Description
Test free and of generally friable consistency. Hemispherical or subrectangular in overall shape and consisting of anastomosing branches and plate- shaped elements which delimit open spaces. Surface xenophyae form more or less firm I y cemented layer. Interior contains loose accumulations of xenophyae , between which s t e r- comare and xenophyae interweave. Occurrence : Northeast Atlantic, Indian Ocean, west and east Pacific, Antarctica ; bathymetric range 7 4 3-6 0 59 m. ro unded, somewhat flattened and up to 60 m m maximum diameter, consisting of anastomosing plate-like branches mostly about 5 mm wide . Open CLASS XENOPHYOPHORE spaces circular to oval and 2-10 mm wide . Internal xenophyae are planktonic foraminiferal tests ; surface layer consists of well-cemented , fine - grained calcareous material with scattered planktonic foraminiferal tests. Other species: R. labyrinthica Tendal , 1972 (Fig. 11 ); R. lame/lata Tendal , 1972 ; R. cretacea (Haeckel , 1889) ; R. maini Tendal & Lewis , 1978 ; R. antarctic Riemann & Gingele , 1993. Several undescribed species occur in the eastern Pacific . References: Tendal (1972) ; Ri ce et al. (1979); Tendal and Gooday (1982) ; Levin and Thomas (1988) ; Gooday and Tendal (1988) ; Gooday (1991 ) ; Riemann et al. (1993) . Specimens photographed on the seafloor off NW Africa at 4000 m bathymetric depth . Largest specimen about 5 em diameter.
