ANTIPATHAKIA. 



The following species were collected. 



Antipathes (Cirrhipathes) Desbonnii Ddch & Mich. 



The describers lay particular stress on this species not forming a spiral ; our 

 specimens are, however, always iu 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 ra. 

 with a diameter at base of only 2.5 mm.

Antipathes (Arachnopathes) columnaris Ducn. 



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.

 off the West Indies, in the North and Soutli Pacific Oceans, and among the Moluccas. 

 It has a more pxtended range iu 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 Wyvillc Thomson in "The Voyage of the 

 Challenger.")
