II.—On Herpetopora, a New Genus Containing Three New Species of Cretaceous Cheilostome Polyzoa

Abstract

In a report on a visit of the Geologists' Association to the exhibits of Polyzoa and Corals in the Geological Department of the British Museum in February, 1913, the author had occasion to mention two related and unnamed species of uniserial Chalk Polyzoa that hitherto had appeared in records as Hippothoa dispersa (von Hagenow). neither of which was this species, nor did either belong to the genus Hippothoa, Lamouroux. Since one of these two forms is very common in the English Chalk and the other not rare, it is time for a description of them to be published, that collectors may have distinctive names for them. In addition, a third form that has occurred in England is described, and the rest of the species included in the genus are mentioned, so that an idea of the genus as a whole may be formed.
