The general character of the fauna was that which we have hitherto been in the habit of regarding as Northern. Several interesting things were met with—Nucula tumidula, Malm.; Eeda frig id a,Tov^eli,; Verticordia abyssicola, Jeffreys ; and Siphonodenta- lium quinquangulare, Forbes. Among the echino- derms a multitude of the large form of Echinus norve-. Fig. 8.—Gonoplax rliomboidcs, Fabbicivs. Young. Twice the natural size. (No. 3.) gicus, D. and K., which I am now inclined to regard, along with several of its allies, as a mere variety of E. flemingii, Ball ; and the fine asterid already mentioned, Brisinga coronata, G. O. Sars. Some interesting crustaceans, including Gonoplax rliom- boides, Fab. (Fig. 8), a well-known Mediterranean species, and a young specimen of Geryon tridens, Kroyer (Fig. 9), a rare Scandinavian form, and the only known North European brachyurous crustacean.
