The colony has a very short narrow stalk, less than i cm. in length, while the polyparium 
is 5 cm. high and 4.5 cm. in breadth. It is very compact and markedly flattened in one plane. 
The lowest branches are distinctly foliaceous and form an almost uninterrupted collar. The length 
of the polyp stalk varies considerably in different parts of the colony and even in the same 
bundle. Some of the polyps have long stalks while others are practically sessile. The supporting 
bundle is strong with one spicule markedly projecting. The points consist of 4—6 pairs arranged 
very distinctly en chevron. Four, five and six pairs are equally common. 
The spicules of the lower cortex are very characteristic. They consist of: 
(a) large spindles, straight but mostly curved, some “kneed”. The most obvious feature is the 
enormous development of spines and warts on the convex side. The middle of the convex 
side is covered with compound warts, but these taper off to simple spines at the two ends. 
Some of the spindles are so dentate on the convex side that a foliaceous appearance results; 
( 5 ) some of the spindles bifurcate and give rise to triradiates of which one ray is stronger than 
the other two. These again give rise to starfish-like forms, and these again pass into multi¬ 
radiates densely covered with tuberosities; 
(z) very numerous, on a different line, are spheroidal forms with thorny prominences, derivable 
from small capstans; 
( d ) from these small capstans there also arise minute 4 — 5 rayed forms which develop into 
strong rounded multiradiates; 
(e) different from all these types are flat smooth disc-like amoeboid forms. 
This species is not far removed from D. dojieini , but nowhere throughout the whole 
colony was it possible to discover any projection of the chevron rows nor any marked exagge¬ 
ration in size of the uppermost pair. The nature of the spiculation in this species also separates 
it off quite definitely from D. dojieini. 
The colour of the colony is creamy, but the projecting spicule of the supporting bundle 
is a bright red, which gives the colony a mottled reddish appearance.
