ANlMxA-LS which come from foreign countries, and can* 

 not be brouglit to England alive, mud be kept in fpirits to 

 preferve them from putrefaclibn, which makes them lefs fitted 

 for anatomical examination ; for the fpirits, which preferve 

 them, produce a change in many of their properties, and altec 

 the natural colours, and texture of the parts, fo that often 

 the ftrudure alone of the animal can be afcertained ; and where 

 this is not naturally diftinft, it becomes frequently intirely ob* 

 fcured, and the texture of the finer parts is wholly dethoyed, 

 requiring a very extenfive knowledge of fuch parts in animals 

 at large, to affifr us in bringing them to light : this happens to 

 be the cafe with the animal whofe diileflion is tlie fubjecl of 

 this Poftfcrlpti 



The animal may be faid to confifc of a flefliy covering, a 

 ftomach and inteftinal canal, and the two cones with their ten- 

 tacula and moveable fliell, which lafl may be confidered as ap- 

 pendages. 



The, body of the animal is flattened, and terminates in t\v6 

 edees, which are interfcfted bv rug.^. the fafciculi of tranfverfe 

 mufcular fibres which run acrois the back being continued 

 over them. Upon each of theie edges is placed a row of fine 

 hairs, which project to lome diifance from the Ikin. 



The flefhy covering confifts principally of mufcular fibres: 



thofe upon the back are placed tranlverfely, to contract the body
