The characteristics of this species are : 
(1) the margin of the disc is much convoluted, but the folds are not numerous or high; yet 
the degree of folding depends largely on age and size; 
(2) the surface is smooth and rubbery, the openings of the siphonozooids are only slightly 
depressed; 
(3) there are about 6 autozooids to a centimetre on a large colony, but 8 or more in a small 
colony, which shows that this character is very unimportant. 
The spicules include : 
(a) numerous broad, almost oblong, cylinders with in most cases two median zones and two 
terminal clusters of very large compound tubercles; in a minority there are three zones. 
Average dimensions are 0.25X0.1 mm. In some of the practically oval multi-tuberculate 
spicules there is a slight suggestion of a median waist, and thus there is an approximation 
to a double sphere; 
(fi) numerous slender spindles, with relatively few conical prominences, in most cases simple, 
0.27 X 0.02 mm.; 
(r) forms intermediate between) ( a ) and ( b ), 0.25 X 0.06 mm.; 
( d ) somewhat indefinite clubs, bearing more numerous prominences at the broader end, 
o. 1 X 0.04 mm.; 
(e) small irregular crosses; 
(f) a few almost smooth small spindles, 0.08X0.01 mm. 
Of the specimens from Station 37 the larger colony stands 6 cm. in maximum height, and 
has a disc with a length of 17 cm. and a breadth of 10.5 cm. The colour is light brown. 
The smallest colony stands about 2.5 cm., and the dimensions of its disc are 5 cm. by 2 cm. 
A small brownish mushroom-like colony of this variable species from Kaniungan Ketjil 
stands 2.5 cm. in maximum height, of which 2.1 cm. go to the stalk. The diameters of the disc 
are 1.8 cm. and 1 cm. The spicules of the stalk consist largely of broad spindles and cylinders, 
chiefly rounded at the ends, densely covered with compound warts, occasionally with a median 
waist. We are regarding the presence of broad heavily-warted round-ended, 
or obtuse cylinders as diagnostic of this species, as compared, for instance, 
with 5 . glaucum. On the capitulum there are numerous narrow spindles with prominences not 
very crowded, usually simple cones, occasionally compound. 
A compact brown colony, from Station 127, with a much folded disc (8 main folds) 
overarching a substantial trunk, agrees well with the descriptions given by Marenzeller and
