exposed to the light. Corynactis^ subjected to a long fast, were at last 
reduced to the size of a pin’s head, &c. 
In Antipathes larix, Koch (5 a) describes the structure of the polypes: 
six conical tentacula, two large septa with filaments and ovaria, the other 
rudimentary, the spinous horny axis (the axial canal of which is, as in 
Isis, not continued to those of the branches), surrounded by an ecto- 
dermal (?) epithelium. 
Genera and Species. 
Actinaria (Polyactinia) . 
(ActiniiDjE). Under the name of Gepliyra dohrni, g. & sp. nn., and 
as the phylogenetic starting-point of the Antipatharia, G. v. Koch (5 a) 
describe^ a small Actinia from the Mediterranean (Naples), with about 
80 conical tentacles, growing socially on /s^s-stems. enveloping these, 
coalescing with its apposed margins (also with its neighbours), and secret- 
ing a corneous layer from its investing base around the enclosed foreign 
polypary. [^Cf. the account given in Zocl. Rec. xiv. Ccd., p. 4, of similar 
deep-sea forms attached to Mopsecc and Gorgoniidos : Actinia ahyssicola 
and gelatinosa'].
