XXIII. — Miscellaneous Notices and Observations. 



Panopcea Norvegica. — Last autumn a fisherman brought to 

 me a full-grown living specimen of this mollusc, which he said 

 he had taken near Eyhope a little below low-water mark. He 

 had been collecting bait, and while so engaged noticed the ani- 

 mal in the water, and waded in for it. I never heard of its 

 occurrence in any other instance except in deep water, but have 

 no reason to doubt the truth of the account given me by the 

 fisherman. — George S. Brady, Sunderland, April 12th, 1870. 



Fresh-ivater Rhizopods. — In some gatherings made by the hand 

 dredge in Fardings-lake, near Marsden, I noticed numerous 

 specimens of Diffd^tgium, an organism which I do not remember 

 seeing elsewhere in this district, but which may probably only 

 need looking for to be found frequently. — Ibid.
