The British Woodlice: Being a Monograph of the Terrestrial Isopod Crustacea Occurring in the British Islands

"The British Woodlice" by Wilfred Mark Webb and Charles Sillem is a scientific publication written in the early 20th century. This monograph serves as a detailed examination of the terrestrial isopod crustaceans commonly found in the British Isles, focusing extensively on their morphology, classification, and ecological aspects. The authors aim to contribute to the understanding of woodlice and encourage further study into their distribution and behavior. The opening of "The British Woodlice" establishes the context and purpose of the study, acknowledging previous work on the subject while noting a lack of comprehensive literature specific to British species. It outlines the authors’ intent to provide a thorough account and illustrations of these creatures, beginning with an introduction to their geological history and biological classification. Following this, the narrative delves into specifics, including the external structure of woodlice, their circulatory and digestive systems, and reproductive organs, laying a groundwork for the intricate details that will follow in the subsequent chapters.
