Homalopoma emulum (Seguenza, 1876), a bathyal cold stenothermic gastropod in the Mediterranean Pleistocene
Homalopoma emulum (SEGUENZA, 1876) is a poorly known gastropod from the bathyal deposits of the Mediterranean Lower Pleistocene (Strait of Messina area). Its affinity with Homalopoma globuloides (DAUTZENBERG & FISCHER, 1896), living on the bathyal bottoms of the Northeast Atlantic Ocean (Azores...
