Jeffreys’ Collection: An Unrivalled Collection
Jeffreys amassed a large and comprehensive shell collection. It was described as being unrivalled for British marine molluscs at the time of his death. The collection contained representatives of over 700 mollusc species, averaging 50 specimens per species!
It held examples of every new species described by Jeffreys in his work British Conchology and in his subsequent papers. It also contained the original collections of other early British naturalists such as Turton, Alder and Clark, whose collections he had acquired.
