The cnidce in this species attain a higher development 

 than in any other zoophyte that I am acquainted with, and 

 hence they afford peculiar facilities for the study of these 

 interesting organs. 



No one familiar with this beautiful little creature can 

 for a moment doubt that the two supposed species, viridis 

 and Allmanni, are in truth but one. The former name 

 must of course be retained, as having the claim of priority. 

 It was given by the discoverer, Professor Allman, who 

 found it, where since it has been so abundantly met with 

 by Dr. E. P. Wright. The name Corynactis is formed 

 from icopvvr), a club, and uteris, a ray. 



There are several exotic species, whose tentacles are 

 tipped with globose knobs; — as Act globulosa (Quoy et 

 Gaim.), A. globulifera (Ehrenb.), and A. clavigera (Dana) ; 

 but I know too little of their structure to pronounce upon 

 their degree of affinity with the present. The clavigera, 

 a species of large size from the Pacific Islands, may 

 perhaps be a link of connexion between Corynactis and 

 Sagartia.
