   At the same time the posterior gape of the valves would lead one to expect a sinupalliate character.

1. biologyA mollusc with an indented pallial line or sinus.

   Larger suspension feeders are also very abundant, such as the endobyssate bivalve Hoernesia with shell torsion and a thick umbo used as an anchor (McGHEE, 1978), as well as the deep-burrowing sinupalliate Pleuromya.

   But even this new conception would not furnish the clew to the law of torsion as long as the hinge line is considered (as by Jackson) one radius of the angle of torsion; with Noetling's data a comparison of the valves of Nucula with any sinupalliate pelecypod valve shows, that though in both the axis of the hinge is parallel to the oro-anal axis, a torison^([sic]) of 90° of the valve of Nucula has taken place with reference to that of the sinupalliates.
