PRELIMINARY DIAGNOSIS OF A NEW GENUS OF MARINE ISOPOD (FLABELLIFERA, CIROLANIDAE) BY N. L.

Diagnosis. - Cirolanidae with rostral point minute or absent; frontal lamina linear; maxilliped with single coupling hook on endite. Pleopod 2 of male with appendix masculina arising midway along inner margin of endopod; pleopods 3-5 glabrous in both sexes, and the protopod of pleopods 1-5 with external margin formed into a lobe. All pleon exposed with lateral margins free. Type species. - Pseudoldna concinna (Hale, 1 92 5 ) . Remarks. - The diagnosis allows ready separation from most cirolanid genera.
