Holotype (USNM 1661244) (Figs. 29A–C, 30A, E) with 100 setigers, 12.1 mm long, 0.4 mm wide; largest specimen (USNM 1661295) with 151 setigers, 21 mm long, 0.5 mm wide across anterior setigers; another large specimen (USNM 1661267) with 102 setigers, 16. 5 mm long and 0.45 mm wide; a 49-setiger specimen (USNM 1661274) 5.8 mm long, 0.18 mm wide (Fig. 30B); a 26-setiger juvenile 2.4 mm long and 0.09 mm wide (Fig. 30C) and an 18-setiger juvenile 1.46 mm long and 0.08 mm wide (USNM 1661322) (Fig. 30D). Body elongate, cylindrical in cross section; anterior 15–20 setigers of adults short, crowded, about 7–8 times wider than long (Fig. 30A), then individual segments increasing in length in middle body, becoming moniliform posteriorly (Fig. 30B), but with farthest posterior segments again narrowing to pygidium (Fig. 30B–E). Juveniles and smaller adults with middle and posterior segments moniliform (Fig. 30C–D). Dorsal and ventral grooves not apparent. Color in alcohol light tan; larger specimens, including holotype, with clusters of black pigment spots on lateral margins of last peristomial ring (Figs. 29C, 30G). Pre-setiger region elongate, narrow, as long as first ten setigers in larger specimens (Figs. 29A–C, 30A). Prostomium conical, tapering to narrow rounded tip; entire prostomium turned upward in some specimens (Figs. 29A, 30A–B); eyespots absent; nuchal organs curved notches on posterior lateral margin, appearing as pigmented spots in some juveniles. Peristomium long, divided into three distinct rings with grooves apparent laterally (Fig. 29A–B); rings not complete dorsally; first ring merged dorsally with posterior margin of prostomium and ventrally surrounding oral opening from which bulbous pharynx or proboscis emerges (Figs. 29B–C, 30F–G). Some specimens with first peristomial ring dorsally elevated producing rounded crest, but consistent dorsal crest not present in this species. Ventrally, first peristomial ring separated from merged second and third ring by deep groove (Fig. 29B); second and third rings only separated laterally, but distinctly separated from setiger 1 by a deep groove (Fig. 29C). Dorsal tentacles arising from posterior margin of peristomium with first pair of branchiae lateral to tentacles (Fig. 29A). Second pair of branchiae on setiger 1 dorsal to notosetae; branchiae in similar location on following segments. Branchiae mostly missing, but when present each long and thin, occurring along most of body (Figs. 29A–B, 30A, D). Parapodia of anterior and middle segments reduced to low ridges or mounds from which setae arise; segments moniliform in posterior and more anteriorly in smaller specimens with parapodia dorsolateral with noto- and notopodia close to one another (Fig. 31A). Parapodial cinctures not present.Anterior setae all long capillaries numbering about 12–15 per fascicle in largest specimens and usually including long natatory-like setae in notopodia of anterior and middle segments; these not associated with sexual maturity. Neuropodial spines from middle body segments in juveniles and specimens with fewer than 75 setigers; holotype and larger specimens with neuropodial spines from posterior quarter of body, setiger 73 of 100 in holotype. Neuropodial spines numbering 1–3 in juveniles, increasing to 7–8 per fascicle in largest specimens. Neuropodial spines narrow, with rounded tip, distinctly curved sigmoidally in ventral-most spines, becoming straighter and more elongate in dorsal part of fascicle (Figs. 29D–F, 31C). Notosetae of posterior setigers mostly capillaries (Fig. 31B), with spines only present in a few pre-pygidial setigers in largest specimens, these numbering no more that 1–2 per fascicle; each straight, with sharply pointed tip. Maximal number of spines observed in largest specimens 8–10 on a side; most specimens with no more than 4–7 spines on a side. Body terminating in short pygidium bearing a semicircular disk ventral to the anal opening (Fig. 30E). Methyl green staining. A distinctive MG staining pattern is evident on the pre-setiger region (Figs. 30 F–G) where the prostomium and peristomium stain prominently with dorsolateral unstained patches; the second and third peristomial rings typically stain dark blue; the proboscis when extended and posterior lips of the mouth do not stain (Fig. 30F–G). In larger specimens, the parapodia of 3–4 anterior setigers also stain to varying degrees. The rest of the body de-stains rapidly with no pattern. Remarks. Chaetozone paucispinosa n. sp. is a widespread lower continental slope species along the US Atlantic coast, with numerous specimens available for study including juveniles and sexually mature adults. Due to the large number of specimens that were collected, it was possible to document the considerable variation in their overall appearance with growth. Juveniles initially have moniliform segments along most of their length; after about 50 setigers are developed, the first third of the body has crowded segments, with moniliform segments retained in the posterior two-thirds. The largest specimens only have moniliform segments in the last 15 or so segments. Most specimens, large or small, have an expanded oral opening from which a partially protruding pharynx is typically observed (Figs. 29A–C, 30B–D, F–G). In lateral view the everted pharynx is easily visible and provides a superficial clue relative to the identification of this species. In many of the larger specimens, the prostomium is turned up, or somewhat directed dorsally, best seen in lateral view (Figs. 29C, 30B). The acicular spines are generally narrow with the smaller spines being curved and the longer ones having straighter shafts. The largest specimens also have black pigment spots located ventrolateral on the last peristomial ring (Figs. 29C, 30G).
