FIGURE 19. Protula cf. palliata from the Great Bitter Lake (B&T-C-Pol 27- HUJ-Poly-1567), ca. 87 chaetigers, body ~27 mm length + ~5.6 mm branchia = total length ~32.6 mm; width, ~2.2 mm. A—Branchial lobe, inside view; arrow designates dorsal ovoid mouth palp; 19+?few more radioles, B—Enlargement of base of lobe to show the palp, C— Branchial lobe, outside view, D—Radiole; arrows designate white blotches; note the tip appears less filiform than that in Fig. 16A (?likely due to preservation), E—Low interradiolar membrane of branchial lobe at base of branchial lobe (arrows), F—Body, thorax of 7 chaetigers and abdomen of ca. 80 chaetigers (counted from photograph), 3/4 view dorsal side up; note dorsal pygidial glandular pad, G—Thoracic chaetae of 7th (last) chaetiger, Apomatus chaetae not present,. H, I—Abdominal chaetae, sickle-shaped: H—SEM micrograph, 2,400 x, I. Microscopic view with oil immersion. Scales: C, D—1 mm, F—5 mm; G—100 µm.
