branchings of the fifth order being sometimes attained. The distance between branches varies 

 from 5.5 cm. to 3.5 cm. thus averaging much more than in the preceding species. The ter- 

 minal twigs are much longer, reaching a length of 16 cm. The diameter of the branches 

 varies from 3 mm. to 2 mm. near tips of branches. The median grooves are evident on the 

 proximal parts of the colony, but are almost obliterated on the distal parts. The calyces are 

 emplanted on all sides of the branches, and are in oblique rows of 3 to 5, although the rows 

 are often obscured by younger calyces being intercalated between the older and larger ones. 

 In some places the calyces on one side of the branch are inclined upward, while those on the 

 other side are inclined downward : but this is e.xceptional. 



The individual calyces are club-shaped, prominent, with their distal ends enlarged and 

 inclined toward the branch. The aperture seems in general to be more strictly terminal than 

 in other species and less inclined to face the branch. This, however, may be largely due to 

 the stage of contraction of the polyp. A typical calyx measures 1.6 mm. in length and 

 1.2 mm. in diameter. There is a slight appearance of lobulation around the margin. The dorsal 

 surfaces of the tentacles are armed with small, often bar-like spindles transversely disposed. 



A cross section of a branch shows that the ccenenchyma is rather thick and the axis 

 is composed of many concentric and interrupted rings of calcareous and horny material alter- 

 nately disposed. The water-vascular canals are symmetrically disposed arround the axis, but 

 some distance outside of it. 



Spicules. These are of two kinds characteristic of the genus. The club-stars have 

 the club ends more slender, as a rule, than in the last species, and simple clubs are rather 

 common. Typical double stars are rare. Double crosses are also found, as well as an occasional 

 simple spindle. 



Color. The colony is a bright coral red throughout. The polyps are white. 



General distribution. Type locality off Japan, 345 fathoms. This species is also 

 found in the Indian Ocean. 



The .specimens referred to this species are identified with some doubt, but the one 

 de.scribed agrees fairly well with the original description, particularly as regards spiculation, 

 manner of growth and the calyces. 



Thomson and Simpson regard Juncclla ininiacca as a synonym for this species.

Colony (incomplete) subflabellate in form and attaining a height of 37.5 cm. The speci- 

 men consists apparently of one of the main branches of a much larger colony. The branching 

 is partly dichotomous and partly irregular. The main stem, or branch, is 4 mm. in diameter 

 and its first forking is 3.5 cm. above its base. The resultant branches arc quite irregular, the 

 smaller one giving off branchlets from the outer side only, while the larger one is dichotomously
