Deseriptii))!. — Body without color markings, 

 50-60 mm long. Prostomium (Figure 12h) sharply 

 conical. Thorax of 18-19 setigers with branchiae 

 from 10th setiger (or 8th in juveniles). Noto- 

 podial postsetal lobe well developed from setiger 

 1. Thoracic neuropodia as lateral ridges with 

 one large foot-papilla from setiger 3, two on 

 10th foot and three on 16th. Stomach-papillae 

 increasing from 1 below 16th foot to 14-18 at 

 junction of thorax and abdomen (Figure 12i). 

 Abdominal notopodia as chopper-shaped lobes 

 smaller than the branchiae. A well-developed 

 interramal cirrus (Figure 121). Abdominal neuro- 

 podia bilobed; several stomach-papillae below 

 first few abdominal neuropodia decreasing to 

 2 on setiger 26 (7th abdominal segment) and 

 thereafter flattened to form two lamellar expan- 

 sions at base of neuropodium. 



Thoracic notosetae as crenulate capillaries. 

 Abdominal notosetae with three or four forked 

 setae among capillaries. Thoracic neurosetae 

 in four or five vertical rows; an anterior row of 

 crenulate capillaries with blades broadened 

 basally, then two or three rows of hooks and a 

 posterior row of fine capillaries. Individual hooks 

 (Figure 12j) blunt and well serrated, with deli- 

 cate sheaths. Abdominal neurosetae with two 

 acicula, two or three fine crenulate capillaries, 

 and one or two long flail-setae (Figure 12k) with 

 serrated shafts and abruptly tapered tips. 



Remarks. — This species has been described 

 in some detail as the original description was 

 based on a specimen only 25 mm long and pre- 

 sumably a juvenile with branchiae from .setiger 

 8. It has been transferred to the genus Orhiiiia 

 since it possesses many stomach-i)ai)illae.

Descriptio)!. — Body up to 25 mm long for 105 

 segments with brown bars across thorax from 

 setiger 9 to 17 when fresh. Prostomium (Figure 

 12m) sharply pointed, longer than broad. Thorax 

 with 16-17 setigers and branchiae from setiger 

 13-14. Notopodia with postsetal lobes obvious 

 from setiger 1, slender anteriorly, longer and 

 stouter in abdomen but never as stout as the 

 branchiae. Thoracic neuropodia (Figure 12n) 

 as low lateral ridges with a single median foot- 

 papilla from setiger 4, increasing in length and 

 moving to a superior position towards end of 

 thorax. No stomach-papilla. Abdominal seg- 

 ments without interramal cirri. Abdominal neuro- 

 podia bilobed with inner lobe rather longer than 

 outer and base expanded to form a broad brown 

 unnotched lateral lamella. No ventral cirri. 



Notosetae of thorax and abdomen as crenu- 

 late capillaries, there being no forked setae. 

 Thoracic neurosetae in five vertical rows; an 

 anterior row of crenulate capillaries, then 

 three rows of hooks and finally a posterior row 

 of crenulate capillaries. Individual hooks (Figure 

 12o) almost straight, blunt and serrated, with 

 delicate guards. Abdominal neurosetae sup- 

 ported by one aciculum and include a few small 

 crenulate capillaries and one or two longer and 

 stouter flail-setae (Figure r2p). 



Remarks. — In accordance with the generic 

 revision described above, Scolaricia capeasis 

 becomes Scoloplos (Scoloplos) capoisis. The 

 specimens from North Carolina agree with the 

 holotype from South Africa apart from the fact 

 that the fresh specimens had well-marked brown 

 bars across posterior thoracic segments which 

 were not observed on the holotype. S. (S.) capeii- 

 sis is close to S. (S.) acineceps Chamberlin; but 

 it has fewer thoracic segments, the gills appear 

 more anteriorly, and there are no forked setae. 

 No brown bars were noted on S. (S.) acmeceps. 



Records. — Common off Beaufort in 40-200 m 

 (21, *). This is a new record for the United 

 States. 



Distribution. — South Africa in 86 m.
