Species Checklist for the British Isles.

    The existing species list for the British Isles as published in Scourfield & Harding, 1966 and on the old RA31 record card from the BRC, has been updated by members of this group and is available to download in the form of the 3 files detailed below. The list now includes the species codes from the Biological Records Centre as used on the new record card RA32, which can be downloaded from http:/

This is the basic species list in pdf format
The same list as an Excel spreadsheet, useful to make your own record sheet
These notes describe the amendments, additions and deletions, complete with references and acknowledgements.

An update list for the key by Amoros .

    This document has been produced by one of our members, Dave Bentley. It allows users to annotate a copy of Amoros in line with the new species checklist for Britain & Ireland. You can easily update the species names and note the species in Amoros that do not occur in Britain & Ireland. Dave also shows where in Amoros most of the few unlisted British species would key out. There will then remain only two species, both listed as 'Species Inquirenda' in the British checklist, which are not covered in your anotated copy of Amoros. These are Alona karelica & Bosmina longispina. If any other members can add pointers to the places in Amoros where these will key out and how to distinguish them we would welcome suggestions.
    This makes the Claude Amoros key, used in conjunction with Scourfield & Harding, much more user friendly although the usual species which are difficult to separate remain, such as the D. longispina / hyalina group.

Download the D.G.Frey collection of Cladoceran Literature, listed in a spreadsheet.

    The following is extracted from an article in Cladocera News 8 submitted by Rodney V. Harmsworth ....
"David Frey obtained a large number of papers while on sabbatical leave at the Museum of Natural History in London in 1963. The papers formed the basis of his literature collection.
I was a graduate student from 1963 to 1966, and was assigned the task of cataloguing Frey’s cladoceran literature. Subsequent to 1966 a secretary sent cards that were added to the file. Amy Collie assisted by entering the data into the file. This file represents most of the world’s cladoceran literature from O. F. Muller’s paper in 1769 to D. G. Frey’s paper in 1975. It consists of 1500 references. No attempt has been made to expand the file since that time.
David Frey’s son Karl informed me that his collection of literature, slides, specimens and collections were sent to the Smithsonian
