Synopsis

Notes On The Radiata In The Museum Of Yale College, With Descriptions Of New Genera And Species by Addison Emery Verrill offers a comprehensive catalog and taxonomic treatment of Radiata in the Yale collection and related Western Hemisphere material, with additional observations from Brazil’s Abrolhos Reefs and Pacific coasts. A series of notes (Nos. 4–9) published between 1868 and 1871 presents descriptions of new genera and species across echinoderms and cnidarians, including corals (Gorgonidae, Leptogorgia, Psammogorgia, Pocillipora, Porites, Montipora, and others), soft corals (Stylasteridae, Alcyonidae), Pennatulaceans, and several starfish, sea urchins, and brittle stars. Verrill details morphological characters, such as cell structures, spicula arrangements, and the architecture of coenenchyma and calicles, and comments on biogeography, noting Brazilian fauna’s distinctiveness relative to West Indian and Indo-Pacific taxa. The work highlights newly described taxa and discusses Alcyonaria, Oculinidae, and related groups, contributing to the understanding of Radiata biogeography and taxonomy in the Americas.
