  • Cylichna jeffreysi Weinkauff, 1866




  • Atys. God of the Phrygians, companion of Cybele.
  • Jeffreysi. In honor to John Gwyn Jeffreys, (1809-1885), solicitor from Swansea, who got interested in conchology already when young. By conchology Jeffreys meant not only shell collecting, but the total science about molluscs. He began to organize dredging expeditions, visiting the Shetlands, W. Scotland, Channel Islands, Norway etc. and accompanied by chosen specialists. He took part in some longer expeditions to W. Greenland and the Bay of Biscay and visited collecting colleagues in foreign countries. He could not come to terms with Darwinism, because, according to his view, it implied that no borders between species were to be found. “British Conchology” in 5 volumes 1862-69 is his main work. His very extensive shell collection was purchased for the Smithsonian Institution 1883 by W.H. Dall.
