BIBLIOGRAPHY 



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



Monograph of the Land and Freshwater Mollusca of the British Isles, 



part 17, pp. 225-304, with 6 plates, by J no. W. Taylor (Taylor Bros., Leeds). 



We heartily welcome another part of Mr. Taylor's great Monograph, giving a 

 further instalment of the HelicidiT. Mr. Taylor is now "in the thick" of the species 

 which are still allotted to the old genus Helix, and which undoubtedly hold the rank 

 of prime favourites with most British collectors, whether it be on account of their 

 attractive appearance or their fascinating variability. It is not, therefore, sur- 

 prising to find that the eighty pages of the present part only contain the conclusion 

 of Helix poinatia, the complete monography of H. aspersa, and the beginning of 

 H. ne'iioralis. Of the six plates whicli accompany, four are the distribution cliarts 

 of Pnnctiim pygniceuvi, Pyramidnla rotundata, P. rupestris, and Helix pomatia. 

 The other two, also coloured, give us twelve beautiful figures of varieties and mon- 

 strosities of the last-named species, and are, we think, a most successful piece of 

 work. To the records of reversed H. poinatia we may add a Kentish specimen 

 received from a lady by the late Mr. Alfred Leicester, and with his wonted generosity 

 added to our collection. We think it may be certainly assumed that Dr. Lukis's 

 attempt to colonise this H,lix in Guernsey failed, as assiduous collecting there from 

 1883 onwards has failed to discover even a dead shell. Under A*", aspersa Mr. Taylor 

 reproduces some beautiful photographs of cavities exca\'ated by this species in the 

 limestone, and of its feeding tracks.
