 Turbonilla (Pyrgiscus) buteonis Bartsch, 1909 Hawk Turbonille
    In shell/bryozoan hash from one fathom off the town of Cedar Key, Levy County, Florida, 5/2019 (2.59 mm.). SEMs produced in collaboration with Dr. Ann Heatherington, Dept. Geological Sciences, University of Florida, Gainesville, FL.
    Salient characters of this shell include the seemingly teratologic rapidly-expanding profile from very slender apex and the waxy luster with fine secondary spiral scratches atop irregular and variable spiral ridges. Redescribed by E. N. Powell (1981), who compared it to T. viridaria Dall, 1884. A synonym is T. kurtzii Maz˙ck, 1913, but T. interrupta (Totten, 1835) is not synonymous (despite Abbott, 1974 and others). This is T. (P.) sp. A Lyons (1989b) [vidi] from St. Lucie Co. T. pocahontasae Henderson and Bartsch, 1914 from Virginia may be a subadult specimen of this species. Collected from 40-175 ft. off NE Florida (Lee, 2009: 146; species no. 702) and also found in MA (Bartsch, 1909), VA to SC (Powell, 1981); NC, GA, and Levy Co. (Lee Collection). Not recorded from Florida by Camp, Lyons, and Perkins (1998).
