SYLLIDAE 97 



Trypanosyllis gemmulifera, Augener. 



Augener, 1918, p. 278, pi. v, figs. 99-101, text-fig. 27. 



St. I. 16. xi. 25. Clarence Bay, Ascension Island. 7° 55' 15" S, 14° z^'oo" W. 16-27 "^- Gear 

 NRM. Bottom: coralline sand and shell. One specimen. 



Remarks. The single example of this species from Ascension Island corresponds in 

 detail to Augener's description. The long cirri, the bidentate chaetal blades, and the 

 brown double banding on the back are distinctive. I can find no trace of buds. 



Genus Autolytus, Grube 

 Autolytus charcoti, Gravier. 



Gravier, 1907, p. 7, pi- i, figs. 1-2. 



St. 45. 6. iv. 26. 2-7 miles S 85" E of Jason Light, South Georgia. 238-270 m. Gear OTL. 

 Bottom: grey mud. One specimen. 



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

 126 m. Gear DLH and NRL. Bottom : stones, mud and rock. " Found inside a colony of Cephalo- 

 discus nigrescms, living in the tubules of the polypides." One specimen. 



St. MS 14. 17. ii. 25. From 1-5 miles SE x S to 1-5 miles S J W of Sappho Point, East 

 Cumberland Bay, South Georgia. 190 110 m. Gear DS. One specimen. 



Remarks. This species is characterised by the very distinct nuchal organs and the 

 long slender tentacular and dorsal cirri. 



In the specimen from St. 190, the pedal lobe is more thickened on top above the 

 bristles than as shown by Gravier, but less than in Mcintosh's A. maclearamis. 



Autolytus gibber, Ehlers. 



Ehlers, 1897, p. 55, pi. iii, figs. 71 and 72. 



St. 141. 29. xii. 26. East Cumberland Bay, South Georgia. 200 yards from shore under Mount 

 Duse. 17-27 m. Gear BTS. Bottom: mud. Three specimens. 



St. 170. 23. ii. 27. Off Cape Bowles, Clarence Island, 61° 25' 30" S, 53° 46' 00" W. 342 m. 

 Gear DLH. Bottom: rock. One specimen. 



Remarks. The examples of this species are all in rather poor condition. A. gibber is 

 a more massive species than A. charcoti, the tentacles and tentacular cirri are thicker 

 and shorter and the nuchal organs very much less distinct. I cannot distinguish with 

 certainty the flap or gibbosity behind the head described by Ehlers. In the example 

 from St. 170, the transverse lines of pigment dots are faintly visible across the back, 

 but not on the cirri. 



Autolytus simplex, Ehlers. 



Ehlers, 1901, p. 97, pi. x, figs. 5-8. 

 Pratt, 1901, p. 2. 

 Fauvel, 1916, p. 430. 



St. 53. 12. V. 26. Port Stanley, East Falkland Island. Hulk of " Great Britain." 0-2 m. Gear 

 RM. Twelve specimens.
