Abstract

Styliolina obtusa (Hall, 1879), only known from specimens on two slabs, is placed in synonymy with S. fissurella (Hall, 1843), a ubiquitous fossil in western New York. Styliolina spica (Hall, 1888) is known only from the holotype. This individual is about three times larger than specimens of S. fissurella (Hall); it is removed from the genus. “S.” spica is based on the broken apical end of a calcareous worm tube and is similar to Coleolus. Both of these poorly known taxa were described from different intervals in the Wanakah Shale Member of the Ludlowville Formation near Buffalo, New York.
