The detailed taxonomy of Lower Lias (Lower Jurassic) Bivalves from the South Wales area is discussed along with additional material from South West England. Particular attention is given to investigating the degree of variation shown within bivalve populations, which has here been expressed in the form of both statistical data and graphical representation. Two subspecies are described - one of them - Chlamys (c.) valoniensis penarthensis - is new, 48 species are described - Chlamys (C.) lavernockensis; Antiquilima laurae; Platymyoidea morrisi - are new. Three new subgenera are described - Modiolus (Cyranus); Camptonectes (Gandalfus); Chlamys (Copeipecten). The genus Atreta is moved from the family Plicatulidae to the family Dimyidae based on new evidence of musculature. The genus Mactromya is moved from the family Mactromyidae to the family Edmondiidae based on hinge characteristics. As Mactromya is the type genus of the family Mactromyidae the family name is abandoned and the name Mactromyopsidae proposed as a substitute family name with the genus Mactromyopsis Chavan (1959) as type genus. A correction is made to the designated type species of Ctenostreon based on new evidence from the literature.
