152 DISCOVERY REPORTS 



In the anterior region the bristles of both bundles are similar; they are very delicate, 

 unbordered capillaries (Fig. 58, b) and in the preparations the ends are often twisted. 

 Between the 20th and 25th feet a shorter and much stouter hook (Fig. 58, c) appears in 

 the ventral bristle bundle: these hooks increase in number posteriorly; until towards 

 the end of the body they are about six in number with a few capillaries amongst them. 



In the hinder region I can see no dorsal cirrus, and the notopodium is represented 

 by a few fine capillary bristles. The specimens are too imperfect to make out a pygidium. 



Mesnil and Caullery write " Du 30*^ au 40<' setigere, il existe un mamelon transversal 

 tres net en avant des soies." I take this to refer to the genital papillae (Fig. 58, d) 

 which, from about the 30th to the 60th chaetiger, lie a little below and in front of the feet. 



Remarks. These specimens agree in the main with Mesnil's account of Tauber's 

 species, but more material both from the north and the south is required before the 

 identity of the forms from the two hemispheres can be established with certainty. 



Family CHAETOPTERIDAE 



Chaetopterus variopedatus (Renier). 



Fauvel, 1927, p. 77, fig. 26 an. • 



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

 three large tubes.

 8° 38' 15" S, 13° 13' 00" E. 64-65 m. Gear OTL. Bottom: grey mud. 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. Two specimens. 



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, 61° 10' 00" W. 81-82 m. Gear OTC. Bottom: sand. 

 Eight specimens. 



St. WS 88. 6. iv. 27. 54° 00' 00" S, 64° 57' 30" W. From 54° 00' 00" S, 65° 00' 00" W to 

 54° 00' 00" S, 64° 55' 00" W. 118 m. Gear OTC. Bottom: sand, shell and stones. One specimen. 



St. WS 128. 10. vi. 27. West side of Gough Island, inshore. 40° 19' 00" S, 10° 04' 00" W. 

 120-90 m. Gear DLH. Several fragments of tubes. 



Remarks. The greater part of these specimens consists of fragments only. Port 

 Stanley, East Falkland Island, however, yielded two intact specimens, the largest of 

 which has 10 thoracic chaetigers, 5 median chaetigers and 28 posterior chaetigers. In 

 all the specimens in which it is possible to make a count, there are 9 to 10 thoracic and 

 5 middle chaetigers. I cannot accept Augener's suggestion (1918, p. 458) that the 

 Ch. variopedatus, Ehlers, from Southern America should be regarded as a distinct 

 species, Ch. antarcticus, Kinberg.
