discovered by Mons. Noel, and described as a distinct species by 

 Lacepede in his " History of Fishes," under the name of Coregone 

 Cliipeoide. Dr Parnell has subsequently given a full account of it 

 in the "Annals of Natural History," Vol. I., an account which has 

 since been transcribed into the works of Mr Yarrell, Dr Hamilton, 

 and others. 



The powan is very common in Loch Lomond, and excites atten- 

 tion by its habit of approaching the shore towards nightfall, the 

 shoal making a commotion in the water with their fins. On these 

 occasions great quantities are taken with draught nets. Although 

 Dr Parnell states that the powan will not touch a bait, Mr 

 M'Niven has occasionally caught it with a common worm when 

 fishing for perch. One of the most curious facts connected with 

 this species is that of its being found in Loch Lomond and 

 no where else. 



Mr Alexander M'Kinlay laid on the table a valuable series of 

 rare Breadalbane mosses, and others, from Ben Nevis, the specific 

 differences of which he carefully described. Many of these speci- 

 mens possessed considerable interest.
