See Travels, p.174 Adams visited the island, which is inhabited or at least used as a Haliotis-fishing station by Coreans, on the 28th of June, 1859. It is densely wooded, with a central peak 4,000 feet high. In the Travels, p. 178, a slug "with the mantle covering the whole of its back"(probably Philomycus) and a Zua (Coehlieopa) are mentioned.
