Ligament internal, valves lighter, thin and sharp at edges. Size moderate or large, pallial sinus reaching J to 1 distance to anterior muscle scar. Dish shell Spisula p. 54 dd. Animal asymmetrical with valves unlike especially at siphonate end; shell usually thin and weak particularly at margins (least marked in Semele and Tellina) ; siphons separate, slender and very Ions: forms deeply bur- rowing in sand or mud where they are found lying on the side, e. Ligament wholly external; pallial sinus united with pallial line; shells generally thin, f. Shell elongated (about twice as long as wide), neriostracum not con- spicuous, shell not conspicuously thin, whitish with fine but very distinct and regular growth lines, siphonate end bent to the right. Tellen Tellina boclegensis p. 42 ; pi, 11 , fig. 1.
