Bosminae have been taken by me in Darden and Svveethope 



Lakes, Northumberland ; also at Wynyard and Hardwiek 



Hall, Sedgefield, and moat at Raby Castle ; and I believe all 



of them to have been this species, but as it is more than forty 



years ago when they were found, and I merely have records 



and not specimens, it is possible that those from one or more 



of the Northumberland localities may belong to the following 



species (A. M. N.) N.D. 



Bosmina obtusirostris G. O. Sars. 



1867. Bosmina longispina, Brady and Norman, I.e., p. 358,
