THE SANDALLED ANEMONE. 75 



mones were hanging from "beneath the little points and 

 projecting ledges. 



In describing these specimens, I suggested the possibility 

 that they might be referred to the Actinia alba of Mr. W. 

 P. Cocks.* The absence of the bright yellow dots that 

 were found on the mouth of the latter, and the entire want 

 of visible suckers, induced me to consider mine as unde- 

 scribed. It is true, the repeated occurrence since of 

 specimens with a disk more or less yellow nullifies the 

 force of the former objection, but the latter remains ; and 

 until I see specimens of A. alba from Mr. Cocks's locality, 

 I dare not assume the identity. From original drawings 

 witli which that gentleman has kindly favoured me, I per- 

 ceive, moreover, that the tentacles in alba are numerous 

 and slender, whereas in sphyrodeta they are few, thick. 

 and conical. Besides this, the marking of the ten- 

 tacles in alba, which are described as " barred, having 

 opaque white patches anteriorly," removes the animal from 

 any species with which I am acquainted. I am not, 

 however, without hope, that before this work is closed, 

 the kindness of my Cornish friends may bring me into 

 personal acquaintance with this, and other desiderata of 

 that prolific coast. 



The substitution of another appellation for that which 

 I had at first assigned to this species was called for on two 

 accounts. First, there was already a species named Candida 

 by Miiller ; of which fact I was not aware. Secondly, 

 this name proved objectionable. While no specific name 

 may be rejected on account of its having no significance, 

 every one ought to be rejected which has a false sig- 

 nificance. Mr. Holdsworth's discoveries of the species at 

 Dartmouth and in the Channel Islands have proved, or at
