The peritoneum is of an intensely black colour ; the stomach horse- 

 shoe-like bent ; the pyloric appendages are exceedingly numerous, 

 thin, and many of them bifid or trifid ; the intestines make five com- 

 plete convolutions, and are 1| as long as the whole fish; the uir- 

 bladder is posteriorly divided into two large horns, situated between 

 the mupcles of the tail and the ha)mal spines belonging to the anal fin. 



Skeleton. — The occipital crest is elevated, triangular, and does not 

 extend on the frontal bones. The frontal bones are broad, and fur- 

 nished -ndth two low elongate protuberances, which diverge between 

 the eyes, each terminating in two crests, lateral to that of the occi- 

 pital, and moderately developed ; the nasal (ethmoid) bone is not 

 concealed by the frontal bones, and projects considerably before 

 them. The anterior portion of the intermaxiUaries is strong and 

 thick ; their posterior processes equal in length the descending 

 branches. The maxillary is feeble, with a broad free extremity. 

 The mandibula is short, elevated, and about as long as the prajor- 

 bital. The head of the vomer is triangular and slightly excavated. 

 The turbinal bone is very elongate and tubiform, the pra^orbital 

 rhombic, the suborbital arch narrow, with a broad interior plate for 

 supporting the eyeball from beneath. The horizontal limb of the 

 pra^opercidum is much shorter than the vertical ; both are minutely 

 serrated ; the angle rounded ; there are small openings from the 

 muciferous channel of the bone. The operculum is Ig as high as 

 wide, (quadrangular, with the upper side horizontal, and the posterior 

 slightly emarginatc ; it is provided at its inner sui-face with a bony 

 oblique ridge, terminating in a fice j)romiucnt spine. The sub-
