English: Illustration from Report on the Radiolaria collected by Challenger during the years 1873-1876. Part III. Original description follows: Plate 122. Cœlographida. Diam. Fig. 1. Cœlotholus octonus, n. sp., × 30 The entire bivalved shell, seen obliquely from the dorsal and somewhat from the right side, enveloped by the yellowish calymma. Fig. 2. Cœlotholus octonus, n. sp., × 100 One valve of the shell (h) with its large galea and the origin of the three styles. The base of the two lateral styles (g1, g2) is connected by two latticed lateral frenula (b1, b2) with the mouth (m)

Cœlotholus octonus, n. sp., × 30 The entire bivalved shell, seen obliquely from the dorsal and somewhat from the right side, enveloped by the yellowish calymma. Fig. 2. Cœlotholus octonus, n. sp., × 100 One valve of the shell (h) with its large galea and the origin of the three styles. The base of the two lateral styles (g1, g2) is connected by two latticed lateral frenula (b1, b2) with the mouth (m) of the rhinocanna (t). The odd style (g3) is free. Fig. 3. Cœlothauma duodenum, n. sp., × 20 The entire shell, seen from the dorsal side. The long styles are enveloped by the yellowish calymma. Fig. 4. Cœlothauma duodenum, n. sp., × 80 One valve of the shell (h), seen from the apical side; t, rhinocanna; m, its mouth; b1, b2, the two lateral frenula; g1, g2, the two paired styles; g3, the odd style. Fig. 5. Cœlothauma duodenum, n. sp., × 80 One valve of the shell, seen in profile. Characters as in fig. 4. Fig. 6. Cœlothamnus bivalvis, n. sp., × 30 The entire shell, enveloped by the yellowish calymma, seen from the left side; between the two valves is the central capsule, with nucleus and astropyle. Fig. 7. Cœlothamnus bivalvis, n. sp., × 100 A single lateral anchor-pencil. Fig. 8. Cœlothamnus bivalvis, n. sp., × 200 Distal end of a style, with its anchor-pencils. Fig. 9. Cœlothamnus bivalvis, n. sp., × 400 A single anchor-thread, with its quadridentate terminal spathilla. . 1887 66 Radiolaria (Challenger) Plate 122
