Abstract
Three new marine, intertidal species of Lumbricillus are described from oligochaete collections taken in British Columbia. Lumbricillus tsimpseanis sp.nov., which was collected in upper intertidal habitats near Prince Rupert, is similar in morphology and habitat to L. helgolandicus Michaelsen emend. Nielsen and Christensen and L. kamtschatkanus Michaelsen, but is characterized by gland cells both around the spermathecal orifice and along its ectal duct. Specimens of Lumbricillus curtus sp.nov., a small species, were collected from three well-separated silty upper intertidal habitats. It is characterized by enlarged posterior lobes of the pharyngeal (=septal) glands of 6/7 and by spermathecae which unite with the oesophagus at one-half V. Lumbricillus rupertensis sp.nov., from intertidal silty sediments with much wood debris near Prince Rupert, is similar to L. lineatus with which it was found, but is characterized by a globular ampullar expansion lateral to the connection of the spermatheca with the oesophagus.
