MATERIAL EXAMINED: NZOI Stns A448, A449, A451, A457, A458, A459, A460, A461, A464, A466, A469, A530, A536, A537; Stanford University Stns GLD-14, GLD-15; Eltanin Stns 410, 412, 416, 426, 671, 102, 1079, 1082, 1878, 1885, 1901, 1903, 1916, 2035, 2046, 2051, 2054, 2064, 2065, 2076, 2105, 2143; Richardson Stns 11, 20, 21, 22, 24, 31, 34; Yelcho Stn 7-2-8m 64°52'S, 65°47'W, 218 m .
DISTRIBUTION: Propeleda longicaudata is a characteristic, widely distributed antarctic bivalve. Around the continent it has been recorded from 90°E to 145ºE, from the Ross Sea, the Bellingshausen Sea, and the Antarctic Peninsula extending to the South Shetlands, South Orkneys and South Georgia. Throughout its range it has been collected in 64-1180 m, and in the Ross Sea in 64-930 m.
REMARKS: A single slightly damaged specimen from Eltanin Stn 2143, off the Antipodes Islands in 2010-2100 m, is indistinguishable from specimens from the Ross Sea. If further material sustains this identification, this represents a considerable extension of the known range.”
