tember 7, three weeks after they were secured. The other speci- 

 men had not transformed on October 3, and, as far as could be 



determined, it had undergone no changes 

 in size or form. 



The actinian, of which the larva just 

 described is the immature form, is not 

 definitely known to me at present, but a 

 number of mature sea anemonies, prob- 

 ably of the genus Amophyllactis, were cast 

 upon the beach near where the larvae were 

 found during the same and subsequent 

 storms coming from the same direction. 

 Since both these forms appear only after heavy storms from- a 

 definite direction, and since there are certain structural re- 

 semblances between the young polyps and the mature actinians, 

 it seems not improbable that they may be different stages in the 

 life history of the same species.
