    • n dentalium The typical and leading genus of the family Dentaliidæ. Different limits have been assigned to it. By the older conchologists it was used for all the Dentaliidæ, or forms with tusk-like shells; but more recently it has been restricted to Dentaliidæ with the posterior end of the tusk-like shell furnished with an internal slightly projecting tube provided with a dorsoventrally elongated opening.
