456 PILCHARD HERRING. Class IV. 



The body of the pilchard is less compressed 

 than that of the herring, being thicker and 

 rounder ; the nose is shorter in proportion, and 

 turns up ; the under jaw is shorter; the back is 

 more elevated ; the belly less sharp ; the dorsal 

 fin of the pilchard is placed exactly in the centre 

 of gravity, so that when taken up by it, the 

 body preserves an equilibrium, whereas that of 

 the herring dips at the head ; the dorsal fin of 

 the pilchard we examined, being placed only 

 three inches eight tenths from the tip of the 

 nose ; that of the herring four inches one tenth ; 

 the scales of the pilchard adhere very closely, 

 whereas those of the herring very easily drop 

 off. 



The pilchard is in general less than the her- 

 ring; the specimen we describe being a very 

 large one ; it is also fatter, or more full of oil.
