Southwest Florida Shells with Emphasis on Sanibel & Captiva

By José H. Leal

Family Conidae

Conasprella stearnsii

(Conrad, 1869)

Dusky Cone

Shell size to 26 mm; smallest of the local species of cone snails. The shell is similar to the Caribbean C. jaspideus, but more slender and with spiral lines only on anterior half. Was considered by some authors as a shallow-water, or inshore, subspecies of C. jaspideus. The Dusky Cone differs from Conasprella pealii by its narrower last whorl, darker color, often with white spiral dashes or dots, and relatively shorter last whorl.
