 portions of this cone rubbed flat and formed into regular discs of uniform size.

 curiously eroded Planorbis cornens, H. cantiana var. albida, and H. virgata var. 

 macnlata from Scarborough ; H. arbustomm var. fnsra from Durham ; white 

 varieties of ZT. hispida, Clansilia laviinata, CI. biplicata &.n6. Janiinia cylindracea ;

As a special exhibit, very fine series of Cylindrellida;, including about one 

 hundred of the known species, were shewn by Messrs. Ed. Collier, R. Standen, 

 J. W. Baldwin, and Mrs. Gill. The "Layard," " Darbishire," and general 

 collections in the Manchester Museum were also exhibited. Mr. Collier gave an 

 interesting resume of the life-history and geographical distribution of the group — • 

 which according to the latest classification must now be known under the name 

 Urocoptidie. He drew attention to the eccentric form, and beauty of sculpture, 

 which characterise many of these curious shells. 



Pisidium personatum Malm at Mortehoe — a correction.— Mr. B. B. 



Woodward writes me as follows : " Fisidiitm personatitJ/i from Church Close, 

 Mortehoe (v. supra p. 23) proves — or at least the specimens received from Mrs. 

 Longstaff prove — on a recent and more thorough investigation to be P. nitiditm. 

 This is an addition to the Mortehoe list." — Ed.
