 somewhat convex. Height 4 l / 2 . Head 3 3 / 4 in length without caudal. 

 Eye less than 4, with a circular membrane, slightly longer than 

 snout. Interorbital space convex, a little more than diameter 

 of eye. Snout acutely convex. Praeorbital pentagon, anterior 

 inferior and lower posterior border straight, upper borders 

 strongly concave, longer than the inferior borders, both united 

 in an acute angle, looking towards the nostrils. Jaws even 

 anteriorly, maxillary reaching to the vertical from the orbit. 

 Lips slender. Two maxillary barbels, shorter than eye. Origin 

 of dorsal somewhat in advance of the ventrals and nearly 

 midway between the end of the snout and the root of the 

 caudal. Dorsal scarcely emarginate, its height not much less 

 than that of the body. Second simple ray slender, not osseous, 

 flexible. Anal scarcely emarginate, lower than dorsal. Simple 

 rays not osseous and very slender. Ventrals and pectorals 

 subequal, about ? l / 2 times in length, slightly longer than post- 

 orbital part of head. Ventrals not reaching anal, separated by 

 2y 2 series of scales from lateral line. Pectorals ending at some 

 distance from the ventrals. Caudal deeply incised, its lobes 

 acute, about 4 2 / 3 in length [after BLEEKER] 2 ). Least height of 

 caudal peduncle a little more than twice in head and 1.4 in its own 

 length. Free part of scales longitudinally and somewhat radially 

 striated. Lateral line straight, the tubes simple, reaching the 

 free border of the scales or nearly so. Colour in spirits brown 

 with a distinct silvery band from head to caudal, broadest

1) In the description of BLEEKER in Atlas Ichthyologique 1. c. the number of 

 the pectoral rays is erroneously given as 1.17. 



2) In the only available specimen the caudal is wanting.
