Dt'scriptioii. — Body about 25 mm long for 

 120 segment.s. Pro.stomium bluntly conical with 

 a short median antenna. Branchiae from setiger 

 5 to 20-25. Postsetal lobes of notopodia well 

 developed on anterior segments, short on middle 

 segments but long on terminal segments. A 

 heavy spine among notosetae from setiger 13; 

 each spine (Figure 13c) short, bluntly jjointed 

 with a fine subterminal filament. No .specialized 

 neurosetae. 



Rr /narks. — CirropIiorNs aricuhttiis Hartman 

 from deep water off southern California and off 

 Dutch Guinea is very similar but the heavy 

 notopodial spines are not reported to have a 

 -subterminal filament. 



Records.— Off Beaufort in 20 m {*).

Aricidea cerruti Laubier, 1967; 102, Fig. 1. 



Re»ia)'ks. — The specialized notosetae of pos- 

 terior segments are sigmoid hooks with spioni- 

 form hoods (Figure 13b). Pettibone's Figure 

 80 e does not show this but the shape is well 

 illustrated by Laubier, Hartman, and Day. Lau- 

 bier has also shown that the Mediterranean 

 specimens, doubtfully assigned by Cerruti (1909) 

 to Scolecolepis ? jeffreysii Mcintosh from Green- 

 land, are, in fact, distinct. 



Records. — Off Beaufort in 20 m (*). 



Distribution. — North Atlantic from Ireland 

 and the Gulf of St. Lawrence to Ma.s.sachusetts; 



Mediterranean and Black Sea; 

 western Canada; in 1-2,000 m.

Remarks. — This species is characterized by 

 the special neurosetae of posterior segments 

 (Figure 13a) which are unidentate with a long 

 hood on the conve.x side of the apex. 



Records.— Off Beaufort in 20-160 m (*). This
