spines are in close contact with each other and with the rest of the fin. Caudal 

 symmetrically forked. Pectorals pointed, their length rather more than four- 

 fifths the height of the body. Ventrals much shorter than the pectorals ; they 

 are adherent to the abdomen throughout their inner border, and can be retracted 

 within a shallow furrow in the middle abdominal line. 



Peritoneal cavity large, the membrane black ; numerous pyloric caeca in an 

 arborescent mass ; no air-bladder. Vertebra? 10/14. 



Colours in life, uniform bluish black, with an uneven silvery sheen. 



In the Indian Museum are four adult specimens, the largest being nearly 

 7 inches long, from off the Ganjam coast 98-102 fathoms and off the Godavari 

 coast, 240-276 fathoms.

 rays.

 of preoperculum serrated. Six branchiostegals. Pseudobranchire present.

The height of the body varies with age : in adults it is greater than the 

 length without the caudal, in specimens about a third grown it equals the length 

 of the body to the beginning of the caudal peduncle.
