REPORT ON THE ANTIPATHARIA. 175 



are arranged on the stem in such a manner that the whole of each of the series, one, two, 

 and three, are almost parallel with one another, giving a very regular growth. The 

 primary branches are relatively close set, about three or four to a centimetre. 



The spines are apparently short and much crowded, showing a subverticillate arrange- 

 ment (cf. Koch, 76, pi. ii. fig. 5, b). 



This species appears very closely allied to Antipathes spinescens, Gray, if, indeed, it 

 be not identical with it ; both types come from the same area. 



Habitat. — Rolas (Gulf of Guinea), Koch. 



The following species are too imperfectly defined for identification : — 



[Antipathes] alopecuroides, E. and S. 



Antipathes alopecur aides, Ellis and Solander, Zoophytes, p. 102. 



" Antipathes ramosa, ramis arete paniculatis hispidis setaceis. 



" The trunk of this Antipathes rises from a broad spread base, and divides immediately 

 into several large branches of ^ of an inch diameter; .... one side of them appears flat, 

 with a groove or channel along the middle of it, where there are the remains of many 

 little branches that have grown in rows on each side of it. It then divides into branches, 

 and often into other branches, all which are in form of close panicles, not unlike the fox 

 tail grass. These panicles are composed of very rough, thorny, minute branches, which 



are twice as long on one side of the stem as the other It is near 2 feet 



high" (Op. cit.). 



Habitat. — Off South Carolina. 



[Antipathes] triquetra, Brug. 



Antipathes triquetra, Bruguiere, EncycL method., p. 82 ; Lamouroux, Polyp, flex., p. 374. 



"A. subflexuosa ; ramis raris ; ramubs subspiralibus, triquetris" (Brug., op. cit.). 



Stem simple, very thick, bearing three or four branches irregularly, which, like the 

 stem, have a somewhat triangular outline. " On appercoit sur la create des angles qui des- 

 crivent une spirale autour de la tige et des rameaux, des impressions assez serrees qui 

 designent les pinnules dont les angles etaient garnis, et dont il reste en quelques 

 endroits une faillie dun quart de ligne ; tout la superficie est herissee de poils bruns 

 roides et courts, sur lesquels on voit par intervalles des croutes muqueuses qui les 

 couvrent en partie" (Brug., he. cit.). 



Habitat. — Manila (Poivre).
