With regard to Sea-anemones, Crustaceans, etc., Dr. 

 Irving of Scarborough writes : ' I saw no Actinia mesem- 

 hryanthemum (common beadlet), and can only account for its 

 apparent absence in the neighbourhood where I worked by the 

 fact that there were no exposed rocks where it could have 

 regular air and sun-baths — the zone was beyond its usual 

 range. Other anemones however, were numerous. Those I 

 saw were : — 



Tealia crassicornis v. meloides. 



,, V. insignis. 



,, V. aiirea. 



Dianthus plumosa (young specimens, 

 salmon colour).

Crustaceans abound : —

I chipped off a small white patch from a rock which I thought 

 was a young colony of Alcyoniitm digitatum. It measured 

 perhaps \ inch by \ inch. Examining it at home, I found about
