6. Stichopathes seychellensis, sp.n. (Figs. 5, 5a.) 
Part of a stem 45 em. long without the base. It is straight and tapers gradually from 
1 mm. at the base. 
The polyps (fig. 5 a) are set close together, the largest being about 1:2 mm. in diameter ; 
they are round, with arms of medium length, with circular mouths set on a small pro- 
minence. Younger polyps are intercalated here and there. 
The spines (fig. 5) are arranged in eleven steep spirals and differ in size on the two 
sides of the stem, the longer ones being on the polyp-bearing side. The larger measure 
0-2 mm., the smaller being about half that size. They project at right angles to the 
stem, but in parts tend to point upwards. Both inside and outside spines are triangular 
and rather compressed. 
Locality. Seychelles, F 3, 39 fathoms. 
7. Stichopathes litkeni, Brook. 
One nearly complete specimen with base. The lower part of the axis is straight for

larger on one side. Other portions of colonies are present in the collection.
