Gepyrea is a name formerly given to a class of worms which included three families: (1) Priapulidae; (2) Sipunculidae; (3) Echiuridae. The three families have little in common, and the class Gephyrea has ceased to exist in strict systematic zoology. This illustration shows and example from each of the three families: (1) Priapulus caudatus; (2) Sipunculus nudus; (3) Echiurus Pallasi.

A secant is "a line which cuts a figure in any way. Specifically, in trigonometry, a line from the center of a circle through one extremity of an arc (whose secant it is said to be) to the tangent from the other extremity of the same arc; or the ratio of this line to the radius; the reciprocal of the cosine. The ratio of AB to AD is the secant of the angle A; and AB is the secant of the arc CD." —Whitney, 1889
