namely Macrurus with 16 species, and Bathygadus with 

 2 species. Macrurus cavemosus, which is not uncommon 

 in the Andaman Sea and Gulf of Manar at ISO to 405 

 fathoms, also occurs in the Gulf of Mexico, and is very 

 probably identical with the Mediterranean Macrurus 

 italicus. Macrurus la-vis, of which several specimens 

 have been taken in the Andaman Sea at 188 to 419 

 fathoms, and in the Arabian Sea at 719 fathoms, also 

 occurs in all parts of the North Atlantic system, off the 

 coast of Brazil, off Madeira and its neighbourhood, in 

 the Mediterranean, and off the Sandwich Is. Bathygadus 

 longifilis is another Indian species that is found off 

 the Atlantic coasts of America, and in the Madeiran 

 neighbourhood. 



Family IV. Atcleojyodidce [Case 42]. 



Two closely similar species, one from the depths of 

 the Indian seas, the other from Japan, make up this 

 family. The body is shaped like that of Afacrurus, 

 but there are no scales and the ventral fins are reduced 

 each to a single stiff filament. In the Indian species, 

 Ateleopus indicus, the mouth looks as if it were adapted 

 for suction : this species has been found in the Anda- 

 man Sea, at 188 to 405 fathoms, and off the Malabar 

 coast, at 224 to 284 fathoms. 



Anacanthini Pleuronectoidei. 



This section includes the single large family of Pleuro- 

 nectidas or Flat-fishes. 



Family V. Pleuronectidce [Cases 42, 43]. 



In the Flat-fishes the head and part of the body 

 have departed from the bilateral symmetry that charac- 

 terizes all the Craniate Vertebrates.
