PLATE 9, FIGURES 48–54. G. XINJIANGIANA. SEM. Figs 49–51, external views. Fig. 49. Headpole, with striae composed of double rows of areolae and distal raphe end bending slightly onto the mantle. Fig. 50. Central area with proximal raphe ends dilated and striae with double rows of areolae, but terminating in a single areola. Fig. 51. Footpole, with apical pore field bisects by distal raphe end. Porelli of pore field in rows of two, appearing morphologically similar to areolae. Figs 48, 52–54, External views. Fig. 48. Entire valve view, with central nodule, helictoglossae and pseudosepta prominent. Fig. 52. Headpole, showing pseuoseptum and helictoglossa. Fig. 53. Central area, with small, elevated central nodule having proximal raphe ends recurved slightly, and striae tapering from 2 rows to 1 row of areolae. Fig. 54. Footpole, with helictoglossa aligned straight with the raphe and thin interstriae evident at the apical pore field.
