FIGURE 2. Cirrodrilus japonicus (Pierantoni, 1912) A. Lateral view of a whole specimen, redrawn from Yamaguchi (1934: Fig. 7A), scale bar = 200 μm. B. Ventral view of peristomium showing four dorsal lip lobes, two pairs of lateral lobes and the ventral lip with a median emargination, a whole-mounted specimen from Teuri Is. (see Fig. 1, site No. 24), scale bar = 50 μm. C. Anterior view of the dorsal over ventral jaws in a whole-mounted specimen from Hamanaka (see Fig. 1, site No. 18), scale bar = 10 μm. D. Lateral view of segment 5 (left) with the spermatheca and male genitalia in segment 6 (right), a whole-mounted specimen from Esashi (see Fig. 1, site No. 21), scale bar = 50 μm. Legend: Stippled, spermathecal bulb; short transverse lines, spermathecal duct and muscular atrium; stippled discs, glandular atrium; longitudinal lines, muscular bursa. Vasa deferentia not shown. E, F. Dorsal (top) and ventral (bottom) jaws of C. japonicus from an anterior aspect showing variations of the small lateral teeth and ridges. E. A specimen from Obihiro (see Fig. 1, site No. 19). F. A specimen from Hamanaka (see Fig. 1, site No. 18), scale bar = 10 μm. G–I. Original figures from Pierantoni (1912: Tab. 5, Figs. 11, 12 & 13), redrawn. G. "Fig. 11—Regione cefalica di Stephanodrilus japonicus n. sp. x120" [head region of Stephanodrilus japonicus]. H. "Fig. 13—Mascella della stessa species, x1200" [jaws of the same species]. I. "Figure 12—Regione genitale della stessa. x500." [genital region]. Legend gives original abbreviations and, in square brackets, names in modern terminology: at, atrio [glandular atrium]; isp, imbuto spermarico [sperm funnel]; ov, ovario [ovary]; spd, spermadutto [sperm duct]; spt, spermateca [spermatheca]; te, testicolo [testis]; tp, tasco peniale [muscular bursa]. Additional features: msp, mature sperm; sps, sperm sac (grey).
