GREY MULLET. 205 



good things ; viz. a Chicliesier lobster, a Selsey cockle, 

 an Arundel mullet, a Pullborough eel, an Amberley trout, 

 and a Rye herring. In reference to the Mullet, I may 

 notice, that during the summer of 1834, probably owing to 

 the warmth of it, the Grey Mullet migrated much farther 

 up the river than usual, and were caught above even where 

 the spring-tides flow, as high up as Amberg Castle, which 

 is by the river nearly ten miles above the town of Arundel, 

 and nearly twenty miles from the sea. 



The partiality exhibited by the Grey Mullet for fresh 

 water has led to actual experiment of the effect of con- 

 fining them to it entirely. Mr. Arnould put a number 

 of the fry of the Grey Mullet about the size of a finger 

 into his pond at Guernsey, which is of about three acres 

 area, and has been before referred to under the article Basse. 

 After a few years, Mullet of four pounds 1 weight were 

 caught, which proved to be fatter, deeper, and heavier for 

 their length, than others obtained from the sea. Of all the 

 various salt-water fishes introduced, the Grey Mullet appeared 

 to be the most improved. A slight change in the external 

 colour is said to be visible. 



The length of the head in this fish, compared with the 

 length of the body and tail, is as one to four : the depth of 

 the body is equal to the space from the anterior edge of the 

 orbit to the end of the operculum, and the body does not 

 decrease in size till the commencement of the anal fin : the 

 fleshy portion of the tail is equal to half the depth of the 

 body. 



The form of the mouth is different from that of most 

 other fishes. The lower jaw is divided in the middle by 

 an ascending angular point, which, when the mouth is closed, 

 passes within the upper jaw : the upper jaw, also, if viewed 

 from below, is angular ; each jaw is furnished with a single
