The completeness of the above list is mainly due to the researches of Duchassaing, 

 and to the very complete collections made during the voyages of the " Blake " and 

 " Hassler," which have been described by Pourtales. The area is particularly rich in 

 species having an obscure type of polyp (associated with elongate spines on the axis), 

 nearly all of which it is now proposed should be referred to the new genus Aphanipathes. 

 It is interesting to note that none of the species of this genus, which have the spines 

 longer in the zooidal regions, have as yet been found outside this area. It appears pro- 

 bable that Parantipathes larix (Esp.) has been erroneously recorded from the West 

 Indies by Milne-Edwards, Duchassaing, and others. The species was not included 

 amongst the collections of the various United States Exploring Expeditions, nor does 

 it appear clear that the species was actually obtained by Duchassaing. The fact that 

 Aphanipathes barbadensis, n. sp., has a type of branching almost indistinguishable at 

 first sight from that of Parantipathes larix (Esp.), renders it probable that the two 

 species may have been confused by eaidier investigators. Leiopathes glaberrima (Esp.), 

 M.-Edw.,is the only Old World species which is definitely known to occur in the West 

 Indies. Antipathella gracilis (Gray) was recorded from Madeira by Gray, but the only 

 specimen which I have seen is from the West Indies, and Gray's type does not appear to 

 be preserved in the British Museum. All the unbranched species now recorded from this 

 area appear to belong to the genus Stichopathes ; at any rate none of them have the 

 stouter form of axis prevalent in the genus Cirripathes. 



IV. South Atlantic. 



Stichopathes filiformis (Gray). 

 Aphanipathes pennacea (Pall.). 



Schizopathes crassa, n. sp. 

 Taxipathes recta, n. sp. 



Dendrobrachia fallax, n. sp. 



No species of Antipatharia have, so far as I am aware, been previously recorded 

 from the South Atlantic. Stichopathes filiformis (Gray) was originally described from
