Harry G. Lee's response:

"I am posting to the list because James' image of these Dove Shells is excellent to spectacular (but deleted herefrom to avoid electronic burden), and the species in question is an attractive, interesting, and innominate one.  It has no name either.  It is closest to Costoanachis semiplicata (Stearns, 1873), with which it occurs where James collected it, but differs in being heavier, more brightly-colored, stockier and more angulate in profile.  In my collection I have one lot from Santa Rosa Co., FL and three from the Texas coast.

It has been illustrated at least three times in the literature:

Scheltema, A. E., 1968.  Redescriptions of Anachis avara (Say) and Anachis translirata (Ravenel) with notes on some related species (Prosobranchia, Columbellidae). Breviora 304: 1-19. Dec. 31. [plate 1, fig. 12].

Garcia-Cubas, A., 1982.  Moluscos de un sistema lagunar tropical en el sur del Golfo de México (Laguna de Términos, Campeche). Inst. Ciencias del Mar y Limnol. Univ. Nacional Autónoma de México Pub. Esp. 5: vii + 1-182 + 1 pl. (1981). [p. 57, fig. 60].

Vokes, H. E. and E. H. Vokes, 1984.  Distribution of shallow-water marine mollusca, Yucatan Peninsula, Mexico. Mesoamerican Ecological Institute, Monograph 1, Middle American Research Institute, Publication 54 (1983): i-viii + 1-183, incl. 50 pls. [plate 14, fig. 13].

It was misidentified in the two latter works.

Besides JAmes, at least three other Conch-L'ers have collected it.   I should like to hear from interested parties - publicly or privately."

I therefore call it "Costoanachis sp. aff semiplicata (Stearns, 1873), un-named."
