of the Bay of Bengal. 
narrow ; nine very long scabrous gill-rakers on the middle of 
the first branchial arch besides rudimentary ones above and 
below ; each pseudobranchia consists of two small pinnules. 
Head, body, base of pectoral fin, and basal two thirds of 
dorsal covered with small adherent scales ; between the base 
of the dorsal and the vent there are thirty rows. 
Dorsal fin much higher than the anal ; its rays, the longest 
of which are half the maximum body-height, are imbedded 
in a thick gelatinous tissue covered with scaly skin, in their 
basal two thirds. Caudal narrow, its length is a little more 
than that of the postrostral portion of the head ; it projects 
freely beyond the other vertical fins, with which it is con- 
nected only at its base. Pectorals entire, their bases fleshy 
and free, their rays long and delicate, reaching the origin of 
the anal fin. The ventrals arise behind and above the pectoral 
symphysis, their bases separated by an interspace about equal 
to | the diameter of the eye ; each consists of two short fila- 
ments, of which the outer is a little the longer. 
Stomach siphonal ; intestine much coiled ; no pyloric 
caeca; air-bladder developed; peritoneum deeply pigmented 
throughout. 
Colours in the fresh stale : — Body chocolate ; head, abdo- 
men, and all the fins black.

Head and body in spirit much compressed, but in the fresh 
state, owing to the presence of a uniform thick subcutaneous 
layer of mucus, rounded and subcylindrical ; tail long and 
tapering. 
Length of the head greater than that of the rest of the 
trunk, or about 5^ in the total without the caudal, the length 
of the entire trunk being about one third of the same standard 
and 2 | times the maximum body-height or head-depth ; an- 
terior third of the head somewhat abruptly depressed, its 
vertical profile forming an arc of a much smaller ellipse than 
that of the posterior part of the head. Snout depressed, 
rounded, somewhat inflated at the tip ; its length, which is 
less than its breadth, is one fifth the length of the head.
