Austrocochlea
''Austrocochlea'' is a genus of medium-sized sea snails, marine gastropod molluscs in the family Trochidae, the top snails, also known as top shells. This genus was founded as a subgenus by Fisher in 1885 to include a small group of Australian species, included in the genus ''Monodonta''. They had previously been included in ''Trochocochlea'' Klein, 1753 ( = ''Osilinus'' Philippi, 1847), a section that was then restricted to the Mediterranean group. Distribution This marine species occurs off the Philippines and mainly off Australia. Species Species within the genus ''Austrocochlea'' include: * '' Austrocochlea brevis'' Parsons & Ward, 1994 * '' Austrocochlea constellata'' (Souverbie, 1863) * ''Austrocochlea constricta'' (Lamarck, 1822), the southern ribbed top snail * '' Austrocochlea diminuta'' (Hedley, 1912) * '' Austrocochlea piperina'' (Philippi, 1849) * ''Austrocochlea porcata'' ( A.
