The taxonomy of the British Jurassic irregular echinoids is revised and updated from that given by T. Wright between 1857 and 1878. There is emphasis on cross-correlation with material from continental Europe. The British Jurassic fauna comprises 33 species in 17 genera. One new genus (Pronucleolites) and two new species (Galeropygus parviphyllus and 'Pronucleolites' crickleyensis) are described. A new cladistic analysis, incorporating all of the British taxa, provides a well resolved phylogeny for early irregular echinoids.
