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. Otherwise
