Paraspirura mabuyae. Frontal view of head. base two pairs of papillae of which the inner are minute, the outer fairly large and prominent; in addition, somewhat anterior to the papillae in the median field of each lip is a relatively large circular amphid. Cuticular elevations in the form of narrow membranous shields (? interlabia) form a bridge between the lips dorsally and ven- trally. On the internal face of each lip near its apex is a minute tooth- like projection, and behind this is a serrated edge that recalls the denticular ridges of some species of Abreviata. From the frontal view (Fig. 1) the oral aperture is seen to be dorso-ventrally elongated with a pronounced constriction in the middle. The lips are not superficially lobed though lateral and dorsal views of the head (Figs. 2 and 3) show grooves and cuticular flanges on their internal faces. Buccal cavity cylindrical, 45 to 55 n long and about 30 fj. wide, with delicate, lightly cuticularized 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 Harvard University.
