from The Century Dictionary and Cyclopedia
- n. In zoology, the saddle of an annelid, as the earthworm; a peculiar glandular ring around the body, resulting from the swelling and other modification of certain segments.
And their clitellum, a smooth band that all worms have, is in a different location.
Let us be like that famous Don Juan of the animal kingdom, the ten-hearted earthworm, and cultivate as many loves as our biology (or clockworks) will allow - then secrete a viscid egg sac into our clitellum and slide that junk right off our segmented, slithery body.
