Second dorsal spine from a half to two-tliirds the length of the head. The 

 upper pectoral rays vary from about two-thirds (adults) the length of the head 

 to the entire length of the head (young). The outer ventral ray is about equal 

 to the post-orbital portion of the head in the adult, but is equal to the post- 

 rostral portion of the head in the young. 



There are 20 very large pyloric C£eca. 



The longest specimen is 20:j inches in length. 



Arabian Sea, 406, 480, 719 fathoms ; Gulf of Manar, 142 to 400 fathoms ; 

 Bay of Bengal, 410 fathoms ; Andaman Sea 405 fathoms.

This species may possibly be identical with B. melanobranchiis Vaillant. 



Family Ateleopoclidce. 



Head rather large, with the muciferous cavities fairly well developed ; 

 trunk short ; tail long, compressed, gradually tapering to a filament. 



A single, short, dorsal fin, situated above the pectorals. A long anal 

 fin, continiious with the caudal. 



Ventrals jugular. 



No pseudobranchiae : no air-bladder : no pyloric appendages. 



This is another family which has been found to range into Indian waters 

 since the publication of the Fishes and Fauna of India.

Skeleton semi-cartilas-inous. 



O 



The snout projects well beyond the mouth, which is small, quite inferior 

 and strongly protractile downwards. Teeth villiform, minute ; in a band in the 

 upper jaw only, or in both jaws : palate smooth. No barbel. 



Gill-openings fairly wide, the gill-membranes slightly united anteriorly. 

 The first branchial arch is rather broadly connected, at its upper part, by mem- 

 brane, with the wall of the gill-chamber, so that the slit between that arcla and 

 the gill-cover is narrower than the other branchial clefts. Gill-rakers on the 

 outer side of the first branchial arch cartilaginous, tuberculifonn. Eight bran- 

 chiostegals. 



Head and body covered with a thick, gelatinous, scaleless skin. 

 The ventrals arise immediately behind the clavicular symphysis : each con- 

 sists of a single stout filament made up of two intimately coherent rays. 

 Distribution : Japan, Andaman Sea, Laccadive Sea.
