On Ceratotrema furcolabiata n.g. et n.sp. and Hemipera sharpei n.sp., Two New Digenetic Trematodes of British Marine Fishes

Material and habitat. Various Entozoa have been recorded from time to time occurring in the body cavity of their hosts, but very few records have been made of trematodes living in the coelom of fishes. Looss (1902) gives an account of Probolitrema richiardi (Lopez) occurring in the coelom of Mustelus vulgaris and Acanthias vulgaris, and this is the only form occurring in British marine fishes to which reference can be found in the literature (Nicoll, 1915).
