Description. — Body purple when fresh, up to 

 20 mm long, swollen anteriorly, slender pos- 

 teriorly. Tentacular lobe large, folded, often 

 trefoil-shaped, bearing numerous short tentacles. 

 No eyespots. No branchiae. Notosetae from 

 segment 3, and setae sometimes retracted into 

 notopodial lobes. First 10-11 setigers with 

 small smooth-winged capillaries (Figure 16d) 

 followed by 5 achaetous segments at junction 

 of thorax and abdomen; finally about 30 ab- 

 dominal .'segments bearing a few blunt acicular 

 setae (F^igure 16e) in notopodia. Neuropodia 

 and neurosetae entirely absent. Ventrum of 

 thorax (Figure 16f) swollen, glandular and 

 tessellated, with a median groove concealing 

 a row of nine poorly defined ventral pads. 



Records. — Common off Beaufort in 80-200 m 

 (21,*). 



Distributioji. — Arctic; Norway; New Eng- 

 land; Mediterranean: South Africa: .Japan; 50- 

 500 m.

 Fig. 246, text Fig. 98. - Kirkegaard. 1959: 

 89, Fig. 22. 



Description. — Generally similar to A. t rilo- 

 bata de.scribed above, with following exceptions: 

 Body pale not purple; 11-13 thoracic segments 

 with notosetae, not 10-11; notosetae of two 

 types, longer ones with smooth narrow wings 

 resembling those of A. trilobata and shorter 

 ones (Figure 16g) with ccmipletely spinuloso 

 blades. 



Remarks. — All 1 1 specimens collected were 

 broken between the 9th and 11th setigerous 

 segments, and no abdominal segments with 

 acicular notosetae were obtained. 



Records. — Off Beaufort in 80-160 m (21, *). 

 This is a new record for the United States. 



Distributiou. — Ghana; ? South Africa; inter- 

 tidal.

only). 



Holotype. — USNM 43122; four paratypes, 

 USNM 43123. 



Deso-iptioii. — Body uniformly pale in alcohol. 

 30 mm long for 80 segments, swollen anteriorly 

 and constricted between setigers 10 and 15. 

 Tentacular lobe large, irregularly folded, roughly 

 trefoil-shaped, with numerous contractile ten- 

 tacles. Notosetae from segment 2 and present 

 on 33 segments in holotype (paratypes with 

 25, 27, 38, and 48 segments with notosetae). 

 Notopodia without terminal free lobes. Neuro- 

 setae from 7th setigerous segment. Mouth with 

 lower lip as a large ventral cushion. Ventral 

 surface of thorax from segment 2 to 10 with 

 glandular swellings. Ventral pads small and 

 sunken in a midventral groove. Large nephridial 

 papillae below notopodia of setigers 4, 5. and 

 6 and a doubtful one on .setiger 3. Five or six 

 pairs of large nephridia revealed by dissection. 

 Noto.setae of two types; four or five longer 

 capillaries with smooth blades (Figure 16o) and 

 three or four shoiler capillaries with plumose 

 blades (Figure 16p) formed by a series of over- 

 lapping cones on a slender axis. Neuropodial 

 uncini small and arranged in a single row. In- 

 dividual uncini (Figure 16m, n) with one large 

 tooth and an arc of 8-10 small teeth above main 

 fang; formula: MF: 1 : 8-10. Base of uncinus 

 .striated. 



Reniarl^s. — The type specimens were col- 

 lected off Beaufort in 20 m on .sand; Dr. Mc- 

 Closkey's specimens were collected off Beaufort 

 on coral in 18.3 m. The plumose .setae of P. 

 carol inoisis shows that it is related to P. phmio- 

 sus WoUebaok. P. uiedius Hessle, and P. coc- 

 ciuea Grube but it differs from them in the num- 

 ber of segments bearing notosetae, the .seg- 

 ment on which the first row of uncini occurs, 

 and in the shape of the uncini them.selves. 



Ricords. — On coral and sand in 18.3-20 m 

 off Beaufort (20, *).
