Whether Caloearis be a recent introduction or not, there is apparently no doubt as to its having now a right to be reckoned amongst the Crustacean fauna of the Forth. The number of Crustacea recorded in the present paper is scarcely so large as in that published last year, but there are included several species apparently undescribed, and others which are new or rare in the Scottish seas. The following are the more interesting of the species recorded: --Xanthocalanus (?) borealis, G. O. Sars. (?) Pfuenna zetlandica T. Scott (sp. n.) Scolecithrix (?) brevicornis, G. O. Sars. Platypsyttus minor, T. Scott (gen. et sp. n.). Nereicola concinna, T. Scott (sp. n.). Stenhdia confusa, T. Scott (sp. n.). Ameira tenuicornis, T. Scott (sp. n.). Ameira propinqua, T. Scott (sp. n.). Pseudomesochra longifurcata, T. Scott (gen. et sp. n.). Leptopontia curvieauda, T. Scott (gen. et sp. n.). Normanella attenuata, A. Scott. Fultonia hirsvta, T. Scott (gen. et sp. n.). MonstrUla longiremis, Giesbrecht. Tliaumaleus thompsoni, Giesbrecht. Pseudopsyllus dongatus, T. Scott (gen. et sp. n.). Aconttophorus ornatus (Brady and Kobertson). Cancei-illa lubulata, Daly ell. Salenskya tuberosa, Giard and Bonnier..' It will be observed from the above list that five new genera and ten new species are described in the present paper. There were a few other interesting organisms observed, such as Area pectunculoides and Cadulus subfusiformis (two species of Mollusca), but valves only of the first, and a recently dead specimen of the other, were obtained.
