Bernaya chathamensis Cernohorsky, 1971 , p. 117 , fig. 13. Description . Shell of small size for genus ( 36 mm ), solid, somewhat globose to subpyriform, dorsal surface uniformly convex, ventral surface weakly convex, almost flat. Posterior canal narrow, barely projecting, deeply incised; anterior canal very short, deeply incised. Spire not visible. Outer lip with 14– 16 teeth, columella lip with 12–18 teeth. Fossula well developed, smooth, broad, very slightly concave, slightly projecting, bounded by very weak terminal ridge. Dimensions .

Type locality . Flowerpot Harbour , Pitt Island , Chatham Islands , New Zealand , Red Bluff Tuff , late Paleocene /early Eocene . Occurrence and material . Pitt Island , New Zealand : Red Bluff Tuff , Flowerpot Harbour ( holotype AMNZ TM-1325 ), ( GNS GS12159 , one specimen ) ; Red Bluff Tuff, GS 12173 Rocky side, Tarawhenua Peninsula ( GNS TM8792 , one specimen ) . Remarks . Cernohorsky (1971) assigned his new species to the genus Bernaya , apparently not realising that the fossula of species assigned to that genus has a deep groove at the anterior end. His description of the fossula is quite accurate, but his figure does not show the morphology of the fossula very well, as it was not fully prepared. The holotype is refigured here, but the fossula is not very clear in the illustration (fig. 5I). Another specimen kindly provided by Dr Alan Beu has been more fully prepared and although the aperture is narrow, making photography, difficult the simple nature of the fossula can be seen (fig. 5J). The fossula is somewhat similar to that in Z. viathomsoni n. sp. and Z. decipiens (E.A. Smith, 1880 ), but is not as concave. Although much smaller, the overall morphology of this species is somewhat similar to that of Zoila friendii thersites ( Gaskoin, 1849 ) . The fossula is relatively shorter and is not as deeply concave as that of the latter species, but is otherwise similar.
