* Perhaps the most magnificent Actinia known is A. Pau- 
motensis, described and figured in Dana’s “ Zoophytes.” It 
was found at the Isle of Raraka, in the Pauniotu group, by 
the naturalists attached to the American Exploring Expe- 
dition. It is twelve inches in diameter of disk, which is 
deeply frilled. 
A. reticulata, from Terra del Fuego, is another fine and 
richly coloured species ; with a frilled disk, and tentacles 
very numerous and fringe-like. Both these must doubtless 
be assigned to the genus Actinoloba. 
A. Achates, a species dredged by the same Expedition, in 
thirty fathoms, on the east coast of Patagonia, has the 
frilled character of dianthus, with but three rows of ten- 
tacles, which are not specially crowded. It is evidently 
intermediate between dianthus and hellis ; but further 
examination is necessary to determine to which genus it 
rightly belongs. 
I may, however, venture to exhibit the affinities of our 
Anemone in the following gradation ; distinguishing exotic 
species by [ ] ; —
