 CRUSTACEANS probably intended C.fuscata, Jurine, 'one of the most abundant British species.' ' Of the Copepoda the species recorded are entered as follows : Cyclopidx, comprising Cyclops quadricornis, very common ; ^ C. signatus, Koch, from Ore, including St. Helens and Coghurst ; C. strennus, Fischer, from Bopeep, the flat marshy ground known as the Salts, extending from Bopeep station to Bulverhythe ; C. gigas, Claus, com- mon ; C. aquoreus, Fischer, from Bexhill ; Calanidae, represented by Temora longicornis, Miiller, from Bopeep ; Harpacticidx, comprising Tachidius brevicornis, Miiller, from Bopeep ; Canthocamptus minutus, MuUer, common ; C ? pa/ustris, Brady, from Bopeep ; and Thalestris longimana, Claus, from Ecclesbourne.' The indefinite Cyclops quadri- cornis may be reckoned as a synonym of C. signatus. C. gigas is now considered to be a synonym of C. viridis (Jurine). Of the parasitic Copepoda the Hastings Natural History records in the Caligidas Caligus diaphanus, Nordmann ; in the Chondracanthidas Lenicntoma lophii, John- ston ; in the Lern^ids Lernceenicus spratta, Baird ; * and Adam White notes that the British Museum possesses Cecrops latreillii. Leach, of the family Cecropidas, from ' Selsey Bill, near Bognor, Sussex : presented by G. Newport, Esq.' ' This well known parasite of the sunfish, Orthagoriscus ?nola, is placed by Bassett-Smith in the Caligidae, under the heading Division II. Pandarinas. The same author displaces Baird's Lernentoma lophii in favour of the name Chondracantbus lophii given it earlier by Johnston, and follows Olsson and Richiardi in referring Lerneonema spratta to an older genus founded by Lesueur,* so that its proper title will be hernaenicus spratta (Sowerby). This slender species attaches itself, as might be guessed, to the sprat, while the preceding one is parasitic on Lophius piscatorius, known in English by titles of varying elegance, as the angler, the fishing frog, and the sea devil. The Thyrostraca, Cirripedia, or barnacles, are represented in Sussex, according to the record so often quoted, by Balanus balanoides (Linn.), very common, and B. porcatus, da Costa, these being in the sessile family Balanidas, while the pedunculate Lepadidae afford Lepas anatifera, Linn., L.fascicularis, Ellis and Solander, and Scalpellum vulgare. Leach, somewhat rare.' To the names of the species I have added the names of the authors to whom they are by the courtesy of science attributed, and although a simple catalogue gives us no means of judging whether the species themselves have been rightly determined, there is no real room for doubting that all the barnacles named in this particular list are to be found on the coast of Sussex. It should be mentioned in conclusion that the results of Mr. Guermonprez' careful and energetic researches were not at my disposal till this chapter in its earlier form was already in print.
