site to origin of dorsal. Origin of anal opposite to middle of

they get smaller and are wanting on the fins. About 25 slender 
gillrakers on the first branchial arch. Colour nearly uniformly 
bluish black. Length 265 mm.

Height 5'/,, head a little less than 3. Head low and elongate. 
tapering towards the front. Eye 3'/,, rather longer than pointed 
snout, double of interorbital space. Jaws equal; maxillary 
extends to below posterior third of the orbit. The dentition

vomerine series divided into two groups, each with three 
teeth. Palatine series short, consisting of about nine teeth. 
Gillrakers long, lanceolate, rather widely set, 22 on the outer 
branchial arch. Vent nearly midway between gillopening and 
root of caudal. Origin of dorsal somewhat in advance of vent, 
its last ray opposite to the fourth of the anal. Both dorsal 
and anal rather high in front, their longest rays being equal 
in length to the depth of this portion of the body. Ventrals 
covering the vent, but not extending to the anal; their base 
is midway between the root of the pectoral and the end of 
the anal, immediately in advance of the dorsal. 
Scales simple, cycloid. Lateral line straight, running along 
the middle of the tail, with wide mucous apertures. Colour
