Mr. J. Walton on the genera Pissodes, Hypera, ^c. 295 animal and of the individual polyps wholly different from that which is found in every species of the family Brachiolites. In all the various and so greatly varying fonns which have been thus seen to be included in the genus Cephalites one end is Ibund to be subserved, namely, the maintenance of the security (if the whole mass, and of each individual of its myriads of living tenants; together with the unimpeded access of the sea-water — lliat element upon whose constant presence the life and subsist-ence of those myriads depended. The great diversity is no less striking than is, in each case, the completeness of the varying methods which nature has adopted for securing that ever-teeming, ever-active life which excites the inquirer's increased admiration at every step he takes.
