subhorizontal ; lips 

 thin. A pair of maxillary barbels. Pharyngeal teeth hooked,

D. 10. A. 9. V. 8. L. lat. 46-48. L. transv. ^. 



The height of the body is about one-fourth of the total length 

 (without caudal), the length of the head two-ninths ; the diameter 

 of the eye equals the length of the snout, and is contained thrice and 

 three-fourths in that of the head. Barbels scarcely shorter than the 

 eye. Origin of the dorsal fin nearer to the root of the caudal than 

 to the end of the snout ; its spine is longer than the head. (BlJcr). 



China. 



This fish may prove to be identical with Leticiscus xanthurus, 

 Richards. Ichth. Chin. p. 298, named from a rather coarse drawing 

 in the British Museum. 



55. MYSTACOLEUCUS. 



Systomus, sp., Bleeker. 



Scales of moderate size ; lateral line running along the middle of 

 the tail. Dorsal fin short, with an osseous, serrated spine, inserted op- 

 posite to the ventral. Anal fin of moderate length. Mouth anterior, 

 with the margin of the lower jaw obtuse. Barbels twoi Gill-rakers 

 short, conical ; the gill-opening extends to below the angle of the prse- 

 operculum. Pharyngeal teeth obtusely uncinate, 4.3. 2 — 2 .3.4. 



Sumatra. 



Although the type of this genus agrees in other essential points 

 with Barhus, it differs from it in a very remarkable manner in the 

 development of the anal fin ; it may be regarded as an intermediate 

 form between Cyprinina and Xenocypridina.

D. 12. A. 11. L. lat. 38-39. L. transv. 7/5. 

 The osseous dorsal ray is of moderate strength and serrated. 

 Mouth rather narrow. The height of the body is contained thrice 

 and one-third in the total length (without caudal), the length of the 

 head four times. There are three longitudinal series ot scales be- 

 tween the lateral line and the root of the ventral fin. Coloration 

 uniform.
