BIBLIOGRAPHY, 



(limited to works received by the society's librarian). 



"Monograph of the Land and Freshwater MoUusca of the British Isles," 



by John W. Taylor (parts 13 and 14, pp. 281-312 and pp. 17-64). 



This double part completes the Appendix, and brings the second volume, which 

 comprises Testacellidce, Litnacida:, and Arienidce, to a conclusion. Two excellent 

 coloured plates illustrate the variation of Geomalacus and the various species of 

 Arion, the figures of the former being particularly good. 



This part also contains Hyalinia lucida, H. cellaria, H. helvetica, and H. 

 alliaria. Mr. Taylor gives adequate reasons for employing Blum's name helvetica 

 for the shell which Jeffreys erroneously caWeA glaber Stud., and very fully discusses 

 its affinities as shown by the radula.
