TETRAXONIDA 



deep cloaca with a number of smaller oscules scattered over surface generally ; 



firm and slightly compressible; skeleton a dense or 



feebly knit reticulation of styli, often showing strongly 



marked primary fibres which project slightly beyond 



ectosome as surface brushes; auxiliary spicules, found 



chiefly associated with dermal brushes, slender sub- 



tylostyli; microscleres toxa and chelae; styli of main 



skeleton slightly curved, o-36-o-5i by o-oi3-o-028 mm. ; 



auxiliary subtylostyli, straight with crown of spines at 



basal end and with distal end pointed or, occasionally, 



blunted and spined, o-z^-o-^z by o-oo6 mm.; toxa of 



varying size, smaller forms slender and strongly bent, 



larger stout and strongly spined at ends, o-03-o-54 mm. 



long; isochelae palmatae, o-oo9-o-oi5 mm. chord. 



Remarks. The species is characterized by its external 

 form and by the character of the microscleres. In 

 many respects it resembles Artemisina dianae, Topsent, 

 and forms, in fact, a connecting Hnk between the two 

 genera Ophlitospoiigia and Artemisina, so that it becomes 

 a matter of doubt whether these two genera can be 

 maintained. 



Genus Artemisina, Vosmaer 

 Artemisina apollinis (Ridley and Dendy). 

 (For synonymy see Burton, 1929, p. 431.) 

 Occurrence. St. 42: South Georgia, 120-204 m.

Artemisina plumosa, Hentschel. 



A. plumosa, Hentschel, 1914, p. 70, pi. iv, fig. 5, pi. vi, fig. i ; A. plumosa, var. lipochela, id., 

 loc. cit., p. 72; A. strongyla, id., loc. cit., p. 72, pi. vi, fig. 2. 



Occurrence. St. WS 109: Falkland Islands, 145 m. 



Remarks. An irregularly branching and anastomosing specimen having the general 

 external characters of A. plumosa, var. lipochela, and a similar skeleton except that 

 microscleres appear to be quite absent. 



Distribution. Wilhelm Land.
