strongly concave and scaly. Pectorals about as long as head, 

 reaching to origin of first dorsal; their axillary scale shorter 

 than half length of fin. Axillary scale of ventrals longer than 

 half their length. Caudal emarginate. Least height of caudal 

 peduncle about equal to postorbital part of head and nearly 

 one fifth shorter than length of peduncle. Silvery with a greyish 

 back, fins hyaline, axil of pectorals with a dark spot. Length 

 200 mm. [Specimens of BLEEKER'S collection in the Leiden

Rostro-dorsal profile more or less convex. Height about 

 equal to head, 4.2 to more than 5 in length, caudal included. 

 Eye 3.4 3.8 in length of head, which is rather obtuse and 

 twice or somewhat less in postorbital part of head; gelatinous 

 membrane anteriorly and posteriorly well developed. Inter- 

 orbital part of head slightly convex, more than 2 1 / 2 times in 

 length of head. Snout obtuse, convex, shorter than eye. Prae- 

 orbital bone scaly, rather small, not curved or emarginate. 

 Maxillary visible, exceeding posterior margin of praeorbital, 

 the denticulation of which is nearly invisible. Symphysial knob 

 nearly simple. Origin of first dorsal separated by about 20 

 praedorsal scales from snout, much nearer to end of snout than 

 to base of caudal and opposite to 1 2th lateral scale. Dorsal spines 

 moderately strong, about equal to length of postorbital part 

 of head, about as high as second dorsal, which is lower than 

 anal, the base of which is much longer than second dorsal. 

 Both fins are covered by small scales and deeply concave. 

 Origin of second dorsal opposite to 25^ 26 tn lateral scale 

 and to first third of anal, the origin of which is opposite 

 to 2 y& or 24th lateral scale. Caudal emarginate with acute 

 angles. Pectorals about equal to length of head or in adult
