This genus resembles the geniis AntJwopsis of Simon as modified 

 by Carlgeen, except in the arrangement of the tentacles. Is is disting-- 

 uished from Adinioides of Haddon & Shackleton, by the absence 

 of triie acrorhagi and from Condyladis by the possession by the 

 latter of a "collar" in place of a parapet and of longer and stouter 

 tentacles. 



I assign to this genus the form which, since my paper of 1893, 

 has generally been termed Condyladis cruentata. Veeeill has re- 

 cently (1899) placed it in the genns Adinioides, but, as Caelgren 

 has pointed ont, the absence of triie acrorhagi excludes it from this 

 as defined by Haddon & Shackleton. It has always seemed 

 to nie a little out of place in its position under Condyladis and I 

 believe its reference to a new genus will prove more satisfactory. 



4. Purantheoiisis cruentata (Couthouy). 



Äctinia cruoitafa Couthouy, 1846; Gay, 1852, 



Cereus crueniatu.s Milne Edwaeds, 1857. 



Bunodes cruentata Gosse, 1860; Veeeill, 1869; Andees, 1883. 



Condyladis cruentata McMuerick, 1893; Caelgeen 1897 and 1899. 



Bunodactis cruentata Veeeill, 1899. 



Adinioides cruentata Veeeill, 1899. 



These specimens are all identical with those I described from 

 the "Albatross" collection (1893) as Condyladis cruentata. They are, 

 however, in somewhat better condition and are accompanied by 

 notes of the coloration which dispel all doubts as to their identity 

 with the forms described by Dana (1846) as Adinia cruentata 

 Couthouy. This is a matter of importance, since Caelgren (1899) has 

 recently described a Bunodes {B. odoradiatus) from the Straits of 

 Magellan which, in its external form and coloration closely resembles 

 Dana's description, indeed, the figure which Carlgeen gives of his 

 Bunodes might readily be mistaken for a representation of an ex- 

 panded A. cruentata. Of course it is quite possible that Dana may have 

 confused individuals of the two species, but since in the description 

 he States the number of the tentacles to be forty-six while Cael-
