BIBLIOGRAPHY. 



Annals and Mag-, of Nat, Hist.— In the January number of the 

 "Ann. and -Mag. of Nat. Hist." Mr. Cockerell descrijjed a specimen 

 of Ibycus fissideiis Heyn {=sikkimensis G. Aust.), from a specimen 

 in the British Museum, entered in the accession book as Pai-tiiacella 

 oUvieri "purchased at Stevens." On comparing this description 

 with that of Il'ycus gracilis (Gray, 1855), Mr. Cockerell is of opinion 

 that -it is synonymous. The synonymy will therefore r^ad as under: — 



Ihyciis gracilis (Gray 1855), 

 = I. fissidens {Wtyn. 1862), 

 = /. sikkiineusis (G. Austen). 



British Naturalist. — Mr. Gain's observations on Molluscan Captives 

 are very interesting, and show a careful and painstaking piece of work. 



An interesting paper is communicated by Mr. Brockton Tomlin 

 respecting the decollation in Clausilia, ike. " Any conchologist," he 

 writes, "scrutinising an old wall in ordinary dry weather, must have 

 noticed how conveniently for his purposes many of the Clausilias 

 project from their coverts, the length of their shell rendering seclusion 

 impossible. This results in the tip of the shell getting bleached 

 (a constant phenomenon), and continued exposure would further 

 tend to disintegration of the affected whorls, and finally to their 

 disappearance ; the animal taking part in the last stage, when his 

 top storey had become dismantled and uninhabitable." Other 

 species are mentioned, particulars of which will be found on reference. 



Naturalist. — The V.N.U. report for Hayburn Wyke gives a total of 

 28 species ; that for the Wolds, 33 species ; and for Edlington and 

 Wadworth Woods, 22 species. 



Science Gossip. — Mr. Downes records and figures a specimen of 

 Clatisilia riigosa having two mouths: "Both were sinistral, and of 

 equal size, one forming the aperture of protrusion, and the other not 

 communicating with the interior, but fully formed in every particular." 



NOTES AND QUERIES. 



The Conchological Society's Census. 



— When are we to liave a new Census of 

 the British Land and Freshwater Shells? 

 This query I have often heard repeated by 

 my friends who are interested in eonchology. 

 I think (and not alone) that anotlier is 

 hadly required for two or three reasons. 

 Allowinii; that the Census at the end of 

 Mr. J. W. Wilhams' is. Manual of Land 

 and l''reshwatcr Shells is tlie hist one, there 

 are numerous alterations to be made in it. 

 As conchology is so very rapidly becoming 

 popular, the census ought to be kept up 



to date. During the past few months I 

 liave foimd the following which are not 

 recorded in the Census for C'ounty No. 6, 

 North Somerset : — 



Li max niaxintiis. — Common at liratton St. 

 Maur and the immediate district. 



Ifdi.x ///.<■(•(/. — FAtremely plentiful in a wood 



at Crawlands, near Ihatton St. Maur ; 



also common in liedgebanks at Mihon 



Clevedon. 

 Helix aciihata. — Faidy plentiful at Holbrook, 



Bratton St. Maur.
