EUPSAMMIAD^. 
October new moon, among the rocks off tlie Tunnels, all in 
the vicinity of the spot where I found the first. They were 
always in the same circumstances, erowded in colonies; 
one cavity, just large enough to turn in, containing perhaps 
a hundred, speckling the walls with their little scarlet disks, 
near extreme low water. Not one that I took presented 
the least variation from the charaeters I had jotted down 
already ; but one specimen had adhering to its base two 
very young ones, one about a line in diameter, the other 
not more than one-third of a line. Examination with a 
lens revealed no difference either in form or colour between 
these and the adult ; the condition of their skeleton is un- 
known, as I did not choose to destroy the infant specimen, 
much to my present regret. 
Since that time it has been found in considerable abund- 
ance along the same line of coast ; and it has become 
common in our aquariums. It is always attractive from 
its brillianey, and is moderately hardy, though it appears 
rather more difficult to keep than Caryopliyllia. 
The integuments are opaque, even when distended : 
indeed they never become filled with water to anything like 
the extent which makes the spceies just named so beautiful. 
The plates are never visible, during life, in any degree of 
contraction, the red flesh lying as an opaque cushion over 
them even when all the tentacles are withdrawn. I am 
not sure that the disk is ever wholly covered by the inver- 
sion of the eolumn ; even when the tentacles are quite con- 
eealed beneath the margin, the large mouth-eone still pro- 
trudes from the central orifice. Sometimes the tentacles 
sink to very low warts or minute yellow eminences on 
the scarlet plain that constitutes the disk. 
I have said that the epitheca is not unvarying ; and I 
think that the flesh does not extend externally below its 
edge. One in my possession, however, had the exterior of
