A wooden, two-masted paddle gun-vessel, built at Deptford Dockyard in 1844, the Porcupine was 141 feet long and had a displacement of 490 tons. This rather poor photograph, apparently the only one of the ship in existence, is reproduced by kind permission of the Hydrographcr to the Navy. parts of the collections were never worked up adequately. In particular, with the exception of the isopods. very few of the crustaceans were reported upon at all except in The Depths of the Sea. In the case of the decapods, Thomson mentioned three previously undescribed crab species. DorhyrKhus thomsom (as Doryrichiis. see Holthuis, 1962). Rochinia carpenteri (as Amalhia) and Cymonnmus (as ). Thomson made it clear that he had been furnished with these names by A. M. Norman to whom the study of the crustaceans had been entrusted. Norman had recognised these species as new. but neither before the appearance of Thomson's book, nor subsequently, did he publish descriptions of them. The Porcupine collections also included a fourth un- described crab species, Ebalia which was not mentioned by Thomson and first appeared in print as a nomen nudum in a preliminary account of the voyage of the Travailleur (Norman. 1880) and was subsequently figured in Milne-Edwards (1883) and described in Pocock (1889). In the ensuing confusion the names have been variously attributed to Norman, Thomson. Norman in Thomson. Milne-Edwards, and Norman in Milne-Edwards (see Appendix I). Phis paper attempts to explain how this confusion arose and to establish the correct authorship of the species concerned. In dealing with these questions I have inevitably become embroiled with the "Norman Collection", a large collection of crustaceans and many other invertebrate groups, which came to the British Museum (Natural History) around the turn of the century.
