<paragraph pageId="58" pageNumber="59">Two specimens (ZMA 1717), dried out. Longer, complete specimen (Fig. 20A) with introvert exposed, body wall breaking apart, 10 mm long, 3.3 mm wide. First three chaetigers with 10-12 bronze, subdistally expanded hooks (Fig. 20B). Ventro-caudal shield without sediment particles, longer than wide; anterior margins rounded, anterior depression shallow, lateral margins rounded (Fig. 20C); suture barely visible. Fan expanded beyond posterior corners, with median notch. Posterior region without branchiae, branchial plates not visible (Fig. 20D).</paragraph>

<paragraph pageId="58" pageNumber="59">The other specimen (MNHN Musorstrom 3-94) with introvert invaginated; body 8 mm long, 5.5 mm wide. Ventro-caudal shield reddish with barely defined ribs and sediment particles removable by brushing. Chaetal fascicles better developed laterally, 10 bundles per side, and 6 posterior fascicles feebly developed per side.Branchiae lost, branchial plates barely projected, with abundant sediment particles.</paragraph>

because of several features: 1) the shield does not have well developed ribs, nor concentric lines on the surface, and 2) one of the Leiden specimens has spatulate introvert hooks. However, because of the state of the specimens, their complete description and affinities must wait until additional material becomes available. It can be indicated, however, that because of their shield shape, they resemble
