Column smooth, or nearly so, sometimes sulcated vertically. Wall 

 imperforate and destitute of verrucie and suckers. No acontia. Mar- 

 gin with or without colored tubercles. Tentacles usually numerous, 

 long, mostly contractile, sometimes non-retractile. 



The existence of numerous forms combining the characters of .Ic- 

 tinia and Ant/iea {Anemonia) appears to require the union of these 

 seemingly very diverse genera into one subfamily. 



Owing to the difficulty in ascertaining the existence of acontia and 

 lateral pores in preserved specimens, some species referred to the Sa- 

 gartln B may belong here, while some of the species referred here may 

 belong to Sagai'tia. 



Paractis Edw. and Haime, op. cit., p. 248, (restricted). 



Column smooth, imperforate. Tentacles retractile ; no marginal 

 tubercles. 



This genus was established for numerous species supposed to have 

 these characters, but as most of them were known only by figures and 

 descriptions, many species were wrongly placed in it. Thus of 19 

 species referred to the genus, some of them doul)tfully however, by 

 Edwards and Haime, at least 12 appear to be Sagartians, and most of 

 the others are of doubtful affinities. 



Whether a genus having the characters assigned to this really ex- 

 ists, may, therefore, be reasonably doubted. But as species occur 

 which apparently agree with the diagnosis and cannot well be referred 

 elsewhere, it may be best to place them provisionally in this genus, 

 until better known. , 



Paractis (?) nobilis Verrill, sp. no v. 



Column changeable in form, subcylindrical or somewhat elongated 

 and pillar-like in expansion, capable of contracting to the form of a low 

 cone. Surface, in preserved specimens, smoothish in expansion, when 

 partly contracted the lower part of the column is covered with close, 

 deep, transverse wrinkles, becoming more irregular and reticulated 

 above, the upper part with about 48 vertical raised folds or wrinkles, 

 which by contraction are l)ent in a zigzag manner. Margin with a 

 distinct fold, crenated by the vertical folds. Tentacles of moderate 

 size, about 48 in number.
