Scoloplos (Leodamas) cirratus (Ehlers) 1897 



Aricia cirrata Ehlers, 1897, pp. 94-95, pi. 6, figs. 148, 149. 

 Scoloplos {Leodamas) cirratus Hartman, 1953, p. 38. 



Branchiae are present from the sixth setigerous segment to the end; 

 they are simple. The thorax consists of 27 to 31 segments. A subpodial 

 lobe resembling a ventral cirrus is present from segment 20-25, or from 

 about the sixth last thoracic segment, and continues through 18 anterior 

 abdominal segments. The last six thoracic neuropodia have a podial lobe 

 at the midlength of the setigerous ridge. 



Distribution. — Scoloplos (Leodamas) cirratus is known only from 

 the vicinity of the Falkland Islands off southern South America, in 

 shallow depths to 62 fathoms. 



Scoloplos (Leodamas) johnstonei (Day) 1934 



Scoloplos johnstonei Day, 1934, pp. 58-60, fig. 11. 



This species is here referred to the subgenus Leodamas because 

 branchiae are present from the sixth setigerous segment ; the presence 

 of projecting acicula from abdominal neuropodia is not established but 

 in other respects the species agrees with those of this subgenus. The 

 prostomium is acutely pointed and longer than wide. Thoracic neuro- 

 podia have three rows of uncini that are distally curved and smooth. 

 Thoracic parapodia have no podial or subpodial lobes and thus agree 

 with those of S. (L.) ohlini (Ehlers) with which johnstonei may have 

 its nearest affinities. 



Distribution. — Scoloplos {Leodamas) johnstonei is recorded only 

 from South Africa. 



Scoloplos (Leodamas) tribulosus (Ehlers) 1897 



Aricia tribulosa Ehlers, 1897, pp. 91-94, pi. 6, figs. 141-147. 

 Scoloplos tribulosus Eisig, 1914, p. 408; Fauvel, 1941, p. 286. 



This species is here referred to the subgenus Leodamas because the 

 branchiae are first present from the fifth to seventh setigerous segments; 

 the thorax consists of 25 to 28 segments. Subpodial lobes are absent. 



Distribution. — Scoloplos (Leodamas) tribulosus is known from 

 southern South America in intertidal zones.
