A History of British Mollusca, and Their Shells, by E. Forbes and S. Hanley

A History Of British Mollusca, And Their Shells, By E. Forbes And S. Hanley is a dense, plate-supported taxonomic reference from Britain’s 19th-century conchology tradition. The work consolidates corrections, updates, and new observations across major molluscan groups found around the British Isles, with emphasis on shell morphology and, where known, soft-part anatomy. It traverses Acephala (bivalves) with revised identifications and localities, Tunicata, and Pteropoda, and introduces a new treatment of Gasteropoda Prosobranchiata as a unifying section. The text details Chitonidae with an extensive treatment of Chiton species, Patellidae including various limpets, and Calyptrida and related genera such as Calyptraea and Calyptraea sinensis, among others. Additional notes cover Dentaliidae and Dentaliiformes, and broader discussions touch on higher-level classifications and debates about Gastropoda boundaries, the place of Chitons and Pteropods, and the interplay of morphology, dentition, and anatomy in species delimitation. Geographic distribution around Britain, boreal–Mediterranean ranges, fossil occurrences, and nomenclatural priorities are repeatedly addressed to refine identifications and future plates.
