POLYNOIDAE 53 



St. WS 93. 9. iv. 27. 7 miles S 80° W of Beaver Island, West Falkland Island. From 

 51° 51' 00" S, 61° 30' 00" W to 51° 54' 00" S, 61° 30' 00" W. 133-130 m. Gear OTC. Bottom: 

 grey sand. Twenty-three specimens. 



St. WS 97. 18. iv. 27. 49° 00' 30" S, 61° 58' 00" W. From 49° 00' 00" S, 62° 00' 00" W to 

 49° oi' 00" S, 61° 56' 00" W. 146-145 m. Gear OTC. Bottom: sand, gravel and stones. Five 

 specimens, associated with an Alcyonarian. 



Remarks. There is much variation in the arrangement of the pigment. The longi- 

 tudinal dorsal stripe and the transverse markings may be both present or both absent, or 

 one may be present and the other absent. In some specimens there is a series of dark 

 brown markings on the ventral surface just below the neuropods. In a few examples 

 the ventral surface is a deep purple. 



The elytra are smooth except for a small patch of minute tubercles : the dorsal bristles 

 are smooth or very lightly striated: the ventral bristles are unidentate and expanded 

 towards the tip. Bergstrom has made a careful study of the variation in the arrangement 

 of the elytra in this species.

St. 51. 4. V. 26. Off 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. Two specimens. 



St. 181. 12. iii. 27. Schollaert Channel, Palmer Archipelago. 64° 20' 00" S, 63° 01' 00" W. 

 160-335 m. Gear OTL. Bottom: mud. One specimen. 



St. WS 73. 6. iii. 27. 51° 01' 00" S, 58° 54' 00" W. From 51° 02' 00" S, 58° 55' 00" W to 

 51° 00' 00" S, 58° 53' 00" W. 121-130 m. Gear OTC. Bottom: fine dark sand. Three specimens. 



St. WS 79. 13. iii. 27. 51° 01' 30" S, 64° 59' 30" W. From 51° 00' 00" S, 65° 00' 00" W to 

 51° 03' 00" S, 64° 59' 00" W. 132-131 m. Gear OTC. Bottom: fine dark sand. One specimen. 



St. WS 80. 14. iii. 27. 50° 57' 00" S, 63° 37' 30" W. From 50° 58' 00" S, 63" 39' 00" W to 

 50° 55' 30" S, 63° 36' 00" W. 152-156 m. Gear OTC. Bottom: fine dark sand. One specimen. 



St. WS 81. 19. iii. 27. 8 miles N 11° W of North Island, West Falkland Island. From 

 51° 30' 00" S, 61° 15' 00" W to 51° 30' 30" S, 6r° 10' 00" W. 81-82 m. Gear OTC. Bottom: 

 sand. One specimen. 



Remarks. All the specimens occur north of 52°, except the example from the Palmer 

 Archipelago, which is doubtfully attributable to this species. This specimen has the 

 scales and body coloured chestnut brown. The structure of the foot is typical, except 

 that there is a large bundle of abundant dorsal bristles instead of the usual few. The 

 dorsal cirri are very long, the tips of the ventral chaetae reaching only to about half 

 their length. There are only about 12 chaetigers behind the last pair of elytrophores. 

 The bristles are typical.
