Milne-Edwards removed the Polyzoa; the group was soon further thinned by the exclusion of the Protozoa on the one hand and the Entozoa on the other; while in 1848 Leuckart and Frey clearly distinguished the Coelenterata from the Echinodermata as a separate sub-kingdom, thus condemning the usage by which the term still continued to be applied to these two groups at least.
The Inguaeones again are defined as being " next to the ocean "; but the name can be traced only in Denmark and Sweden, where we find the eponymous hero Ing and the god Yngvi (Frey) respectively.
Indeed, such may very well have been the case with Frey, the chief god of the North after Thor and Odin.
The origin of the family is traced to the god Frey, son of Niorar, who is said to have founded Upsala, the ancient capital of Sweden.
Their father, Niiir6r, the god of wealth, who is a somewhat less important figure, corresponds in name to the goddess Nerthus (Hertha), who in ancient times was worshipped by a number of tribes, including the Angli, round the coasts of the southern Baltic. Tacitus describes her as " Mother Earth," and the account which he gives of her cult bears a somewhat remarkable resemblance to the ceremonies associated in later times with Frey.
