Genus Syllis, Savigny 



Syllis prolixa, Ehlers. 



Ehlers, 1901, p. 92, pi. ix, figs. 1-7. 



Syllis longifilis, Ehlers, 1901, p. 95, pi. x, fig. 3. 



St. 45. 6. iv. 26. 27 miles S 85° E of Jason Light, South Georgia. 238-270 m. Gear OTL. 

 Bottom: grey mud. One specimen. .q, 



St. 51. 4. V. 26. Ofl^ Eddystone Rock, East Falkland Island. From 7 miles 

 N 50° E to 7-6 miles N 63° E of Eddystone Rock. io5-ii5m. Gear OTL. 

 Bottom: fine sand. One specimen. 



St. 58. 19. V. 26. Port Stanley, East Falkland Island. 1-2 m. Gear RM. 

 One specimen. 



Remarks. I have assigned these two specimens to S. prolixa, because 

 of their long multi-articulate dorsal cirri and the absence of a second 

 tooth to the chaetal blades. About the latter character it is very 

 difficult to be certain with the material at my disposal, but I am unable 

 definitely to find a subapical tooth. In the example from St. 58, traces 

 of a transverse brown banding can be discerned. The bristles (Fig. 32) 

 closely resemble that figured by Ehlers for S. longifilis. S. prolixa and 

 S. longifilis seem to be growth stages of the same species, and the former has priority.

Syllis brachychaeta, Schmarda, 



Augener, 1918, p. 247, pi. iv, figs. 83-85; pi. v, fig. 98, text-fig. 20; and 1924 a, p. 358. 



St. 4. 30. i. 26. Tristan da Cunha. 36° 55' 00" S, 12° 12' 00" W. 40-46 m. Gear DL. Bottom: 

 stones. " From debris of stones with incrustations." Four specimens. 



St. 190. 24. iii. 27. Bismarck Strait, Palmer Archipelago. 64° 56' 00" S, 65° 35'oo"W. 93- 

 126 m. Gear DLH and NRL. Bottom: stones, mud and rock. " Found inside a colony of Ce/)/;«/o- 

 discus nigrescens, living in the tubules of the polypides." Eight specimens. 



Saldanha Bay beach. Cape of Good Hope. One specimen. 



Remarks. Augener has studied this species at great length, and has come to the 

 conclusion that Syllis closterobranchia, Schmarda, and S. hyalina, Grube, are synonyms 

 of S. brachychaeta . I have not sufficient material to form an opinion of my own on this 

 matter, so I accept Augener 's conclusions. 



This species is easily recognisable by its short pauci-articulate spindle-shaped dorsal 

 cirri. 



Syllis brachycola, Ehlers.

 at 115 m. Gear DLH. Two specimens.
