Extract

The prostates or spermiducal glands form a prominent feature in the anatomy of the large family of the Megascolecidæ. Occurring in the neighbourhood of the termination of the sperm-ducts, they assume one of two forms, the tubular or the lobular. In the first, the gland typically takes the form of a bent, undulating, or coiled tube, cylindrical, with a single central lumen; in the second, it consists of a loosely or tightly packed aggregate of lobules, each with its ductule. The prostatic duct is in the first case a continuation of the glandular tube; in the second, the duct is formed by the union of the ductules; in both cases it is as a rule firm and muscular.
