Iris description it is stated that they " dichotomize many times 

 until a dendritic structure is produced." The rounded bodies 

 are not figured nor described by him, nor by D. and M. as 

 occurring on the fronds. In this respect the fronds are very 

 different from those of the Bermuda species studied by me. 

 I am, therefore, disposed to believe that there are two large 

 West Indian species. 



Subfamily Aliciin^e = Family Aliciad^: Duerden. 



Duerden, Ann. and Mag. Nat. Hist., 6, xv, p. 213, 1895; Haddon and Duerden, 

 Sci. Trans. Eoy. Dublin Soc, vi, p. 153, 1896. 



This family was established to include certain tuberculated 

 genera, such as Alicia (= Cladactis Pane), Cystiactis, etc. 



It is characterized by a thin wall ; feeble, diffused sphincter 

 muscle; hollow tubercles, usually compound, on the column ; 

 12, 24, or more pairs of perfect mesenteries ; no acontia. 



The wall-tubercles are thin and doubtless serve as branchiae ; 

 they are not adhesive suckers. 



The group is practically equivalent to tuberculated Actinidw, 

 and might well form a subfamily of that family. 



JEJucladactis Ver., new name. Type, M. grandis V. 



Cladactis Yer., Trans. Conn. Acad. Sci., i, p. 472, 1869 (non Panceri, 1868). 



By a mere coincidence the name Cladactis was given by M. 

 Panceri and myself to two distinct genera, at nearly the same 

 time. The former appears to be the same as A licia Johns, 

 which preceded it. No other name seems to have been given, 

 as yet, to my Cladactis. The latter is characterized by very 

 numerous tentacles, which are scarcely retractile ; column 

 thickly covered with hollow clavate and lobulated tubercles, 

 the upper ones larger and more lobed than the rest ; margin 

 with a deep fosse ; sphincter muscle very feeble and diffuse, or 

 almost lacking; 36, 48, or more pairs of perfect and many 

 imperfect mesenteries, having feeble muscles extending along 

 most of their breadth ; gonads numerous, borne on most of 

 the mesenteries, both perfect and imperfect; a distal septal 

 foramen; mouth large, with two large equal siphonoglyphs ; 

 lips with very numerous lateral furrows.

The larger specimens of this species are over 2 inches in 

 diameter and height, as preserved in alcohol. The tentacles
