Colour greenish or brown from reddish-brown to brownish- 
black or yellowish-green, marginal sphaerules whitish with a blue 
or lavendar tinge. Tentacles and oral disc dusky crimson or dull 
red (teste Farquhar and Stuckey). 
Dimensions. Column about 2,7 cm, diameter of the disc 
about 4 cm, length of the tentacles about 1,5 cm (Farquhar). 
The 3 largest specimens from Slipper Islands were 2, 1 — 2,5 broad 
and 1,5 cm high in preserved State. 
Occurrence. Slipper Island; low water. 20.12.14. Several 
specimens. 
New Zealand. Manakau Harbour, Cook Strait, Queen Charlotte 
Sound (Grant) Robin Hood Bay (Skelley), Stewart Island (Mor¬ 
ri son) teste Stuckey and Walton, Auckland Isl. (Kirk) teste 
Stuckey, Kermadec Islands (teste Stuckey). Port Jackson (Mor¬ 
tensen) 4 specimens. 
Exterior aspect. The exterior of this species agrees with 
that of Åctinia equina. The pedal disc is wide, the column smooth, 
its height shorter than its diameter. The margin is distinet. The 
marginal sphaerules, situated in the deep fossa, are large, in con- 
tracted State often deeply transversally furrowed so that they some- 
times look as if there were a short row of sphaerules instead of 
a single sphaerule. Their number varies in connection with the 
number of compartments. Sometimes they are miscarrying in some 
parts. The tentacles are conical, short, and arranged in several cycles. 
Their number varies. Stuckey States 200 or more. The three 
largest specimens from Slipper Islands had 144, 138 and 114 ten¬ 
tacles. More than half the oral disc lacks tentacles. The mouth 
is situated on a conus. The actinopharynx is provided with numerous 
longitudinal ridges and two well developed siphonoglyphes forming 
well developed aboral prolongations. 
Anatomical description. The anatomy of this species is 
described by Stuckey but in some points incompletely. Stuckey 
States that there is no sphineter. In faet a rather well developed 
diffuse sphineter is present, showing a tendency to form humps, 
and situated as usual in Åctinia between the tentacles and the 
marginal sphaerules. I have sectioned 2 specimens, one from the
