(Figs 4S—U, 6M, N) Material. Holotype: NRM-PZ P.15976 (Figs 4S—U, 6M, N). Paratypes: two specimens, NRM-PZ P.15977. Occurrence. Telm 5 unit; ‘ Natica horizon’, Cucullea I member, La Meseta Formation, late Ypresian, early Eocene. Site IAA 1/90, Seymour Island, Antarctica. Etymology. Named in honour of A. V. Balushkin (St Petersburg, Russia) in recognition of his contribution to the knowledge of Antarctic fishes, fossil and Recent. Diagnosis. OL:OH = 1.7. Dorsal rim with marked predorsal angle. Ventral rim moderately deeply curved, deepest anteriorly, flattened at deepest point. CCL: OCL = 1.6; CaL:OsL = 1.45. Collum moderately wide, with faint pseudocolliculum. Description. Moderately compressed and moderately thin otoliths of up to at least 6 mm in length (holotype 6.0 mm long). OH:OT = 2.7. Dorsal rim highest anteriorly above ostial collum with rather sharp predorsal angle, rim somewhat undulating, posteriorly regularly declining without prominent angle. Ventral rim deep, deepest below ostium and deepest area flattened. Anterior rim blunt, with obtuse angular tip at level of ostium; posterior rim tapering, rounded, with tip at level of cauda. Inner face moderately convex with distinctly supramedian, moderately narrow and shallow sulcus. Ostium distinctly shorter than cauda and narrower. Ostial and caudal colliculi well marked, with relatively wide collum in between; ostial colliculum usually reduced towards anterior tip of otolith. Collum narrowed from ventral with short, indistinct pseudocolliculum. Dorsal depression narrow, indistinct; no ventral furrow; dorsal and ventral fields with some radial furrows from the marginal crenulation. Outer face almost flat, with many radial furrows coalescing in a shallow umbo opposing the collum of the inner face. Remarks. A typical species of the genus Coelorinchus characterized by its rather compressed outline, the high dorsal rim and the presence of a small and short pseudocolliculum.
