Notes on Species of North American Oligochaeta.

III. List of Species found in Illinois, and Descriptions of Illinois Tubificidae

Abstract

A list of the earthworms found in North America was published in 1888 by Garman in Vol. III. of this Bulletin, in which those mentioned as occurring in Illinois are three species of Luvibricidce, one of Acanthodrilidae, and one of Perichaeta which had become established in the University greenhouses. To these must now be added seven other species, most of which have been described since Garman's paper appeared.
