Other spicules. Those of the short stalk include, besides spindles much rougher than 
those of the anthocodiae and more curved, various triradiate and smaller irregular quadriradiate forms. 
Locality: Amboina Reef. 
The two young divaricate colonies with amber-yellow anthocodial and supporting-bundle 
spicules have distinct flattening, and show what we regard as essential characteristics of D. mollis viz. : 
(1) a very marked projection of one of the uppermost spicules of each point in the anthocodial 
armature ; 
(2) the presence of 3 or 4 other pairs of smaller spicules converging en chevron ; 
(3) the very strong supporting bundle with three specialty strong spicules, one of which projects 
bevond the others for about one millimetre; 
(4) the dense regular covering of the anthocodial, supporting-bundle, and coenenchyma spicules 
with short blunt tubercles; 
(5) the prevalence on the short stalk of much rougher spindles (straight, curved, and much 
curved), with much longer and more distant tubercles, and along with these numerous, 
irregularly shaped, roughly tuberculate forms. 
A few spindles occur with asymmetrical, bifid ends. The polyp stalks are longer than in 
the other forms. 
Locality: Station 310. 
The fragmentary, ivory-white colony, without a stalk, divaricate in type, in its branches 
inclined to be flattened, closely approaches D. mollis in showing: 
(1) a very marked projection of one of the uppermost spicules of each point; 
(2) the others (usually 3 pairs) much smaller; 
(3) a very strong supporting bundle with three specially strong spicules, one of which projects 
for at least 1 mm.; 
(4) the dense regular covering of the spicules with short, blunt tubercles. 
Most of the spicules are curved spindles, many boomerang-like; bifid and trifid forms 
occasionally occur; here and there one is almost quite smooth. 
Locality: Bay of Batavia, Java. 
In the collection there are seven other specimens which must be referred to this species : 
(1) A small colony flattened horizontally so that the outline is almost circular. Here is no trace 
of attachment. The under view shows four very much flattened bare branches, arising at 
right angles, three almost equal in size and one slightly smaller. These branches give rise to 
smaller branches and these ag^in to others, which bear the bundles of polyps. On the upper 
side branches arise all over and give the appearance of a network. The general coloration 
is a dull white with orange polyps. 
Locality: Station 289. 
(2) Two colonies each with a moderately long stalk. The polyparium is slightly flattened. The 
stalk of the larger specimen is 3.5 cm. long, and the polyparium is 3.5 cm. high and 
3.5 cm. across. In the smaller specimen the stalk is 3.5 cm. long and the polyparium 
2.5 cm. by 2.5 cm. These specimens agree in detail with the amber yellow colonies described 
above from Amboina reef. 
Locality : Station 315.
