Introduction

In the preparation of the present monograph my purpose has been to give descriptions and figures of all the species of isopodous Crustacea, marine, terrestrial, and fresh-water, known to North America, with synopses, so as to assist the student in the identification of each species. The descriptions are made as concise and as nearly uniform as possible. The original descriptions have been prepared primarily from specimens in the collection of the U. S. National Museum, but have been supplemented by specimens from other museums.
