rudimentary on the lower jaw. Teeth in narrowish villiform 

 bands in jaws, vomer, and palatines. Tongue large. Oro- 

 branchial cavity intense black throughout. Gill-opening 

 moderately wide, the membranes rather broadly united below 

 the isthmus anteriorly ; gill-laminje very narrow ; ten long 

 pointed scabrous gill-rakers on the first branchial arch, 

 besides some rudimentary ones above and below. 



Head and body covered with small deciduous scales ; 

 apparently 22 rows between the dorsal fin and the vent. 

 Lateral line indistinguishable. 



Vertical fins united ; the dorsal begins just behind the 

 vertical through the base of the pectoral, its longest rays — 

 about the middle of the fin — are rather over one third the 

 maximum body-height and exceed the corresponding anal 

 rays in length. Caudal long and pointed. Pectorals entire, 

 pointed, as long as the head without the operculum. Ven- 

 trals jugular, arising from bony bases which are distant by 

 a wide interspace equal in width to one third the length of 

 the head ; each consists of two filaments, of which the inner 

 is much the longer, reaching beyond the origin of the anal 

 fin. 



A bunch of about six slender cseca situated above the 

 pylorus. Air-bladder present. 



Colours in the fresh state : — Uniform chocolate ; fins 

 blackish ; throat and belly black, owing to the pigmentation 

 of the peritoneum. 



Total length 4^^ inches.

When brought on board the skin of the head was injected 

 and spotted with small capillary hasmorrhages.

Length of the head about one fifth of the total, its heio-ht 

 about two thirds, its breadth not quite half, its length. 

 Snout subtrihedral, its length almost equal to the diameter 

 of the large circular eye, which is about one fourth the lenoth 

 of the head ; interorbital space slightly convex, its widtli 

 one fourth greater than that of the eye. Nostrils close 

 together in front of the angle of the eye, the posterior very
