(Jenaische Zeitschr. XXIII, 1899, fig. 27) for Nephthya semperi. The large spindles are those 
characteristic of Studeriotes, and the largest ones measured were 6 mm. long. A common breadth 
of the large spindles is 0.4 mm. Very characteristic is the beginning of a sigmoid curve on 
many of the spindles. 
From the same locality a much contracted colony, with precisely similar spicules. 
A larger specimen, also from Station 240, showed a stalk portion of 5.5 cm. and a 
main stem reaching to 16 cm. and giving off 30 finger-like flaccid branches. The stem and 
branches show a semi-transparency. 
Another specimen, from Station 240, has a total height of 12.5 cm., of which the firm 
stalk portion occupies 3.4 cm. The flaccid contractile part gives off irregularly at different levels 
about a dozen branches, the longest of which is 4.1 cm., with a diameter of 5 mm. including 
the projecting polyps. 
Another specimen from the same station has a total height of 17 cm., of which 4.5 cm. 
is made up of non-contractile stalk. The main stem of the flaccid contractile polyparium gives 
off numerous branches which are in a state of marked contraction so that the polyps lie close 
together. The maximum length of these contracted branches is 1 cm. 
The colour of the stalk portion is a yellowish brown and the flaccid stem and branches 
are a creamy white. 
Previously recorded from China Sea.

Two specimens from Kwandang Bay, along with four of S', spinosa n. sp., stand out 
markedly as a new species. The finer specimen has a strong involucre or super-calyx, thickly 
armoured with the usual massive spindles, some of which are a centimetre in length. It stands 
9.8 cm. in height, with a width of 3 cm. and a maximum though somewhat collapsed thickness 
of 3.6 cm. The general colour is greyish brown. 
From the mouth of the involucre there protrudes a much branched umber-coloured 
polyparium, rising to a height of 5.3 cm., and bearing about two dozen finger-like branches, 
altogether covered by the long polyps. But much of the polyparium is not protruded at all. A 
common length for a branch or lappet is 2 cm., with a breadth of 4 mm. 
The polyps occur in serried rows, sometimes in distinct whorls. They are unusually long, 
on an average 1.7 mm., and are slighty incurved. 
The dorsal surface of the anthocodia is supported by chevroned rows of 3—-4 pairs of 
short spindles, which are continued on to the dorsal surface of the tentacles. On the ventral 
appressed surface of the anthocodia the spiculation is usually sparse and irregular, but points 
are occasionally to be seen. In the larger specimen the supporting bundle is represented 
merely by a short peak at the very base of the polyp. In the other specimen this is continued 
as a triangle for a short distance up the polyp. It comes to this, that the supporting bundle 
is at most relatively very short, with sometimes 3 or 4 pairs of spindles in chevron. 
The large spindles of the involucre are of the usual Studeriotes type. The polyps and 
their tentacles show small very warty spindles, varying from 0.09 mm.—0.6 mm.
