Cuticle at the head end of body markedly widened (lateral membranes?); this gradually disappears posteriorly. Male mm. long by 400/x wide. Esophagus 1, tail 1/21 of total length. Gubernaculum present, three sided. Preanal sucker very narrow and elongate, slit-like. Nine pairs of caudal papillae. Figs. 181-184.—181. Subulura reclinata. Male tail. After Barreto, 1918. 182, Subulura recurvata. Male tail. After Linstow, 1901. 183, Subulura rima. Male tail. After Linstow, 1906. 184, Subulura rimula. Male tail. After Linstow, 1903 (fig. 183), of which 4 are preanal (the first pair near the sucker, thus far removed from the other 3 which are near the cloacal aperture) and 5 postanal. The right spicule 840/i long, the left 700/u, long. Female mm. long by 430^ wide. Esophagus 1/5, tail 1 of total length. Vulva slightly anterior to middle of body, dividing it in ratio of 51: 53. Eggs immature in specimen described. Life history.—Unknown; probably similar to that of Ascaridia galli (p. 82). Distribution.—Europe (Germany (Zoological Museum Koenigs- berg)). Baylis suggests that Subulura rima is a synonym of S. suctoria but as the descriptions of the two species are not comparable on certain points and as the number of caudal papillae and the spicule lengths differ, the present writer prefers to keep S. rima as a distinct Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States National Museum; S
