The three other colonies are 3.5 cm., 3 cm., and 3 cm., in height. The sterile stalk is 
not so long and the coloration is different, otherwise they are identical with the preceding. The 
general colour of the coenenchyma is white, but the spicules of the smaller branches and those 
of the anthocodiae are orange yellow.

Diagnosis : Divaricate; rigid ; outline irregular; distinctly flattened ; polyps loosely spaced ; 
polyp stalks long; supporting bundle very strong; point spicules one pair only, with one 
member stronger than the other and projecting somewhat; pseudo-crown of about 5 rows closely 
packed together; grade VI; spicules: small dumb-bells; very tuberculate small spindles; pseudo¬ 
clubs and large warty spindles. 
Anthocodial Grade and Formula: 
VI = 2 P -f 4—5 Cr -f- strong S. B. 
Descriptive Notes: 
Colony as a whole. Two approximately rigid, bright orange, young colonies. 
Branching. Markedly divaricate; outline irregular and flattened. 
Colouring. Bright orange as a whole. 
Polyp stalks long. Polyps divergent and loosely spaced. 
Polyp spicules. The anthocodial armature show's 4—5 horizontal spindles closely packed 
in a pseudo-crown and a pair of converging spindles in each of the eight points, one member 
of the pair often larger than the other and projecting a little beyond the polyp. The supporting 
bundle is very strong, and one of its spindles may attain a length of 3 mm. 
Other spicules. The spicules of the sterile stalk are very characteristic. They consist of 
(a) small dumb-bells; (as the knobs of these dumb-bells increase in size the constriction disappears 
and the resulting spicule is a somewhat globular very knobby form): ( b ) small very tuberculate 
spindles which lead to (z) pseudo-clubs. There are also large warty spindles, relatively few in number. 
Deduction : In general branching and in anthocodial armature these specimens approach 
D. cervicornis , but the spicules ot the sterile stalk are so different and distinctive that we are 
compelled to establish a new species.
