BIOGEOGRAPHICAL RELATIONSHIPS OF THE MOLLUSCAN FAUNA OF THE ORMONDE SEAMOUNT (GORRINGE BANK, NORTHEAST ATLANTIC OCEAN)
Thirty-six taxa (28 Gastropoda and eight Bivalvia) were collected at Ormonde Seamount (Gorringe Bank). Trochidae and Rissoidae, both with three species, were the best represented families. Manzonia crispa (Watson, 1873), formerly thought to be restricted to Madeira, has its range extended to the nor...
