Schrank 1803 nor Leach 18 18). In 1858, W. Stimpson gave this species a new name (Amer. Journ. Sci., vol. 25, p. 125). T. elucens Mighels might be this species, although it is very doubtful. Tellina texana Dall replaces this species in the Gulf of Mexico. It has more distinct, crowded concentric lines, is more inflated and has very small, microscopic striae in most specimens. Compare with T. versicolor.
