Actiniade, however, agrees closely; but in his larger work (’60) 
he separated it into two families, —the Antheade, characterized 
by possessing no acrorhagi, and the Actiniadz, which did possess 
them. Of the forms which he included under the former family, 
Azptasia has already been shown to be a Sagartid; Axthea (A. 
cereus) has been shown to possess acrorhagi, which are not, 
however, conspicuously colored; the Actznza pustulata of Dana 
is a Phymactis; and Actinopsis has been referred by Andres 
(83) to an entirely different family. The three genera referred 
to the Actinidz suffer a similar dispersion, the genus Actinza 
being the only one which truly belongs to the family. Verrill 
in his earlier papers adopted Gosse’s arrangement, but subse- 
quently united the two families under the term Actinine, includ- 
ing, however, certain forms which should certainly be separated. 
Andres likewise unites Anthea and Actinia in one family, but 
established another, Cereactide, for a form not possessing 
acrorhagi. This I do not consider necessary, since, as will be 
shown, the internal structure of the members of the genus 
Cereactis (Condylactis) is similar to that of the Antheas and Ac- 
tinias so far as is known. 
Gosse’s original name, Actiniadz, would perhaps be preferable 
to that employed, since the generic term Azthea ought appar- 
ently to be replaced by Amemonia, which has the priority. On 
account of its similarity, however, to the term employed to 
designate the sub-tribe, but especially since Antheadz has 
already been used by R. Hertwig (82) with the same limitations 
as are applied to it here, I have thought it well to retain the 
latter name.

Antheade, with the column smooth or slightly verrucose 
towards the upper part. Margin elevated slightly, so as to 
form a collar; not provided with acrorhagi.
