A Monograph Of The Fresh-Water Polyzoa is a complete and exhaustive work by the eminent naturalist George James Allman, published by the Ray Society in 1856. This monograph discusses in great detail the anatomy, physiology and homologies of the Polyzoa before advancing to the zoographical element of his piece; including his subject's behaviour and classification. A prominent academic, Allman produced this monograph during his tenure as Professor of Botany at the Royal Academical Institution, Belfast.
