IV.—Archæastacus (Eryon) Willemœsii, a New Genus and Species of Eryonidæ1

Published online by Cambridge University Press:  01 May 2009

Extract

The several species of Eryon, described by various authors, appear to be distinguishable as separate genera, which are as definable from one another as from the recent forms of Polycheles and Willemœsia; but the variability appears not to be greater than in those that are separated in time through geological æons, than in those that are contemporaneous in geographical space.
