Family Haloclavid^e Yer. nov. 



Column much elongated, either smooth or with suckers ; 

 base with a very small or rudimentary disk; tentacles 20, 

 obtuse or capitate ; ten pairs of mesenteries, all perfect. 



Haloclava, gen. nov. Type H. producta (Stimp.) Yer. Figure 7. 



Column much elongated, soft, without a sheath, the upper 

 part with rows of distinct adhesive suckers. Upper end with 

 a sphincter and capable of involution. Aboral end often 

 inflated or bulbous, with a rudimentary disk, capable of adhe- 

 sion to small pebbles. Tentacles twenty, short, usually clavate, 

 nearly equal, marginal. Mesenteries very muscular, all perfect,

arranged in 10 pairs ; six of these pairs are larger and form a 

 regular primary cycle ; four other pairs, narrower below, 

 belong to the second cycle ; the usual pair, next to the ventral 

 or sulcar pair of directives, is lacking on each side. 



Besides the type species this genus will include II. albida 

 Yer., which I now consider only a variety. H. Capensis Yer., 

 Commun. Essex Inst., v, p. 5, pi. 3, tig. 7, 1869 ;* H. brevi- 

 cornis (Stimp.) Yer., op. cit., p. 4, pi. 3, figs. 2, 2 a , 2 & ; and H. 

 Stimpsoni Yer., op. cit., p. 5, pi. 3, fig. 1, 1869, resemble this 

 genus but probably belong to Eloactis Andres. No specimens 



* Andres, in his classical work on the Actinaria, has entirely overlooked my 

 two illustrated articles on Actinaria of the North Pacific Expl. Expedition, in the 

 Comm. Essex Inst., vols, v and vi, 1868, 1869, quoted above, and has, therefore, 

 omitted one of the above named species from his work, as well as numerous 

 other species and several genera first described and illustrated in those papers. 

 In several cases he stated that no figures nor descriptions of certain species 

 therein described had been published. Nevertheless he quotes those papers in 

 his bibliography. In the papers referred to there are four plates of Actiniae (40 

 figures). He also failed to quote several other papers by me. Among those 

 omitted are Report on Invert, of Vineyard Sound, etc., 1874; Radiata from Coast 

 of North Carolina, this Journal, iii, p. 432, 1872 ; Bulletin, U. S. Nat. Mus., No. 

 15, 1879; American Naturalist, ii, p. 251, and several others. He intended to 

 include all the literature and all known species. Such omissious are liablo to 

 happen in the best works.
