(4) the narrow but strong supporting bundle, composed of a few very long curved spindles 
(2—3 mm.), not projecting or only slightly; 
(5) the characteristic anthocodial armature. Each point consists of one or two pairs of bent 
spindles, markedly projecting in the contracted polyps. At the base of the points there is a 
pseudo-crown, often of two rows. Small spicules occur between the points. 
One specimen from Station 305 has a long, thin, rigid stalk about 13 cm. in height, with 
an almost uniform diameter of 2.5 mm. The base of the stalk is expanded irregularly. At the 
top the stalk divides into three short main branches, each of which divides into two. The total 
length of a branch and branchlet is about 1 cm. The general appearance is suggestive of a 
capitulum. The armature of the anthocodise consists of a pseudo-crown of two rows and eight 
points of one or two pairs of spindles en chevron. The general colour is whitish. The spicules 
are colourless. 
Another colony, quite evidently a young form, from Station 260, growing on a piece of 
Polyzoon, is just beginning to branch. The total height of the colony is about 1 cm., of which 
the stalk is about 3 mm. The breadth of the base is 2 mm. 
7. Stereonephthyci sierra n. sp. 
Stat. 273. Jedan Island. 1 Ex. 
A somewhat stiff though not rigid colony, markedly flattened in one plane. It consists 
of a flaccid sterile stalk 4 cm. long. At the top several small branches arise, but the expanded 
stalk is quite distinct for another 4 cm. At this level two large lateral branches arise and the 
stalk is continued upwards for another 4 cm. considerably flattened and polyp-bearing. The total 
height of the colony is 12 cm. and its maximum breadth 9.5 cm. 
From the central portion of the polyparium, as well as from the branches, small blunt 
digitiform processes are given off. On the branches themselves, as well as on the digitiform 
processes, the polyps are borne, either singly or in more or less horizontal groups of 3 — 7, like 
interrupted whorls. 
The polyps arise at an angle of about 45 0 and are directed upwards. The stalk is short 
(not over 1 mm.) and consists entirely of a strong triangular supporting bundle. The bases of 
several adjacent supporting bundles may unite in horizontal ridge-like groups, giving the appearance 
of interrupted whorls. The supporting bundle consists of from 4—6 short thick spindles arranged 
in an almost equilateral triangle. The uppermost pair project for a short distance and this 
results in a series of sierra-like ridges. 
The anthocodise lie^ in the angle formed by the supporting bundle and the stem, and in 
many cases appear as if they arose directly from the stem. They are very densely armoured 
and are completely encased in short thick spindles arranged in eight groups of three or four 
pairs. Each number is almost equally common on the colony. There is no marked specialisation 
or projection of the uppermost pair. The colour of the main stem and the larger branches is 
a greyish yellow, but in the smaller branches it is a dull white. The tips of the projecting 
spicules in the supporting bundle are pink to reddish; the spicules of the anthocodise are red 
but their tips are often whitish. The sterile stalk (and also the main stem) is distinctly arenaceous
