Aslia Rowe 1970

Aslia Rowe, 1970 We are in agreement with our colleague F.W.E. Rowe, who has suggested (personal communication) that the following two species should be transferred from the genus Ocnus Forbes, 1841, to Aslia Rowe, 1970. Because these species possess ossicles in the form of four-holed knobbed buttons and an external layer of deep quadrilocular cups, they conform more closely to Aslia in the strict sense. In contrast, Ocnus, as envisaged by Rowe (1970) and Rowe and Gates (1995) possesses buttons with more than four holes, and simple, shallow, trilocular cups.Published as part of Pawson, David L., Pawson, Doris J. & King, Rachael A., 2010, A taxonomic guide to the Echinodermata of the South Atlantic Bight, USA: 1.
