ANTHOZOA OF THE WOODS HOLE REGION. 
239 
species: “ Surface nearly smooth, slightly sulcated lengthwise, color pale flesh color, or pink, translucent. 
Tentacles numerous, short, tapering, pale greenish olive, with dark band around tire base, connecting 
with a dark line radiating from mouth. ” To this the author adds that its size when extended is 3 or 4 
inches long, by about i inch in diameter.

Though reported by Agassiz and Verrill as more or less common in its relation as a parasite or com- 
mensal on Cyanea arctica, the writer has not found it on any specimens taken at Woods Hole. Verrill 
also reports it as having been found buried in gravel at low water at Eastport, Me. So far as I am aware, 
it has not been reported south of Cape Cod. Not having seen living specimens of the species the follow- 
ing description is compiled in part from the accounts of Agassiz and Verrill, and in 
part from specimens loaned by Mr. George M. Gray, who collected them at Eastport, 
Me. The figure was drawn from these specimens. 
Figures of the shape as given diSer somewhat, that of A. Agassiz showing a rather 
large oral end, and tapering to a rather small rounded point at the aboral. Accord- 
ing to Verrill, it is more nearly barrel shaped. The size is about 35 mm. in length 
by about 10 mm. in largest diameter. Body with longitudinal furrows and “trans- 
verse wrinkles, by means of which it fastens itself securely among tlie fluted mem- 
branes around the mouth of the jellyfish. ” It is said to live for some time in confine- 
ment, where it attaches itself “for its whole length to the vessel in which it is kept, 
and clinging quite firmly if any attempt is made to remove it.” This mode of 
adherence may be taken to imply the presence of such suckers as are more or less 
common in several otlier species of actinians. According to Verrill, it resembles 
very closely species of Peachia as described by Gosse. 
ANEMONIA Risso, 1826 . 
Anemonia sargassensis Hargitt. [PI. xu, fig. 3.] 
Anemonia sargassensis Hargitt, Biological Bulletin, vol. xiv, p. 117, 1908. 
This anemone was briefly described in a recent note (vide supra), and some refer- 
ence made to its habitat. Several other points call for further elucidation. Figure 
3 of plate XBi shows well the general aspects of the creature and its mode of attachment to the 
gulf weed which forms apparently its chief or only habitat. The figure was made from life and 
gives approximately the color and aspects of average specimens. The base is adapted to clasping 
the stems of the weed to which it adheres with great tenacity. It is also able to creep along 
from place to place by means of the disk, though it does this only occasionally. A specimen in 
the aquarium was observed to remain in one identical spot for more than 30 hours. Another 
feature, more or less rare, is that of inflating the pedal disk, and thus making of it a float by means 
of which the creature may drift oral end downward, indefinitely. Duerden (1902) reports a similar 
habit in Bunodosoma spherulata, Bunodeopsis antilUensis , and cites observations of Duchassaing and 
Michelotti of a similar trait in Cystiactis eiigenia. I have occasionally observed the same thing in 
several other actinians, but only in the artificial conditions of the aquarium ; and it may not yet be 
improbable that this has something to do with the performance, yet its occurrence in nature may not 
be unusual. (Cf. also Gosse on this feature, p. 144.)
