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 Alhnanni, 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 KopvvT], a club, and uktU, a ray. 
There are several exotic species, whose tentacles are 
tipped with globose knobs ; — as Act. gldbidosa (Qnoy et 
Gaim.), A. globidifera (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.
