FORSTER COOPER—ANTIPATHARIA. 313 
Polyps are unfortunately absent. 
The spines on the main stem and main branches are very minute, never exceeding 
0°05 mm. They are arranged in four rows, but on the larger branches are so small as 
practically to be non-existent. On the secondary branches, or “ bushes,” they are 
longer, attaining a length of 0°2 mm., and are thin-pointed and needle-like in shape. 
Locality. Lat. 7 4’ N., long. 79° 32’ E., 590 fathoms (‘ Investigator’ Collection). 
15. Antipathes abies (Linn.), Gray. (Fig. 9.) 
var. paniculata, Esper. (Fig. 9a.) 
Colonies of the “ bottle brush” type, cylindrical and usually tapering at the top. In 
some specimens there are two main stems, the division taking place at the bottom of the 
colony ; when this occurs one stem is always the larger, the other being subsidiary. 
The branches are arranged roughly in a spiral around the stem, and the distance 
between them is irregular. The diameter of the main stem is uniform throughout, 
except at the extreme tip, where it tapers to a point. 
Fig. 9. 
There are two types of branching, which, however, are connected together by inter- 
mediate forms. In the first (abies, fig. 9) the branches are stout and open, and the 
subsidiary branches bend sharply at various angles along their course. In the second 
(paniculata, fig. 9 a) the branches are more lax, not so stout, and the subsidiary branches, 
which all arise from the upper surface of the branch, are not angulated in their 
course. 
The polyps have been described by Thomson and Simpson. In height the colonies 
average from 10-15 cm. 
Localities. Seychelles, 37-44 fathoms ; Amirantes, 20-39 fathoms; Cargados Carajos, 
45 fathoms; Table Island, Andamans, 15-35 fathoms (‘ Investigator’ Collection).
