NOTE ON THE MESENTERIES OF ACTINIANS. 553 



the too wide statement made in the '' Revision of British 

 Actiniae " would have been corrected by Professor Haddon if 

 he had had an opportunity of seeing the proofs of it; un- 

 fortunately, however, he started for Torres Straits immediately 

 after it was read. 



It thus is evident that the type represented by Sagartia, 

 Actinia, and Bunodes is separated from the type represented 

 by Manicina (Wilson), Ariactis (McMurrich), and perhaps 

 also Euphyllia (Haddon), merely by observations of Lacaze- 

 Duthiers which were made without sections. 



I can only add my regret that this mistake should have 

 caused so much confusion.
