[NL., ζῷον , an animal.] A genus of mono- geneous trematode worms infesting the gills of fishes. D. paradoxum is an example. The animal is double, two individuals being fused together to form an X- shaped double organism, the posterior ends of which have two large suckers divided into four pits. The solitary young are known as diporpæ ; they have a ventral sucker and a dorsal papilla, by which the junction of two ind i- viduals is effected, the sucker of one receiving the dorsal papilla of the other. The sexually matured double ani- mals lay eggs at fixed periods, usually in the spring. The eggs are furnished with very long coiled threads. The embryos when hatched enter upon the diporpa-stage, there having two eye-spots and lateral and posterior cilia, See diporpa.

Tensions and pre ures in solid bodies, extensions, compre ions and distortions, and most of the optical, electrical, and magnetic properties of crystallized bodies are dipolar quantities. Clerk Maxwell , Elect. and Mag., § 381. Along the axis of a crystal of quartz there is dipolar symmetry; along the lines of force in a transparent diamagnetic there is dipolar asymmetry.
