pseudo-clubs and numerous slender spindles with simple prominences. Superficially, however, there 
is a close resemblance, especially in the folding of the capitulum. 
In the spicules of a specimen from Jedan Island there were included amongst the warted 
spindles some rather stouter pointed spindles (0.32 X 0.09 mm.). 
A very small colony from Station 144, Damar, seems to us to be a young form of this 
species. The total height is 2.4 cm. ; the stalk with an average diameter of 8 mm. shows a deep 
fold at one side which is continued into the capitulum. The remainder of the capitular margin 
is slightly lobate. The autozooids, about 2 mm. apart in the centre, but more crowded round 
the edge, are distinct, but it is difficult to distinguish the siphonozooids. The texture is gritty 
and the colour is a deep cream.

It has not been found possible to refer to any of the numerous described species two 
specimens from Station 142. They are marked by the following features: 
(1) the disc does not extend far beyond the relatively broad stalk, a character that suggests 
reference to the latum-ehrenbergi group; 
(2) the very small siphonozooids occur in more than one row (2 — 3) between the relatively large 
closely set autozooids : 
(3) the stalk-spicules are shuttle-like spindles (up to 0.36X0.1 mm.) with somewhat distant zoned 
warts, the zones increasing with size from two to five, and the warts passing from simple 
cones to the blunt compound type. Although many small young forms occur, the general 
impression is of homogeneity. There are none of the typical very heavily warted X. troche- 
liophorum type, and none of the large long spindles of X. glaucum ; 
(4) along with the shuttles are small cortical clubs, with sparsely warted stalks, 0.13 mm. in 
average length; 
(5) the capitulum includes numerous narrow elongated rods, sparsely warted and sometimes almost 
smooth (up to 0.4 mm. long and 0.03 mm. broad). Some are straight and others bent. There 
are also cortical clubs of diverse sizes. 
The best specimen has a height of 7.3 cm., of which 7 cm. goes to the stalk. The 
maximum breadth of the stalk, which is rather flattened, is 2.8 cm. The diameters of the capi¬ 
tulum are 4 cm. and 2.7 cm. The texture is spongy, the colour grey-brown.

We base this new species on its spiculation exclusively. A mushroom-like form with a 
pronouncedly thick stalk and a well defined slightly lobed capitulum. The stalk is 4.2 cm. in 
height, and expands above its attachment to a thickness of 3 cm. The diameters of the capitu¬ 
lum are 3.5 cm. and 4 cm. Over the surface there are numerous retracted autozooids, about 
0.5 mm. in diameter, and minute siphonozooids, requiring a lens for their detection, fill up the 
interspaces. The surface is distinctly rough. 
The distinctive feature is the large number of long very delicate spindles, with relatively
