SHAD. 105 



general habits seem to resemble those of the Her- 

 ring, and it appears in almost equal plenty about 

 several of the European coasts, particularly about 

 those of the southern parts of our own island, where 

 it is taken in vast quantities. The numbers, says 

 Mr. Pennant, from the attestation of Dr. Borlace, 

 that are taken at one shooting out of the nets is 

 amazingly great. On the fifth of October 1767 

 there were at one time included in St. Ives's bay 

 7000 hogsheads, each hogshead containing 35000 

 fish, in all 24000000. 



The Pilchard, according to Mr. Pennant, usually 

 appears in vast shoals off the Cornish coasts about 

 the middle of July, disappearing in the beginning 

 of winter, though a few return again after Christ- 

 mas : their winter retreat, the same author observes, 

 is supposed to be the same with that of the Herring.

THIS species resembles the Pilchard in general 

 appearance, but is of much larger size, much thinner 

 or flatter in"proportion, and is farther distinguished 

 by the scales on the lower part of the abdomen,
