Hinge plate with a nar- row, elongate, amphidetic internal liga- ment; posterior hinge plate slightly shorter and straighter than the anterior; three or four chevron-shaped teeth present in the anterior and posterior tooth series (Fig. 10). Neither inhalent or exhalent apertures present nor an anterior mantle sense organ. Adductor muscles equal in size. Few hypo- branchial gland cells present in the epi- thelia of the ctenidial axes. No specialized mantle glands present. Gills set transversely across the posterior part of the mantle cavity, anterior to the posterior adductor; six pairs of fingerlike gill plates, each pair oppositely attached to axis; posterior axial extension present as in Pristiglorna. Palps large, not rectangular, but somewhat fan- shaped, each with 12 internal ridges, and extend to the posterior edge of foot. Mouth set slightly behind the anterior adductor muscle. Stomach moderately large with 3 sorting ridges and 2 ducts to the digestive glands; style sac moderately large with a combined midgut from which the hindgut passes dorsally. Subsequently the hindgut is arranged so that there is 1 loop on left Sh
