More than 1,150 fluid-preserved British spiders with data make up the collection. As yet the collection has not been fully analysed and we are unsure how many of the 600 or so British species are present.
The main collectors represented are I Blair-Brown, M Charig and S J Moore.
A relatively small collection of mostly spirit preserved British marine, freshwater and terrestrial invertebrates. Crustaceans (crabs and shrimps), echinoderms (sea urchins and& starfish), myriapods (centipedes and millipedes), coelenterates (sea anemonies, corals, hydroids and jellyfish), tunicates (sea squirts) and annelids (worms) are all represented. Most of the material has been collected by museum staff. The R Wells collection of marine invertebrates is the only named collection.
