lias usually more rays, one specimen having 10 branched 

 laye, three 9, and only one 8. 



"Dr. D. Embleton (Nat. Hist. Trans. Northumb. and 

 rurliam, v. 1877, p. 146) states that in 1872 he obtained 

 .several specimens of the Derwentwater Vendace, and presented 

 iheni to the Newcastle Museum, but on enquiry I find that 

 those have not been ])rescrved. j\lacpherson, in the ' Fauna of 

 l.j'.keland,' p. 517 (1892), gives an interesting account of this 

 species, from which I gathf r that Hutchinson, in the * History 

 of Cumberland ' {circa 1794), recorded the Vendace as 

 inhabiting Bassenthwaite Lake and tiiat in 18"i6 Davy wrote 

 that he had heard of one being taken with the fly and one 

 with a worm, but that in the last eight years a good many 

 had been taken in both lakes by net. They appear to be 

 scarce at the present day and are not netted. 



The honorary curator of tiie Keswick Museum, Mr. H. A. 

 Beadle, very kindly sent me the five specimens described 

 above, with permission to retain one for the British i\luseum 

 collection. These were found dead, floating on the water, 

 and Mr. Beadle tells me he has never known one to be caught 

 by an angler. It is hoped that more examples of this 

 interesting species may soon be added to the National 

 Collection.
