ANTIPATHARIA. 
The following species were collected. 
Antipathes (Cirrhipathes) Desbonnii Ducu € 1۰ 
The describers lay particular stress on this species not forming a spiral ; our 
specimens are, however, always in that form. The axis has six rows of spines. 
The polyps are placed so as to cover four of the rows ; they are large, crowded, 
and, as 1 have remarked in a former paper, are alternately, but not regularly, 
large and small. Eggs were found in one of the larger ones, thus rendering it 
probable that they and the smaller ones are of different sexes. The tentacles 
are large and fleshy, but in the polyps near the base of the stem they become 
obsolete, although the mouths can be plainly distinguished. 
Those from greater depths are by far the largest, reaching a length of 1.3 m. 
with a diameter at base of only 2.5 mm.

Antipathes (Arachnopathes) columnaris Duon. 
The polyps are small and difficult to see ; they are of the sessile type, the ten- 
tacles appearing only as small knobs disposed in three pairs on the branchlets, 
but are spread out on the stem. Two specimens in the number are destitute 
of the parasitic worm and of the tube produced by it ; their branchlets are 
more spiny, but the general shape is the same,

curred in the North and South Atlantic, near the ice barrier in the Southern Sea, 
off the West Indies, in the North and South Pacific Oceans, and among the Moluccas. 
]t has a more extended range in depth than almost any other animal, having been 
obtained by us in thirty fathoms off Bermudas, and at all intermediate depths down 
to 2,900 fathoms. . . . . It occurs on all kinds of bottom. . . . . It sustains a range 
of temperature from 1° to 20°C,” (Sir Wyville Thomson in “The Voyage of the 
Challenger.")
