 Height 3 1 /-, about 4 in length with caudal. Head 4 2 / 5 , 5 3 / 4 in 



length with caudal. Eye 3 3 / 4 , shorter than snout, nearly twice 

 in interorbital space. Snout scarcely prominent, without pores; 

 maxillary barbel about as long as eye, the rostral one much 

 shorter. Origin of dorsal separated by 12 scales from occiput, 

 situated before ventrals; dorsal gradually increasing, ending 

 conspicuously before origin of anal, its height i 2 / 5 in height of 

 body. Anal not emarginate, much lower than dorsal. Ventrals 

 not reaching anal, separated by 4 ! / 2 longitudinal series of scales 

 from lateral line, shorter than pectorals, which do not reach 

 ventrals and go 6 ! / 2 times in total length. Caudal deeply incised, 

 lobes pointed, longer than head. Silvery, back greenish; a black 

 band, about as broad as a scale, anteriorly narrower than 

 posteriorly, runs along the lateral line to the end of the middle 

 caudal rays. Length of the single specimen described 198 mm. 

 [After BLEEKER and GUNTHER; not seen by us].

 length with caudal. Height of head about equal to its length. 

 Eye about 3, slightly shorter than snout, situated about in 

 the middle of the length of the head, 1.6 in convex inter- 

 orbital space. Snout blunt, scarcely prominent, without pores. 

 Lower jaw obliquely ascending from chin. Maxillary barbels 

 about equal to eye and much longer than the rostral ones. 

 Origin of dorsal opposite to Qth scale of lateral line, separated 

 by 10 scales from occiput. Dorsal with the anterior rays scarcely 

 prolonged, somewhat longer than head. End of dorsal above 

 anal. Anal somewhat concave, the anterior rays prolonged,
