' Porcupine ' Exp. 1870 : Atl. St. 24-28. Distribution. Mediterranean (Italian Expedition, 1881); 217 fms. Family IV. CALYPTR^EiDiE. C A L Y P T R ^ E A CHINENSIS, Linne. Patella chinensis, L. S. N. p. 1257. C. chinensis, B. C iii. p. 273, pl. vi. f. 6 ; v. p. 201, pl. Ix. f. 1, la. ' Porcupine ' Exp. 1870 : Atl. St. Vigo B., 16, Setubal B., off C. Sagres, Tangier B., Gibraltar B.; Med. Algesiras B., Cartagena B., Benzert Road, Rasel Amoush, Adventure Bank. Distribution. Dublin Bay, Milford Haven, southern coasts of England and Channel Isles, Brittany, S.W. France, throughout the Mediterranean and Adriatic, Black Sea (Clessin), Red Sea (Issel), off Morocco ('Travailleur' Exp. 1881), Madeira and Canaries; 0-130 fms., usually inhabiting shallow water. The Scotch localities, given on the authority of Laskey and Leach, are certainly unreliable. Fossil. Miocene?: Modena (Foresti). Pliocene: Coralline, Red, and Norwich Crags, Belgium, S. France, Italy, N.W. Germany' Switzerland, Vienna Basin, Transylvania, Hungary, Rhodes, and Cos. Post-tertiary : Leghorn (Castelli, f. Appelius). There are about a dozen more or less recognized synonyms, including C. sinensis. The monstrous variety which is moulded on Turritella terebra is very curious. CREPIDULA UNGUIFORMIS, Lamarck. C. unguiformis, Lam. An. s. Vert. vi. (2) p. 25 ; Sowerby, Gen. Crepidula, f. 6. 'Porcupine ' Exp. 1870 : Med. St. Adventure Bank. Distribution. G. Gascony (De Folin)!, Morocco, Mediterranean and Adriatic, G. St. Lawrence and eastern coasts of N. America • 0-40 fms. Fossil. Miocene: Vienna Basin, Switzerland, S.W. France. Pliocene : Belgium, S. France, Italy, Algeria. Post-tertiary : Pozzuoli (Philippi). This species also rejoices in, or rather laments, about a dozen synonyms. It is the Patella crepidula of Linne, C. fomicata of some authors (but, perhaps, not P. fomicata of Linne), and C. plana of Say. When the so-called C. fomicata is found adhering to the outside and C. plana to the inside of the same specimen of another American shell, they may easily be mistaken for distinct species. C. moulinsi of Michaud is a we'll marked variety, its principal character being dependent on coloration. The young have a short spire like that of Calyptraa chinensis. Crepidula spirata of Nardo is also the present species, and derives its peculiar shape and prominent spire from being affixed to Turritella terebra,\\ke Calyptraa chinensis. sv |
