ACTINID^. 55 



tractecl. Polyps all on the same side of the flabellum, on the swellings 

 of the branchlets, aljout one diameter apart. Tentacles very short, 

 when contracted forming small knobs shorter than the spines, and placed 

 in two rows, the mouth appearing between the middle pair. 



The spines surrounding the polyp are larger than those in other parts 

 of the branches ; the largest appear inside the polyp, in the spaces 

 between the tentacles. Mouth surmounting a tubercle surrounded by 

 about twelve papillae in a close circle ; a second circle of papilla on the 

 peristome just inside of the tentacles ; similar ones are scattered on the 

 whole surface of the sarcosome. 



Height 10 to 12 cm., spread 12 to 14 cm. 



Off Havana, in 270 fathoms. 



Fragments of another subflabellate Antipathes were brought up from 

 68 fathoms, west of Tortugas, different from A. JmmiUs. There is not 

 enough of it, however, to give a full description.

Antipathes lenta Pourt. 



Mode of branching unknown. Pinnules very long and slender, like 

 thin horse-hair, not in a regular pinnate arrangement ; spines in num- 

 ber intermediate between A. larix and A. siihpinnata, as figured by 

 Lacaze-Duthiers, but somewhat longer, and straighter than in either. 



Polyps of the same type than those of A. dissccfa, but very much 

 smaller, and appear more distant from each other ; the longitudinal and 

 transverse diameters are more disproportionate than in the preceding 

 species, and the tentacles show more the tendency of arranging them- 

 selves in two parallel rows. The alternance of large and small polyps, 

 though not very regular, is quite noticeable, and the disproportion of 

 size of the two kinds veiy great. Only a few branchlets of this species 

 were obtained, some of them 10 to 12 centimeters long, without much 

 diminution of diameter. 



Off Carysfort Reef, in 35 fathoms. 

 Off' Tortugas, in 3 7 fathoms. 



Family ACTINIDiE M.-Edw. & Haime. 



This family is represented by five species in our deep waters, namely, 

 two Actiniae, two Palythoa3, and one Ilyanthus. The almost insuperable 

 difficulty of determining satisfactorily animals of this flimily from much 

 contracted alcoholic specimens will prevent anything more than a 

 simple notice, without attempt at naming them.
