Excerpt from Fresh Water Sponges: A Monograph <p>My design in the preparation of the present paper has been, primarily, to describe those genera and species, mostly North American, that have been discovered since the date of Mr. Carter's publication; next, to detail the results of a somewhat extended examination into the character and variations, in North America, of those species that have long been familiarly known in Europe; and thirdly, to make it valuable for reference as a Monograph, by adding brief technical descriptions of all other good species.158 proceedings OF the academy OF [1887. <p>About the Publisher <p>Forgotten Books publishes hundreds of thousands of rare and classic books.
