Haddon — On the AdinicB off the 8.-W. Coast of Ireland. 371 
species from^. richardi : such, certainly, is my present opinion, but 
I prefer to leave the matter in abeyance. On the other hand, it may 
be a deeper-water variety of that species, the variation mainly con- 
sisting in a reduction in the size of the tubercles and in the basal 
bulbs of the tentacles. The specimens were preserved in a state of 
expansion. 
? Chitonactis sp. 
Column with numerous, few, or no tubercles ; when present these 
are very small, and pointed ; cuticle present or rubbed off, in latter 
case still adherent to the tubercles ; basal disc greatly expanded. 
Column low dome-shaped in contraction or much flattened, coronal 
tubercles small. 
Colour. — Some specimens " column white, with a double row of 
sparsely scattered orange tentacles, disc white, mouth and oesophagus 
deep orange " ; other specimens base white, upper part of body flesh 
colour, tentacles sparse, short, marone colour." In spirit the colour 
is whitish, cuticle greenish or brown ; in two specimens there is a 
thick persistent cuticle, which is rubbed away on the upper portion of 
the retracted body, leaving a conspicuous white crown. 
Dimensions in spirit. — Expanse of base of largest specimens 
35 mm. x 18 mm.; height, 7 mm. or less. The base is usually irre- 
gularly oval in outline. 
Mr. Kane, who was a member of the Expedition, gave me the 
colour notes which I have quoted above, as his memorandum runs : — 
*' Log. N'o. 67, 345 fathoms. Several Actiniae on Fusus islandicus, 
tenanted by Paguri ; one, however, with living animal." I assume it 
refers to these specimens. I removed one of the more cuticular speci- 
mens from a living shell of Cassidaria tyrrhena, which was obtained 
at the same time. The Actiniae were attached to several species of 
gastropods. 
A very characteristic feature of this species is its remarkable 
power of producing buds from its greatly expanded pedal disc. In 
one specimen a new polyp is being formed well within the pedal disc, 
later it appears to entirely separate itself from its parent. This bud, 
so far as I can see, arises spontaneously, and not as a constriction of 
the oral disc.
