Station 4653 surface 1 specimen, pneumatophore and 3 cormidia. 



Although the single specimen was in very poor condition, the tentilla were 

 sufficiently well preserved to show the simple thread-like form characteristic 

 of R. eysenhardtii, well described and figured by Huxley for his specimen from the 

 Indian Ocean. The specimen differs in no way from the "Siboga" specimens 

 of this species described by Lens and Van Riemsdijk. 



R. eysenhardtii was previously known from various parts of the Tropical 

 Atlantic, from the Indian Ocean (Huxley, Haeckel), and from the Malaysian 

 region. Its occurrence in the Eastern Tropical Pacific shows that, like R. fili- 

 formis, it occurs throughout the warm regions of all oceans. 



Epibuliinae, nom. nov. 

 Epibulidae Haeckel, 1888. 



Only one genus, Epibulia, of this subfamily, is known. For the early history 

 of the name, see Haeckel ('88b, p. 334). One species, E. ritteriana Haeckel, 

 from the Indian Ocean, has been carefully described and beautifully figured. 

 Two others from the Pacific, E. (Rhizophysa) chamissonis Eysenhardt, the type, 

 and E. erythrophysa Brandt, are known, but from such incomplete accounts 

 that their relationship to Haeckel's form remains doubtful (p. 350). 



The genus is not represented in the "Albatross" collection. 



Bathphysinae Chun, 1897. 

 Bathyphysidae Bedot, :04; Lens and Van Riemsdijk, :08. 



Lens and Van Riemsdijk (:08) have reviewed the history of this little- 

 known group, and their own researches on the material of the "Siboga" expe- 

 dition have afforded detailed information as to the anatomy of three species.
