The peritone^nn 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 arc If as long as the whole fish ; the air- 

 bladder is posteriorly divided into two large horns, situated between 

 the muscles of the tail and the haemal 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 with two low elongate protuberances, which chvergc 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 intennaxillaries is strong and 

 thick; their posterior processes equal in length the descending 

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

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

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

 The turbmal bone is very elongate and tubiform, the pifeorbital 

 rhombic, the suborbital arch narrow, with a broad intez-ior plate for 

 supporting the eyeball from beneath. The horizontal Unib of the 

 prajopercidum is much shorter than the vertical ; both are minutely 

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

 muciferous channel of the bone. The operculum is 1| as high as 

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

 slightly emarginate ; it is provided at its inner surface with a bony 

 oblique ridge, terminating in a free prominent Ri)ine. The sub- 



* The series of small scales on the back and on the belly are included in these
