formalin. An examination of the literature at hand failed to give 

 any clue as to their specific, or even generic relations. Subse- 

 quent investigation pointed to more or less close affinities of the 

 genus Anemonia, of Risso. But there seems little doubt of the 

 fact that the species has not hitherto been described. The fol- 

 lowing summary of characters will suffice for its general features, 

 and a more detailed account of its anatomical features will shortly 

 be published in another communication. 



Column short and irregular in shape, about half as high as 

 broad. Column obscurely fluted, and with pedal disk well de- 

 veloped and adapted to clasping the sea weed, to which it adhered 

 with tenacity. Oral disk characterized by a series of white or 

 cream-colored radiating lines extending from the mouth to the 

 bases of tentacles or even slightly outward on the bases of the 

 larger ones. 



Tentacles cylindrical in shape, but slightly contractile, though 

 more or less prehensile at the distal portions ; the number vary- 

 ing with size, from 25 to 30 in smaller specimens, to about 50 

 in the larger, and in length from 5 to 15 mm., tapering to acutish 

 ends, the inner series nearly twice the diameter of disk. The 

 tentacles also are definitely adhesive, sticking to anything with 

 which they come in contact. In several cases bifurcated or 

 forked tentacles were found, adding to the more or less irregu- 

 larity and asymmetry of these organs. 



There are no acontia, nor marginal tubercles. Color a more 

 or less diffused brownish or chestnut, variegated by the whitish 

 markings on tentacles and disk, giving to the creature a close 

 resemblance to the olive brownish color of the Sargassum, and 

 rendering its presence difficult of detection. It shares this feature 

 in common with perhaps the large proportion of the fauna of the 

 Sargassum forest. 



Supplementary Note. 



Since the foregoing notes were written and about to be sent to 

 press I have received Hartlaub's admirable paper " Craspedote 

 Medusen " (Part XII. of Nordisches Plankton), in which he dis- 

 cusses certain problems relating to Gemmaria and Zanclea. 

 With most of Hartlaub's views my own will be seen to be in 

 substantial agreement. Concerning his contention as to the
