Klunzinger emphasises the large size of the spinose double-spheres, 0.08—0.096 mm. in 
length. The maximum size in the majority of our specimens was 0.08 mm.; but the agreement 
in form is perfect. In the small specimen from Station 313 the large spicules attained a length 
of 0.1 mm. 
A specimen from Station 163 is slightly divergent as regards the knobbed “double-sphere” 
or “double club” type of spicule, for the smooth neck portion is longer and there is thus an 
approximation to the type characteristic of L. brachyclados which are nearer double-knobbed 
cylinders with a much longer smooth neck portion. But this specimen also includes the short¬ 
necked forms characteristic of L. pachyclados. 
A small colony from Station 215 with a height of 2.8 cm. and diameters of 4.3 and 
3.3 cm. has diverging non-crowded lobes which however are rather less stout, and redivide 
into a rather greater number of small rounded lobes than in the more typical specimens. The 
spicules agree well.

For description see: KLUNZINGER, Korallthiere des Rothen Meeres, 1877, p. 22, 1 fig. 
Stat. . Illegible. 1 Ex. 
A whitish grey colony, 5.2 cm. long, by 5 cm. broad, with a maximum height of 1.8 cm. 
This species belongs to the series with broad spherical lobes, flattened on the surface, 
and compressed against one another, often showing constriction. (1) The larger spicules are 
dumb-bells with rounded or pointed terminal roughnesses and a somewhat short smooth waist. 
(2) Numerous miniature dumb-bells occur, evidently young stages, often with a waist-portion 
much elongated. (3) The smallest spicules are opaque, finger-biscuit-like, or figure-of-eight-like, 
smooth or with minute asperities, with only a slight waist. The colour is greyish-white. There 
are about 8 polyps to 5 mm. 
Dimensions of the spicules are as follows: 
(1) a maximum size of 0.095 X 0.05 mm. 
(2) 0.06 X 0.03 mm. 
(3) 0.05 X 0.02 mm. 
Previously recorded from Red Sea. 
6. Lobularia globuliferoides n. sp. (Plate VIII, Fig. 4; Plate XXI, Fig. 5). 
Stat. 125. Sawan, Siau-island. Up to 27 M. Stone and some Lithothamnion. 2 Ex. 
A greyish-white colony with markedly rounded, broad and short lobes, touching one 
another. One of the lobes is produced into a curious tapering finger. The colony has a length 
and breadth of 2.5 cm., and stands 1.1 cm. in maximum height. The average apical diameter 
of a lobe is 0.6 cm. The polyps are large and sharply defined, with about 7 in a line of 5 mm. 
Besides the short roundish lobes, superficially somewhat flattened, with contiguous sharply 
defined polyps, about 7 in a line of 5 mm., this species shows as its distinctive features, («) large
