Remarks

Talassia sandersoni was described from off Cape Hatteras (Verrill 1884) and is found off the Atlantic coast of the USA and into the eastern Gulf of Mexico; in NMNH the syntypes (USNM 34447) are stored as well as two more lots from off Cape Hatteras and six lots from off Florida (Rosenberg 2009; this study). The syntype (USNM 34447) was depicted by Warén & Bouchet (1988: fig. 48). The teleoconchs are covered by spirally dotted cordlets of irregular strength and weakly flexuous growth lines (Figs 12– 21).
