REPORT ON ACTINIARIA. 2^" 



arranged in cycles of different orders, those corresponding to 

 the primary tentacles being the largest. Whether this arrange- 

 ment of the fronds is a matter for generic distinction seems to 

 me. however, exceedingly doubtful; in an earlier paper ('89) 

 I accepted it as such, but the opportunities I have since had 

 for studying members of the familv Phyllactidas have led me 

 to modify my opinion in this respect. It seems to me that 

 the shape and structure of the fronds is a more substantial 

 feature for generic distinction than mere differences in the 

 development of the primary, secondary and other cycles, and I 

 cannot see that the structure of the fronds of the present 

 species differs sufficiently from what occurs in Oulactis to 

 warrant its separation from that genus. Whether the fronds 

 of A. bradleyi differ sufficientlv from those of Oulactis to 

 warrant a new genus must remain a question until opportunitv 

 is afforded for a renewed study of this form: judging from 

 Verrill's description they may be. 



I am also in doubt as to the propriety of considering this a 

 new species. Mr. Duerden has had opportunities for studying 

 living specimens, and his judgment is accordingly worthy of 

 great consideration, and I would merely suggest a possibility 

 which occurred to me when studying the Cuban specimens. 

 It is noticeable that the species seems to be fairly common on 

 the Cuban coast judging by the number collected by the Iowa 

 University expedition, and Mr. Duerden also rinds it common 

 in Jamaica; this makes me suspect that it may be identical 

 with one of the forms described bv earlier authors. With 

 none, however, does it seem to agree very closely, though it 

 seems to come nearest to O. -flosciriifera of Duchassaing and 

 Michelotti ('60). In my original description of O. jlosculifcra 

 ('89) I took it for granted that Duchassaing and Michelotti's 

 identification was correct. Andres ('83) thinks otherwise 

 and has separated the form described by these authors from 

 Lesueur's O. jlosculifcra and named it O. foliosa. Perhaps 

 after all Andres may have been right; the form which I de- 

 scribed from the Bahamas agrees fairly well as to coloration 

 with Lesueur's form, while the present form seems to agree
