Form.—A large thin-walled Actinian, when fully expanded nearly as broad as 
high. Column crowded with large, delicate, oval vesicles, the cavities of which 
communicate with the ccelenteron. Tentacles numerous, of moderate length, in 
three or four rows. Oral dise apparently of not much greater diameter than 
the column. Mouth large, circular. Pedal disc of greater diameter than the 
column, somewhat inflated. The figure is reconstructed from several slight 
sketches made by Prof. Spencer. 
Colour.—Upper part of pedal disc dark-grey, with light lines for the mesen- 
teries. The pedal disc itself is of a deep chrome-yellow or orange, becoming paler 
or yellowish-green towards the centre, the mesenteries showing as bluish-grey 
lines. Vesicles either deep chrome-yellow with bluish vertical stripes, or bluish- 
grey with light stripes. Tentacles yellow, orange, or bluish, usually yellowish at 
base, then often brownish, with a yellow tip; the chrome-yellow of the tentacles 
has not such a red tinge as that of the vesicles; space between tentacles grey. 
Oral dise yellowish, passing into orange (or even dark grey) round mouth. Inside 
of mouth grey. 
Dimensions. —About 6 inches (150 mm.) in height, 5 inches (125 mm.) in width, 
largest tentacle 1 inch (25 mm.) in length. Vesicles may be fully 1 inch (25 mm.) 
long, and } inch (13 mm.) wide. 
Locality.—Coogie, New South Wales. 
As our description of this species is drawn up from the sketches and coloured 
details sent to us by Prof. Baldwin Spencer, and from spirit specimens, we think 
it advisable to reprint Quoy and Gaimard’s original description, which supple- 
ments our own :— 
‘* Actinie tuberculeuse, Actinia tuberculosa, nob.—Actinia, turriculata, molle, 
subrubra, tuberculis ovalibus, striatis, ordinatis, ornata ; tentaculis brevibus, 
subluteis; ore rubenti.
