Exhibits. 



By Mr. W. Moss : The series of Barbados Shells sent by Mr. L. B. Brown to 

 illustrate his paper. Mr. Moss also showed his own fine collection of Barbados 

 mollusca, which is very complete, and contains long series of varietal forms. 



By Mr. J. W. Baldwin : Helix horlensis of the form minor-coalita from Chatburn. 



By Mr. Cairns : Planorbis dilatatns discovered in the collection of the late Mr. 

 T. Rogers, and, judging from the label, evidently the original specimens taken by 

 him, in 1869, and sent to Gwyn Jeffreys for identification. These historic speci- 

 mens passed into Mr. Cairns' hands on the acquisition of Mr. Rogers' collection by 

 Mr. H. B. Preston. 



By Mr. J. W. Jackson : A series of land shells from the Darland Hills, Kent ; 

 abnormal dwarf forms of Mytilus edulis from the breakwater at Leasowe, Cheshire ; 

 Ccecilioides acicula and other species collected during the Miller's Dale Ramble on 

 August 9th ; an interesting series of young forms of Vivipams contediis ; Hya- 

 linia excavaia type and var. vitrina, from a new locality near the Roman Bridge, 

 Marple, Cheshire ; Limmxa buliinoides Lea, from Wibany, Montana — these speci- 

 mens were sent by Prof. W. H. Dall for comparison with the unknown Limncea 

 discovered last year in the Dukinfield Canal, and believed to be L. bulimoides, this, 

 however, proves not to be correct, and the Dukinfield specimens still remain 

 undetermined.
