Iceland to Mediterranean. On continental shelf, attached to various organic wreckage. Original taxon: Myrina simpsoni.

« In the month of June last an Aberdeen trawl-boat brought into that port the skull of a whale, which arrested the attention of Mr. James Simpson, an indefatigable collector of the Mollusca, who resides in that city. When he went on board to examine it he found the skull bare of flesh, but covered with an oily exudation caused by some days exposure to a very hot sun, and although it was almost unapproachable on account of the indescribable stench, he went close enough to observe a number of “small mussels” clinging to it, and secured some of them. He writes me that “there must have been thousands on the skull, but by far the largest number were baby shells. The adults were anchored by a byssus in the cavities, while the young swarmed over the smooth surfaces. They were very much decomposed, so I was glad to get rid of the animal matter as soon as possible.” » – J. T. Marshall: “On a british species of Myrina”, The Journal of malacology vol. VII, London 1900, via BHL.

« Mr. Simpson having submitted some of these “mussels” for my opinion, I at once saw they were unlike any species yet found in our seas, and that they corresponded very closely indeed to the Myrina of H. and A. Adams, a genus founded on a single Japanese species. I propose therefore to name this shell Miyrina simpsoni, after the discoverer. » – Ibid.

« Since my paper on the subject appeared in this journal, a piece of pitch pine, bored by Xylophaga and Teredo, was landed on the fish-quay of Aberdeen by a trawler, who said it came from the “Shetland fishing-grounds”, and in the deserted tubes were Aduda simpsoni attached by a byssus. […] At the time of writing another whale’s skull has been landed at Aberdeen by a local trawler, which was brought up “20 miles N.W. of Fair Isle” (between the Orkneys and Shetlands), to which two or three dozen A. simpsoni were attached. » – J. T. Marshall: “Note on Myrina simpsoni”, The Journal of malacology vol. VIII, London 1901, via BHL.
