with four irregular rows of papillae. Parapodia 

 of setigers 1-8 (Figure llr) without papillae 

 medial to notosetae but with elongated post- 

 setal lamellae in notopodia and shorter but 

 similar lamellae in neuropodia Setiger 9 with 

 subequal lamellae, bearing bilimbate setae simi- 

 lar to those of setigers 1-8 (Figure lit). Ab- 

 domen with postsetal lamellae of both rami 

 rather small and expanded distally (Figure 

 lis). Relatively large papillae medial to hook- 

 rows both dorsal ly and ventral ly. Individual 

 hooded hooks with only one large denticle above 

 main fang (Figure llu, v). 



Remarks. — As noted by Jones (1963: 25) 

 this species is close to M. loiigiconti^ Johnson. 

 It may be distinguished by the absence of medial 

 papillae above the thoracic notosetae and the 

 possession of larger medial papillae on abdomi- 

 nal segments. Dr. Jones informs me that these 

 specimens from Beaufort appear to be the same 

 as specimens from Sapelo Island, Ga., and 

 Port Aransas, Tex. 



Records. — Off Beaufort in 10 m (*). This is a 

 new record for the United States.

15 mm. They were obviously different from the 

 other species recorded here and for this reason 

 the characters are summarized below. 



Description. — No color markings. Prosto- 

 mium (Figure llw) almost as broad as long 

 with distinct anterolateral angles. Anterior 

 parapodia (Figure llx) with medial papillae 

 above notosetae and postsetal lamellae of both 

 rami flattened and ligulate. Setiger 9 with 

 postsetal lamellae only, and with bilimbate 

 capillaries similar to those of setigers 1-8. 

 Abdominal parapodia (Figure lly) with broad 

 postsetal lamellae in both rami and papillae 

 medial to rows of hooks both dorsal ly and 

 ventrally. Individual hooks (Figure llz) with 

 two denticles side by side above main fang. 



Remarks. — This species is allied to both M. 

 filiforniis Wilson and M. aniuita Wesenberg- 

 Lund. A specimen of M. filifortnis, which Dr. 

 Wilson kindly sent to me, had much narrower 

 parapodial lamellae on the thorax. Possibly 

 these North Carolina specimens are closer to 

 M. cornutn but more material is required to 

 confirm the record.

FAMILY POECILOCHAETIDAE 



Poecilochaetus sp. 



Ri marks. — Only two anterior fragments were 

 obtained. They were obviously juveniles, the 

 larger measuring 4 mm for 22 segments. Final 

 identification is impossible, since the posterioi' 

 segments with their specialized setae are miss- 

 ing. However, the other characters agree with 

 P. serpens. The dorsum is smooth, not papillose, 

 though one specimen has a chitinized projection 

 on segment 9, rather like that described by 

 Hartman (1939) for /'. jolinso)ii. The nuchal 

 organ has three free lobes with fuzzy edges. 



and it is difficult to be certain whether the ends 

 are broken. The middle lobe reaches the pos- 

 terior margin of setiger 2 and the lateral lobes 

 are only slightly longer than broad. As u.sual 

 in the genus there are curved spines in the 

 iu'un)])odia of setigers 2 and 3 and long, flask- 

 shaped parapodial lobes with knobbed ends on 

 setigers 7 to 13. Plumose setae appear among 

 the capillaries on setiger 20. The smooth dor- 

 sum excludes P. fiilgoris and \hv thi'ee-lobed 

 nuchal organ suggests P. scrjx ns.
