When mature, a precisely located swollen area of the epidermis called a clitellum secretes a cocoon in which the eggs or ova are deposited. These are usually fertilized and there is development within the egg without a free larval stage, the newly- hatched worms resembling the adults.

He concluded that sixteen sample units of an area of 1/16 m. taken to a depth of 20 cm gave an adequate estimation of a population of medium-sized species. For larger worms and deeper samples, a larger area of deeper sample was required.
