Abstract
More than fifty years since a great impulse was given to the study of a new and strange group of Palæozoic Arthropoda whose remains were almost simultaneously brought to light in New York, in England, Scotland, and in the Baltic island of Oesel, and attracted the attention of numerous palæontologists both in this country and in America. Among others may be cited Hugh Miller and the elder Agassiz, who at first believed them to be fish (1844), but the latter afterwards was convinced that they were in reality the remains of an enormous Crustacean.
