. The earthworms (lumbricidae and sparganophilidae) of Ontario . seminal vesicles (Fr. vesieules seminales f.) (sv) The storage sacs for an earthworm's own sperm until copulation. septum (pi. septa) (Fr. cloison f.) (sep) The internal partition at intersegmental furrows. Also acts as a supporting membrane for internal organs (Fig. 2). seta (Fr. soie f.) (s) A solid rod or bristle se- creted by cells at the ental end of a tubular epidermal ingrowth, the setal follicle. Setae are of several types: 1) general: sigmoid shape with pointed outer tip; 2) genital: asso- ciated with genital tumescences

Individual setae are referred to as a, b, c, dy as shown in the first diagram of this Glossary, a being the most ventral and d the most lateral of the setae on a particular segment.
