BIBLIOGRAPHY. 



Annals and Mag, of Nat. Hist.— Mr. T. D. A. Cockerell continues 

 his valuable notes on the Slugs in the British Museum. 



Mr. Edgar A. Smith records a series of Shells received from 

 Mr. John Brazier, of Sydney. 



Mr. Henry A. Pilsbry, writing on the genus I'eheiiophorus, points 

 out that if the present generic name has to be altered (as it has 

 been by Cockerell (Ann. and Mag. of Nat. Hist., p. 381, 1891) 

 to Li/iiacella, Blainville) it must be to r/iiloiiiycus Rafinesque, which 

 has been adopted by continental authorities, it having priority over 

 Mei^hiviatium, Hasselt. In the author's opinion, Eumelus, Rafinesque, 

 and Limacella, Blainville, are not at all applicable. 



Canon Norman contributes a most interesting article upon the 

 occurrence of Lepton squainosunt, Montagu, at Salcombe, Devon- 

 shire, where he found it in 1875. It was previously recorded by 

 Alder from this locality, and has also been found at Exmouth 

 by Clark. It was found in the burrows of Gehia stella/a, which 

 were lined with a slimy deposit, upon which possibly the Lepton 

 may feed ? 



British Naturalist.— Mr. Cockerell (Bibliography) very timely calls 

 attention to the fact that in the " Proceedings' of the Conchological 

 Society of Great Britain and Ireland," varieties of molluscs not 

 hitherto recognised in Britain are occasionally mentioned, but no 

 descriptions are given. He also points out two important changes 

 in the nomenclature, the first being that oi Avion minimus, Sim- 

 roth, lately described by Dr. Scharff as a British slug which is 

 identical with A. iiitevmedius. Norm., by which name it must of 

 course be known. The second is that of Avion bouvguignati, 

 Mabille, named in 1868; this is synonymous with the Avion cir- 

 eumseviptus, Johnston, described in 1828, and consequently claims 

 priority. A paper by the Rev. J. W. Horsley, M.A., is well 

 worth reading. 



In the Bibliography for February, Mr. Cockerell gives a very 

 useful review of the Land Mollusca mentioned in Westerlund's 

 great work {Fauna dev in dev /'aladveiischen Region, lehenden 

 Binnenconchylicn'). The Freshwater genera are similarly reviewed 

 in the March number. The system adopted by continental 

 authorities in regarding many of the forms distinct species which 

 we in this country only look upon as varieties, is one which is 

 both unscientific and mischievous, and we are pleased to know 

 that this is disapproved of by Mr. Cockerell. 



Journal of Conchology. — Mr. Taylor concludes his interesting 

 paper dealing with the variation of Z. pevegva. Adopting as the 

 type that considered by Jeffreys as typical, the various varieties 

 in the author's collection are dealt with under three sections, 

 viz. — "a. Spire short and aperture exceeding three-fourths of the 

 total length of the shell ; B. Spire produced, aperture not exceed- 

 ing three-fourths of the total length of the shell ; c. Modifications 

 other than those of form or outline, and which exist only in com- 

 bination with form variation." The paper enumerates twenty-nine 

 variations, and endeavours to some extent to reduce the excessive 

 number of some of the more specialised forms. 



Science Gossip. — Messrs. Jenkins and Grocock contribute a most 

 complete and interesting account of the Mollusca inhabiting the 

 marshes of the Thames Estuary. 



Zoologist. — All conchologists will be i)leased to hear of a new 

 locality for G. niaculosus, which Mr. Scully records from Co. Kerry, 

 some twenty miles from Caragh Lake, the original locality. 



* i^ We hope in futuve numhcvs to make this department much more complete, and to incorporate the titles of all 

 avticles, &^c., relating to Conchology from all the principal English and Foveign Magazines ; to this end we ask the 

 heavty co-operation of our readers, and especially that of the Secretaries of Scientific Societies for copies of Transactions 

 containing Conchological articles or reports.
