MR. COUCH appears to be the only naturalist who has 

 noticed the appearance of Mugil chelo on the British coast. 

 A decided difference observed in the habits of this Grey 

 Mullet compared with those of M. capita led to an ex-

 and the mouths of rivers in the winter months in large 

 numbers, all of which are just of one size. I have heard 

 of so many as two tons being taken at one time : but the 

 fish which I shall here describe was taken with about four 

 hundred others as they were left in a pool of our river,
