Some personal details:
I first joined the Conchological Society of Great Britain & Ireland in 1965. I am a Life Member and a Past President of the Society.
I have been the recorder for mollusca for the Yorkshire Conchological Society and the Yorkshire Naturalists' Union for over 25 years.
Since retiring from my post as Senior Curator Natural Sciences at the Leeds City Museum I have become involved with the International Council of Museums Natural History Committee as co-chair of the Working Group on the Art of Taxidermy and its Cultural Heritage Importance, as well as on their Ethics Committee. Within Yorkshire, I also chair the Yorkshire Naturalists' Union's Natural Sciences Committee and I am on the executive of the Yorkshire and Humberside Biodiversity Forum.
Recording:
The Conchological Society's recording scheme is about to be upgraded with all future records being entered into a national database. Most of the old records will also be upgraded into the database in due course. This will allow the information gathered to be accessed via the NBN Gateway. The computerisation of records is essential if we are to meet our obligations to public dissemination under the terms of the Charities Act. All contributors to the recording scheme will therefore be requested to allow their records to be made available to the wider public domain.
The new database will make it possible to produce maps to a much higher standard: 1-kilometre square, rather than the present 10-kilometre square maps that we are used to. This means that all recorders should try to ensure that records are submitted on a 1-kilometre square basis or less. Spot records will be required for specific species wherever possible. Below can be found a list of the non-marine BAP priority species, for which specific 6-figure or higher grids are requested. Some recorders may be unwilling to allow such specific data to be made available to others in which case these records can be marked as confidential and the specific data only released by permission of the individual recorder. (No specific details more accurate than 1-kilometre square will be placed directly on the NBN Gateway). A GPS reading is perhaps the most accurate method of recording down to this level of detail.
A number of further species have also been identified for which we need far more accurate data, (See list of additional species) , if we are to really understand their distribution and habitat requirements. These species are not under threat at the present time but if they need protection in the future, then a fuller picture of their distribution and habitat requirements may help us to make the correct decisions.
It is important to identify the habitat type, or describe it as accurately as possible, in each of these cases. Individual 'pink' cards may be acquired from the National Recorder or downloaded from this website for forwarding on to the Recorder.

Checklist
New Vice-county Recorders
Once I am able to establish the status of the VC recording system and bring it up to date, I propose to place all the VC records on this Website in Excel format so that all regional recorders can check these and update the records further. [Vice-county datasets are available by clicking here]. Some VC records have not been re-found for many years and some have never been re-found. Perhaps these could be identified and highlighted as being in need of checking?
Whenever possible, specimens should be collected and submitted for checking either to the National Recorder, or to one of the specialists listed, or to one of the regional recorders, and then forwarded to the National Recorder for inclusion in the Leeds City Museum reference collection, or placed in the collection of an accredited museum with molluscan holdings, and the details forwarded to the National Recorder.
Difficult Groups
In the main, the more difficult groups of species have been omitted from the list of species for which we require more accurate distribution records. This is due to the difficulty some members have in accurately identifying these. If in doubt, it is better, if possible, to collect a small number of adults and get them correctly identified rather than, as some do, ignore them or record them as aggregates.
The following people have agreed to look at specific aggregates. Please always e-mail them first before forwarding any material. (See notes on sending material through the post).
Stagnicola species: Ron Carr; e-mail: RONCARR200@aol.com
Pisidium species: Martin Willing; e-mail: martinwilling@godalming.ac.uk
Ian Killeen; e-mail: Ian@Malacserv.demon.co.uk
I am looking for volunteers who are willing and able to take on one or more of the difficult groups. If you are willing, please contact me at the above address or e-mail me at AdrianXNorris@aol.com'
Posting material for checking.
PLEASE NOTE - It is an offence to send live material by post, all material should be preserved prior to posting. The Conchological Society of Great Britain & Ireland does not accept responsibility if an offence is committed.
- Please make contact prior to sending any material to ensure that it can be received without any undue delay.
- Due to the high cost of postage, material will not be automatically returned unless the sender so requests. All non-returned specimens will be kept and placed into the Leeds City Museum's reference collection for future study.
- The recorder may ask for some material to be sent to alternative referees, in which case if the specimens are to be returned to the sender, please try to ensure that the cost of return postage is also forwarded to the referee.
