No. 1.] ACTINIARIA OF THE BAHAMAS. 55 
rence in Phymanthus is consequently interesting. In structure 
(Pl. IV., Fig. 10) it is essentially similar to what Hertwig has 
described ; 2.¢., it consists of peculiarly modified endodermal 
cells which stain deeply, and are consequently very evident in 
sections. I am unable to say whether the filamental apparatus 
is present in the ovaries likewise of these forms, since all the 
specimens examined were males. 
This form seems to occur throughout the whole range of the 
West Indies. Lesueur (17) observed it at Barbadoes, and 
Duchassaing and Michelotti at the same island and also at St. 
Thomas. There can be no doubt as to the identity of the forms 
described by these authors with that obtained by me in the 
Bahamas. A figure is given by Duchassaing and Michelotti 
(66) which has apparently been overlooked by Andres. It is 
evidently, however, of a contracted specimen, and cannot be 
considered a good representation. The animal figured by Ellis 
(’67) without description, and named Actinza aster, has never 
been sufficiently characterized to permit of identification, al- 
though it has been included by many systematic authors in their 
review of the Actinians. The description given by Solander 
(86) is very meagre, and includes no specific characters; and 
Duchassaing and Michelotti (60 and ’66) simply mention it, 
without any description. Judging from the figure given by 
Ellis, it seems possible that it may be identical with Phyman- 
thus crucifer; but the uncertainty of such an identification is 
too great to warrant the insertion of the name among the syno- 
nyms given above.
