. Bulletin - United States National Museum. Science. POLYCHAETE WORMS, PART 1 261 prostomium and first segment enclosing a retractile globular papilla (not always visible). Parapodia with short rounded presetal lobe, with a slender digitiform postsetal process on the anterior parapodia (fig. GSh). The postsetal lobes rather prominent on about first 40 segments, gradually becoming smaller and reduced to a small papilla. The lobes contain a vascular loop (they were referred to as a 1-lobed branchia by Moore for Ninoe fusca); in the far posterior region, the short postsetal lobe is more conspicuo

Anterior parapodia with limbate capillary setae. Middle parapodia with some long-winged simple hooks (appear as worn or in- completely formed limbate capillaries). More posterior parapodia with short-winged simple hooks. Lower half of setae dark, distal half yellow. Acicula black. Proboscis with maxillae ii each with 3 large.
