? Corynascidia sp.

Material examined

St. 2120, 8330– 8430 m, one specimen in poor condition and one empty test.

Remarks

This is the deepest record for the Ascidiacea. The specimens are in very poor condition and details of their morphology are obscured. The completely mutilated branchial sac seems to have spiral unciliated stigmata. The median position of the small gut loop suggests Corynascidia . The specimens are sessile, without a stalk. These specimens were referred by Vinogradova (1969) as probably belonging to Situla pelliculosa Vinogradova, 1969 . The specimens, however, have two distinct siphons with numerous lobes, very different from Situla .
