    Abstract

    WHEN the first volume of this Catalogue was published in 1928, the earliest cirriped known was Eolepas from the Rhætic. A much earlier form has since been discovered in the middle Carboniferous of the Donez and Kusnetzk Basins, U.S.S.R. This is a Lepadomorph barnacle, and it shows that the Cirripedia must already have been in existence for a long period, but gives no evidence of the origin of the group. Among many interesting points in phylogeny the author brings forward evidence to show that the three sub-orders of the sessile Cirripedes (the Brachylepadomorpha, the Verrucomorpha and the Balanomorpha) have been derived independently from a pedunculate stock. The Cirripedes show a great development in the Chalk, where nearly a hundred species and varieties are known, but there is an unaccountable imperfection of the record in the Lower Cretaceous deposits, in which only six species have been found ; this makes it difficult to connect some of the Jurassic forms with those of the Cretaceous.
