des Poissonti, v. 606, of a supposed species of Sal- 

 mon found by "■ le citoyen Noel" in Loch Lomond, 

 which from its resemblance to a herrino- he deno- 

 minated Corcgone chipeoide. In the prosecution of 

 liife ichthyological researches, Dr. Parnell again found 

 the same fish, in abundance, in the same locality, 

 and has given a full account of it in the Annals of

 particulars. It occasionally grows to the length of 

 sixteen inches. Its food, from an examination of 

 the contents of the stomach, appears to consist of 

 entomostraca, the larvce of insects, beetles, and 

 small worms. It is very plentiful in Loch Lomond, 

 where it is known by the name of Poican or Fresh- 

 tcaler Herring^ and caught from March till Sep- 

 tember with large drag nets. It has occasionally 

 been taken v>ith a small artificial fly, but has never 

 been knoAvn to touch a minnow or bait of any 

 kind. Large shoals may be observed early in the

 rippling the water with their fins in their progress.

 are in best condition for the table in the months of 

 August and September, and are so much esteemed 

 as a well-flavoured and wholesome food, that most 

 of them are consumed by the inhabitants in the 

 neighbourhood of the Loch, and they are scarcely 

 ever carried to a distance. They shed theu' spawn 

 in October, November, and December, and are out 

 of condition till March. Dr. Paniell has observed
