Description
Test usually free , occasionally attached , hemispherical in overall shape and consisting either of numerous radiating tubes connected by side branches or of more irregular networks of tubes. Tube walls consist of firmly cemented xenophyae . Interior occupied by granellare and stercomare. Occurrence : North Atlantic, Southern Ocean , southwest Pacific , 740-4795 m. rounded and up to 38 mm in size . Tubes organized irregularly in central region , towards periphery they are more radial and anastomosing side branches form consecutive layers 1.3-2.5 mm apart . Tube diameter varies from 0.5 mm to 1.0 mm and wall thickness is about 0.13 mm . Xenophyae are fine sand grains and small planktonic foraminiferal tests . Each tube contains 3- 6 longitudinally running granellare strands and one thick, centrally located stercomare string . Other species : S. minute Pearcey , 1914; S. tasmanensis Lewis , 1966 , S. reticulata Gooday, 1996 , (Fig . 14) . A large , undescribed species has been photographed on the seafloor in the NE At lantic (Tendal and Gooday, 1981 , Fig 1. Gooday and Bett. unpubl.) . Refs. Brady (1883) ; Lewis (1966) ; Tendal (1972) ; Tendal and Lewis (1978) ; Tendal and Gooday (1981 ); Levin (1991 ). Lectotype (after Tendal , 1972, new print) .
