Colour. Lower half pale brown or yellowish-brown, upper half 
greenish-brown. Tentacles and oral disc bronze-green. The mouth 
surrounded by a broken circle of yellow, from which extend 6 groups 
each consisting of 3 radiating yellow lines with a shorter yellow 
line between each 2 groups (Stuckey). 
Dimensions of the largest specimens: length about 2 cm, 
greatest breadth in the distal part about 1 cm, length of the inner 
tentacles about 0,5 cm. 
Occurrence. Bay of Islands. 1.1.1915. Several specimens. 
Oriental Bay, Wellington Harbour (teste Stuckey). 
Exterior aspect. The pedal disc is well developed but not 
broad. The column is pillar-like, also in contracted State higher than 
broad, and provided with distinet hollow verrucae in the upper third. 
Below it they are indistinet. They correspond to the endocoels and 
are most numerous in the vicinity of the margin, where they are 
hemisphaeric. The margin is distinet with a small fossa. At the end 
of the rows of the warts there are at least 24 very distinet marginal 
sphaerules, in the larger specimens the number of marginal sphae- 
rules is greater in connection with the development of new endocoels. 
Sometimes some sphaerules are miscarried. The tentacles are conical, 
short, at least 48, but in larger specimens to about 70 and hexam- 
erously arranged. The oral disc is wide and more than half of it 
lacking tentacles. The actinopharynx is rather short with numerous 
longitudinal ridges and 2 distinet siphonoglyphes forming well devel¬ 
oped aboral prolongations. 
Anatomical description. The anatomy of this species was 
described by Stuckey; it is, however, in some points incomplete. 
As the ectoderm of the column is not sufficiently well preserved I 
cannot decide if the verrucae are structured as those of Urticina. 
U is possible that they agree more with the biadder in Phymactis. 
In the maceration preparations of the hemisphaeric warts in the 
uppermost part of the column I namely observed rather many small 
nematocysts, but they are probably situated in the edge-zone of the 
warts. The endoderm in all parts of the body contained numerous
