SCYLLITJM. 



Generic Characters. The snout depressed, short, and blunt; nostrils

 covering of their skin rendered them troublesome to handle.

 canicula, No. 112, La Roussette tigree, the 

 Bounce of Bloch, has ocellated spots, and

 the Squalus stellar is of Authors. 



This species and the Rough. Hound, next to be mentioned, 

 are classed as ground Sharks, because their usual station is 

 near the bottom, where they seek their prey, mostly in rough 

 and rocky ground. Such of them as wander on more open 

 ground are of a lighter colour, in conformity with a law of 

 nature in fishes, by which they assume an intensity of tint 

 corresponding with the ground which they frequent. Their 

 food for the most part consists of crustaceous animals, as
