Type species of Fyfea Finlay & Marwick, 1937
Classification: Turbinellidae: Vasinae?
Description: Very small for family (height 9-12 mm), broadly ovate. Protoconch described as "conoid-papillate". Teleoconch of 4-5 whorls, those on spire flat to slightly convex; last whorl with rounded periphery, base strongly excavated with a short, curved neck. Axial sculpture (apart from growth lines) normally absent, but some shells with weak nodules or costae on early whorls, persisting onto last whorl of a few specimens. Spiral sculpture of narrow cords with interspaces similar in width to cords or somewhat wider, about 30 on last whorl. Aperture pyriform with short siphonal canal; inner lip thickly but narrowly callused in adults, smooth except for a low fold at top of siphonal canal. Outer lip thin, gently sinuous.
Comparison: Until recently, Fyfea was known only from the Paleocene of New Zealand. A second species, F. tuberculata, was described from Wangaloa it differs from F. lirata in having fewer but stronger spiral cords, particularly on the base of the last whorl, and prominent peripheral nodules. The available material suggests that it is a distinct taxon rather than a variant of F. lirata. Griffin & Hünicken (1994) named another species from early Paleocene rocks of southern Argentina.
Distribution: Wangaloan, Boulder Hill (type) (common); Wangaloa (rare).
