PROCEEDINGS OF THE CONCHOLOGICAL SOCIETY. 315 



Wiih regard to the number oi species (not records merely) registered for 

 the various counties and vice-counties, the average is now 41 species per 

 county as against 36 at the date of the previous report. The average for the 

 72 counties of England and Wales has been raised from 56 to 58, for the 41 

 Scottish counties from 21 to 31, a notable increase, and for the 36 Irish 

 counties from 14 to nearly 20. It will thus be seen that a great advance 

 has been, made during the year in the authentication of Scottish 

 Mollusca. This has been in the main due to the fact that your Recorder 

 presented a paper to the Royal Physical Society of Edinburgh dealing with 

 the comital range of Scottish Mollusca, which will shortly be printed in their 

 Proceedings, and that to render it more complete numerous Scottish naturalists 

 have co-operated by sending material for authentication. More particularly 

 is credit due to Mr. William Evans, F.R.S.E., the able Secretary of the 

 Royal Physical Society, for the energy and success with which he has 

 laboured both personally and by correspondence to provide material for 

 accelerating the completion of our knowledge of the range of Land and Fresh 

 Water Mollusca in Scotland. He has thus done for the eastern side of 

 Scotland what our old friends Mr. A. Somerville and Rev. J. E. Somerville 

 did for the western and northern districts a year or two ago. The Society is 

 also indebted to Mr. Alex. Shaw for much assistance in this respect, while to 

 the Rev. Dr. Gordon, of Elgin, the Society's thanks are due for the privilege 

 of inspecting the whole collection of Land and Fresh Water Mollusca be- 

 longing to the Elgin Museum, which was specially sent to Leeds for 

 examination. 



For English records the Society has been indebted to numerous con- 

 chologists, particularly to Mr. E. R. Sykes for the inspection of a very full 

 set of Dorsetshire Shells, and to Rev. W. L. \V. Eyre for shells from South 

 Wiltshire and North Hampshire. 



For Ireland, numerous shells from various counties of Ulster and Con- 

 naught have been submitted by Mr. J. G. Milne, from Mayo and Sligo by 

 Miss Amy Warren, and from Louth by Miss vSidney Smith. 



There is one respect, however, in which no progress has been made, and 

 the four counties (Queen's, Carlow, Longford and Galway East) from which 

 no records had been made at the date of the last report remain 1)1 ank or 

 virgin counties still. In addition to these four there are 17 from which the 

 total number of authenticated records still falls short of ten each, and to 

 which it is therefore hoped that Members will pay special and speedy 

 attention. These are the Welsh county of Radnor, the seven Scottish 

 counties of Dumfries, Aberdeen North, Westerness, Ebudes South, Ebudes 

 North, Orkney, and Shetland, and the nine Irish counties of Donegal, Cavan, 

 Kildare, Wicklow, Kilkenny, Roscommon, Clare, Tipperary North, and 

 Cork North. 



In conclusion the Recorder has to thank the Members and others who 

 have so heartily co-operated in the work of authentication for so many years.
