Verconella ormesi Powell A W B, 1927 Penion cuvierianus jeakingsi (Powell, 1947)[1] Penion ormesi is a species of very large predatory sea snail or whelk, a marine gastropod mollusc in the family Austrosiphonidae.

[3] P. ormesi is benthic, and typically inhabits soft-sediments on the continental shelf.

[4] Recent genetic and geometric morphometric research using shell shape and size has demonstrated that a formerly recognised species Penion cuvierianus jeakingsi is closely related to Penion ormesi, and the taxon has been synonymised.

[1] However, further genetic and morphological variation observed among these snails suggests that there may be further diversity within this lineage.

[1] The species is endemic to New Zealand and is found in the Cook Strait and off the west coast of the South Island.
