It seems inadvisable then to associate Halcurias with Gonac- 

 tinia and ProtantJiea, but there still remains a possible asso- 

 ciation with Hertwig's Antheomorphidae. Unfortunately the 

 forms upon which this family was founded are insufficiently 

 known, but it seems to me that there are reasons for main- 

 taining the position I have already ('98) advocated, that the 

 nearest allies of Halcurias at present known are to be found 

 in the family Antheomorphidae. I find myself obliged, how- 

 ever, to recede from the position I held in 1898 as to the dis- 

 tinctness of this family and to return to my earlier opinion, 

 which has received the approval of so critical a taxonomist as 

 Haddon ('98), that the Antheomorphidae should be included 

 in the family Actiniidae, and if this view be accepted it is 

 necessary to refer the genus Halcurias to that family also. 



This will necessitate no important modification of the defini- 

 tion of the Actiniidae given by Haddon ('98), but as I shall have 

 occasion in the immediate future to consider the family in 

 some detail, I shall postpone a discussion of its delimitation 

 for the present.
