A Monograph On the Sub-Class Cirripedia: The Lepadidæ; Or, Pedunculated Cirripedes

The book features two pivotal studies on barnacles, published in 1851 and 1854, that significantly contributed to Charles Darwin's standing as a leading taxonomist and biologist. These works not only showcase his meticulous research and classification skills but also lay the groundwork for his later theories in evolution. Through detailed observations and descriptions, Darwin's studies reveal the complexity of barnacle species, highlighting his innovative approach to biological classification and the broader implications for natural history.
