Rh 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.

Tellina versicolor DeKay DeKay's Dwarf Tellin New York to the south half of Florida and the West Indies. /4 inch in length, very similar to T. agilis, but more elongate, colored white, red, pink or rayed, is more inflated, and has a nearly straight instead of curved ventral margin. The exterior of versicolor has a brighter irides- cence. The pallial sinus is much closer to the anterior muscle scar. Tellina mera Say Eastern Florida and the Bahamas. Mera Tellin Figure 86c /4 to % inch in length, roughly elliptical, moderately inflated, pure opaque-white in color. Fairly thin but strong. Beaks fairly large for a Tellin, touching and pointing toward each other and located nearer the posterior than the center of the shell. The valves show hardly any posterior bend or twist. Exterior smoothish with fine, irregular, concentric lines of growth more evident near the margins. Moderately common in shallow water be- tween tides. Compare with promera and tampaensis.
