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

 dorsal. Pectorals equal to postorbital part of head, ventrals 

 slightly shorter. The thin, cycloid, deciduous scales, have their 

 hindborder irregularly rounded or somewhat pointed. Posteriorly 

 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. 



Habitat: Straits of Macassar (724 m.)! and Ceram sea 

 (567 m.) !

Height 5 ^ head a little less than 3. Head low and elongate, 

 tapering towards the front. Eye 3 ! / 4 , rather longer than pointed 

 snout, double of interorbital space. Jaws equal; maxillary 

 extends to below posterior third of the orbit. The dentition 

 feeble ; teeth small, pointed, of equal size, uniserial. Inter-

 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 

 uniform black. Length 225 mm. (without caudal). [After Giinther, 

 not seen by us].
