ANTHOZOA OF THE WOODS HOLE REOION. 



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 the 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 differ somewhat, that of A. Agassiz showing a ratlier 

 large oral end, and tapering to a rather small roimded 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 fiUTows and "trans- 

 verse wrinkles, by means of which it fastens itself securely among the 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.

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 XLi 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 figiu-e 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 horn's. 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 antilliensis, and cites observ'ations of Duchassaing and 

 Michelotti of a similar trait in Cystiadis eugenia. 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 occturence in nature may not 

 be unusual. (Cf. also Gosse on this feature, p. 144.)
