Scanning Electron Micrograph

Skenea species [see Lee (2009: 58; species no. 268)]

    Sorted from drift taken at 16th Avenue S., Jacksonville Beach, Florida by Norma Bulock in 11/81 (0.68 mm.) - a rather worn specimen.  Scanning electron micrograph performed under the auspices of the Dept. of Invertebrates of the United States National Museum with the excellent technical assistance of Ms. Yolanda Villacampa.

Skenea species [see Lee (2009: 58; species no. 268)]

    In shell grit taken by SCUBA from a depth of 69 feet off Boynton Beach, Palm Beach Co., FL. David Kirsh image.

    Delicate even spiral sculpture, more evident on the base, apparent with high magnification. Operculum of  specimen from Pinellas Co. is thin, corneous, and multispiral. This is Lissospira spec. indet. A (Odé 1987: 110), Ganesa (Lissospira) sp. Gundersen (1998), and Lissospira sp. (Redfern, 2013: 22, no. 60.). As pointed out by W. G. Lyons (in litt., 9/11/91), the systematic position of this skeniform taxon may be in the Turbinidae or Tornidae.

    This species is represented in the Lee Collection from Duval, St. Johns, Palm Beach, Monroe, Collier, Lee, Charlotte, Pinellas, and Levy Cos., FL as well as Sunset Beach, NC, Bahamas, Grenada, and Caribbean Colombia. The Pliocene Skenea smithfieldensis (Olsson, 1916) as treated by Campbell (1993: 57, pl. 25, figs. 246; see also Micromollusks of the Lower Pinecrest Beds, Upper Tamiami Formation, Sarasota County, Florida D3) is similar but appears to be proportionately taller and have a larger aperture.
