186 Notes on Some Actinians from the Bahama Islands, 



Family DENDROMELID^. 



In my earlier paper ('89) on West Indian Actiniaria I proposed 

 a new sub-tribe Dendromelinse for the reception of the peculiar form 

 Lehrunea neglecta discovered by Duchassaing and Miehelotti 

 ('60) and proposed to place in it also the genus Ophiodiscus de- 

 scribed bj' R. Hertwig ('82). Since that time I have come to the 

 conclusion that I gave the group too high a mark and have sug- 

 gested ('93} its reduction to a family of the sub-tribe Actininse. 

 With the two forms already mentioned it seems that a third 

 should be associated, namel^^, the Hoplophoria coralligens de- 

 scribed by H. y. Wilson ('90), which, as I have already pointed 

 out elsewhere ('93), seems to be identical with the Viatrix glohu- 

 lifera described by Duchassaing and Miehelotti ('60). 



Lebrunea neglecta Duch. & Mich. (1860). 



A single specimen of this form was in the collection and being 

 unwilling to injure it, I have nothing to add to the description 

 of the structure given in my earlier paper. It may be stated, 

 however, that the number of pseudotentacles is in this individual 

 six, just as they were in the other specimens examined ; one, how- 

 ever, is considerably smaller than the others. 



Family PHYLLACTID^. 

 Diplactis bermudensis McMurrieh. (1889). 



This species I described ('89a) originally from alcoholic speci- 

 mens from the Bermudas and was pleased to find it represented 

 in the present collection by several specimens, together with a 

 drawing (here reproduced in pi. xvii, fig. 3) and a description of 

 the living animal. I have nothing to add to my original account 

 of the anatomical characteristics of the species, but am able to 

 complete it by abstracting from Dr. Northrop's notes a descrip- 

 tion of the coloration and form of the living animal. 



The column is chocolate brown in color, and when the animal is 

 expanded has a greater diameter at the base and at the upper part 

 than in the middle of its length, the upper part forming a slight 

 parapet projecting above the level of the disc. The tentacles are 

 brownish red in color and the disc rufous, that is to say, some- 

 what paler than the tentacles. The papillas which represent the 

 fronds Dr. IN'orthrop apparently overlooked, inasmuch as they
