256 PISHES. 



their habits are greatly like those of worms, which they otherwise 



so strongly resemble.* 



One of them is found in France, the Petrom branchialis, L. ; 

 Lamprillion, Civelle, &c. (the Common Pride.) From six to 

 eight inches long, and the size of a large quill ; it has been 

 accused of sucking the branchiae of fishes, possibly from having 

 confounded it with the Petrom planeri. It is used as bait.f«)

N.B. The Petrom. rouge, Lacep., II, i, 2, belongs to this genus, and perhaps does 

 not differ materially from the common species quoted. 



0^=" (a) Some pains having been taken within the last few years to determine the 

 species of the class of fishes which frequent the coast of Cornwall, we feel that to 

 supply the results of this investigation, would be by no means useless or uninter- 

 esting. Great praise is due to Mr. Cornish of Polpero, for his long continued exer- 

 tions in this department. In this gentleman's description, he employs the classifi- 

 cation of Linnseus. We shall present the species furnished by Mr. Cornish, in the 

 manner in which he has arranged them, and also according to the classification of 

 Cuvier. 



The fishes were divided by Linnaeus into four orders, the Apodes, Jusrulares, Thora- 

 cici, and Abdominales. The Cornish fishes are distributed by Mr. Covnish according 

 to this classification. 



ORDER I.— Apodes. 



Fishes with a smooth slippery skin, generally naked, or covered in some species 

 only with small soft scales which are distant from each other. Body slender, teeth 

 in the jaws, live mostly in the sea, but some are found in rivers and ponds. 



Mv.rd.na Anguilla, the eel, found in rivers near the coast. The eel as has recently 

 been determined is oviparous, the only reason which previously led to the notion of 

 its being viviparous, was that a couple of parasitical worms were usually found in its 

 interior, which were mistaken for ,the offspring. This species belongs to the fourth 

 order of Malacopterygians, the Apodal Malacopterygians of Cuvier, which see. 



Mur. Conger, the Conger Eel, found in rocky ground on the Cornish coast. 



Xiphias Gladius, the Sword Fish, very frequent. 



Ammodytes Tohianus. Mr. Cornish states that this is the Launce, but the Launce 

 evidently is the Leptocepholus. 



ORDER II.— Jugulares. 



Fishes with ventral fins, placed more forward than the pectoral fins, or under the 

 throat. These fishes belong to the order x\canthopterygians of Cuvier. 



Caltionymus Lyra, the Dragon fish, or gemmeous Dragonet. Rare. 



('. Dracunculus, the Skulpin. 



Trachinvs Draco, the great Weever. The puncture of the dorsal fin of this fish i« 

 poisonous. 



Gadus Oglejimts, the Haddock. 



G. Morhua, the Cod-fish. 



G. Luscus, the Bib. 



G. Minutus, the Poor. 



G. Molva, the Ling. 



G. Mustella, the five bearded Cod, or more commonly called Rock Ling. 



G. Merlangus, the Whiting. 



G. Pollachius, the Pollack. 



G. Carbonarius, the rauning l'ollach, or Conl fish. Raitning is a Cor.iish word for 

 ravering, this fish being exceedingly voracious. 



G. Merlucius, the Hake ; this fish appears with Pilchards. 



Blennhts Phohs, the Shanny.
