Actiniaria. 



Professor A. C. Haddon reports as follows: — "Professor 

 Herdman submitted to me a few specimens of Actiniae 

 collected by himself when on the ' Argo ' : they consisted 

 of two species — 



"(1) Anthea cereus, Johnst., which is extremely com- 

 mon on the west coast of Ireland, especially on Zostera 

 beds, the Actinian looking like an inflorescence on the 

 Zostera. The ashy grey variety is the most common, 

 occasionally the tentacles have a distinct green sheen. 



"(2) Sagartia (?) herdmani, n. sp. (cut, fig. 1). 



" It is extremely difficult to investigate the anatomy of 

 this form owing to the greatly contracted condition of the 

 spirit specimens, and therefore I cannot yet speak with 

 confidence as to the genus. I am however pretty confi- 

 dent that this is a new species ; unfortunately I have not 

 had the opportunity of seeing it alive, nor are there any 

 sketches of the living and expanded animal. Provision-
