SECT. I. 



ITHERTO I have treated of fuch Sea-animals, caught 

 about the coafts of Norway, as are properly called Fifri ; 

 thefe have bones, or cartilaginous fubftance, and blood in them. 

 I now come to certain kinds, which are very different, and by 

 Ariftotle, Lib. i. Hift. c. iv. and Lib. iv. cap i. are divided into Difference 

 four kinds of Animalia exfanguia ; namely, the Soft kind, the and diviflon ' 

 Cruftaceous, the Teftaceous, and the Infects. Pliny makes but 

 three claffes of them, when he fays, Lib. ix. c. 2.8, " Pifcium 

 quidam fanguine carent, de quibus dicemus. Sunt autem tria 

 genera. Imprimis quse mollia appellantur, dein contecla cruftis 

 tenuibus, poftremo teftis conclufa duris." I fhall adopt this laft 

 method of claffing thefe kinds, only inverting the order with 

 relpecl: to their form and ufe. 



Firft, therefore, I fhall fpeak of the teftaceous kind, or thofe 

 that are confined in hard fhells, in which they live as it were in a 

 houfe ; fuch are Oyfters, Mufcles and Cockles. I mail after thefe 

 treat of the cruftaceous kind, that is, thofe which are furrounded 

 with a thin fhell, that is fhaped like, and juftly adapted to, their 

 bodies : of this fort are the Lobfter, the Craw-fifn, the Crab, 

 the Shrimp, and the Sea Hedge-hog. In the third place I fhall 

 defcribe the naked, or foft and defencelefs fort : fuch are the Scuttle- 

 fifh, various kinds of Star-fifh, and other curious fpecies, to be 

 nam'd in their order. If thefe kinds were very numerous, I fhould 

 treat of them alphabetically, as I have done in the preceding 

 chapters, in defcribing other fpecies : but as the difference in thefe 

 is much more perceptible, and the bounds I have prefcribed
