2. Alcyonium inolle n. sp. (Plate VIII, Fig. 3; Plate XXIV, Fig. 4). 
Stat. 60. Haingsisi. Reef. Lithothamnion in 3 M. and less. 1 Ex. 
A whitish-grey colony with a short stalk portion (1.2 cm) and two main divisions bearing- 
short finger-like branches. The polyps are very thickly disposed, and most of them are completely 
contracted. The canal walls are abundantly filled with relatively short broad warty spindles, 
but the whole texture of the pliable colony is soft. As might be expected the characteristic 
feature is in the spiculation. Most of the spicules are finger-biscuit-like, very warty spindles, 
some blunt, some tapering to a point (0.2 X 0.06 mm.). Besides these there are some slender 
spindles (0.16 X 0.02 mm.). Some spheroidal sandy inclusions occur somewhat deceptively. There 
are no clubs nor zones of warts. A few spindles show a slight indication of a girdle. Most of 
the warts are low hillocks and none seem to be compound. The colony is softer in texture 
than A. simplex ; the zooids are less crowded; the spicules are all rougher; there is a frequent 
occurrence of blunt-ended spicules. 
3. Alcyonium rotundum n. sp. (Plate XII, Fig. 1 ; Plate XXIV, P'ig. 8). 
Stat. 60. Haingsisi, Samau Strand. 1 Ex. 
A cream-coloured colony standing 14.7 cm. in height, of which about 4.5 cm. goes to 
substantial sterile trunk. The diameters of the base are 5.5 cm. and 4.3 cm. The trunk gives 
off three main branches spread out almost in one plane. These divide and redivide eventually 
into numerous elongated finger-like lobes which tend to occur in somewhat flattened groups one 
behind the other, and may again bear minor lobes. A common length of a finger is 2.7 cm. 
The zooids begin to arise directly from the top of the trunk, and they cover the branches so 
densely that, as in A. simplex , there is practically no bare space. They show a diameter of 
about 0.8 mm. The consistency of the colony may be described as firm and fleshy, and the 
interior in the preserved specimen is very compact. 
The distinctive feature of this species is of course in the spicules which differ markedly 
from those of A. simplex and A. molle. 
They consist mostly of short, broad, rough ovoid and spindle-shaped forms, usually blunt- 
ended and rotund, but sometimes tapering, densely covered with prominences, sometimes pointed 
cones and sometimes obtuse slightly compound roughnesses. Average dimensions are 0.14 X 
0.08 mm. An occasional cross occurs. There are no narrow delicate spindles. Many of the 
ovoids and spindles show the beginning of a median waist, but none of them could be confused 
for a moment with the minute dumb-bells which mark the genus Lobularia. But this species 
may be regarded as at the end of a series — A. simplex , A. inolle , A. intermedium. 
4. Alcyonium simplex n. sp. (Plate VIII, Fig. 2; Plate XXIII, Fig. 3). 
Stat. 47a. Bay of Bima. Shore. 1 Ex. 
A much branched greyish-white colony, with short, blunt, somewhat conical lobes entirely 
covered with crowded monomorphic zooids. A short sterile trunk, with basal diameters of 4.2 cm. 
by about 3 cm., gives off almost immediately three main branches, which at once subdivide
