than those of pagrus, and consequently much more so 

 than those of chrysophris. There are frequently more than 

 two ranges, but those of the two external ranks are the 

 thickest. 



The pagelli live on fish and shell-fish, go in small troops, 

 approach the coasts towards spriug, and remain there until 

 winter. There are even some species which sojourn the whole 

 year on the coasts of the sea of Nice. 



The common pagellus (P. erythriitus, Cuv.) is very abun- 

 dant in the Mediterranean, and even enters the Atlantic, 

 where it advances pretty far towards the north. They are 

 numerous at Marseilles, Naples, Nice, Genoa, and Sicily. 

 Gronovius took one at Schevelingen, though the pagel must 

 be rare in so high a latitude, for it is not to be found in 

 Donovan or Pennant. We certainly find in the Danish Fauna 

 of Muller a spams erythrinus, but its characteristic phrase 

 and its citation from Olafsen are referrible to the sebastes of 

 the north. The article which he cites from Stroen appears 

 to indicate the sparus salpa. Other authors of Northern Fauna 

 make no mention of it. 



The pagel does not approach the shore except towards 

 spring. It is commonly found at the depth of fifty or sixty 

 fathoms, and Duhamel says that the female suffers her eggs 

 to escape at this great depth. According to M. Risso, this 

 fish is found during the whole year on the rocks of the coast 

 of Nice. 



The genus Dentex is so called after the ancient name of 

 one of the species. It consists of fishes of the family of the 

 spari, which have only conical teeth in both jaws, usually 

 on a single rank, with some of the anterior elongated into 

 large hooks. Like the other spari, they partake a good deal 

 of the character of the sciaenoides with simple dorsal, but are 

 easily distinguished by their preoperculum not being denticu- 

 lated, but having the edge entire. As their operculum is ter-
