obtuse cone. This species in addition to being rooted is on®, 
of the most inactive of its order; for whether in a state 0 
contraction or expansion it will remain so for many days p r 
even a week without apparent chaEge. If it should be '" 
an expanded state, a touch will make it contract, and it > 
most commonly remain so for several days. Its most f®' 
vourite state, is the semi-expanded in which it will someti® eS 
remain from a week to a fortnight without change. 
The trailing connecting baud is flat, thin, narrow and ® 
the same texture as the polype and glandular. It frequently 
gets enlarged into small papillary eminences, which as tb e ; 
become enlarged, become developed into polypes. 
This species and tlie Actinia sociata of Ellis are veL v 
closely allied to each other; this, however, is shorter, sm»H eI 
and not so much pedunculated as Ellis figures his to b®» 
and the fleshy band also appears to be thinner and wider. 
Having communicated specimens to Dr. G. Johnston, * lC 
is of opinion that it is distinct from Ellis’ species, and b® 5 
done me the honour to give it the name quoted above.
