Coelorinchus sp.

( Fig. 4V, W )

Material. Three large, strongly eroded and incomplete specimens, NRM-PZ P.15911, P.15983.

Occurrence. Site IAA 1/90, La Meseta Formation, Seymour Island, Antarctica.

Description. These large otoliths up to at least 9 mm in length are readily recognized by their strongly expanded predorsal lobe and the strongly convex inner face and strongly concave outer face.

Remarks. They represent no doubt a third, yet undescribed species, but none of the specimens are wellenough preserved to serve as the type specimen.
