a few from other counties), and of Mr. T. W. Bell, who has 

 similarly illustrated the molluscan faunas of Northamptonshire 

 and Cambridgeshire. A full series of the shells of Western 

 Sussex has been shown on behalf of Mr. W. Jeffery, and another 

 series of the shells found round Bristol by Mr. J. W. Cundall. 

 The records of the two latter gentlemen form the basis of papers 

 written by them and published in the "Journal of Conchology." 



Of Yorkshire shells, 830 records of 95 species and varieties 

 have been authenticated — making a decided advance upon the 

 previous year's figures, when only 200 records of 63 species and 

 varieties were made. P'ourteen of the forms which were shown 

 from Yorkshire localities were this year exhibited for the first 

 time. This makes the total number of exhibits from Yorkshire 

 localities since the foundation of the Society amount to 2136; 

 the total number of forms — species and named varieties — being 

 145. For the remainder of the British Isles, we have had 

 altogether 534 records for 44 counties or divisions of counties. 

 Of these, 70 forms have been recorded for West Sussex, 59 for 

 Northamptonshire, 35 for the Bristol district, 23 for the Isle of 

 Man, and 19 for Cambridgeshire; while none of the others have 

 reached these figures, excepting, of course, the five divisions of 

 Yorkshire, the numbers of which are as follows: — 122 for Mid- 

 West Yorkshire, 94 for South-West Yorkshire, 67 for North-West 

 Yorkshire, 58 for South-East Yorkshire, and 43 for North-East 

 Yorkshire. 



The object for which the records are accumulated is the ulti- 

 mate preparation for publication of a series of county-lists of Mol- 

 lusca, which shall be of uniform and known value, serviceable for 

 the use of writers on the geographical range of mollusca, and the 

 merits of which shall be that every statement contained in them 

 shall have been vouched for by the actual exhibition of a specimen 

 to competent judges. It is thus hoped that a service to concholo- 

 gical science may be rendered, similar to that which has been 

 rendered to geographical botany by the medium of the admirable 

 system, stringently enforced, of the Botanical Record Club.
