prolonged at its middle, and a ventral cirrus again much smaller than 

 that in median parapodia. Neurosetae are composite spinigers in fan- 

 shaped fascicles. 



The proboscis has a distal circlet of 18 or 20 soft papillae. Macro- 

 gnaths have 4 large clawlike teeth. Micrognaths form a complete circle, 

 with about 23 pieces in the dorsal and 16 in the ventral arc. Chevrons 

 number 26 pairs. The proboscidial organs are conical with blunt apex 

 and a minute pore nearly halfway down one side.

An ovigerous individual with 182 segments measures 140 mm long 

 and 10-11 mm wide with parapodia; the everted proboscis measures an 

 additional 40 mm long. The prostomium consists of 9 rings and has 4 

 terminal antennae; eyes were not described. The everted proboscis is 

 cylindrical; it has 4 pairs of chevrons, the largest one at the base. The 

 terminal end of the proboscis has 17 fleshy papillae. Macrognaths have 

 3 larger and 2 smaller clawlike teeth (Pratt, fig. 6). Micrognaths 

 number 15 in the dorsal and 17 in the ventral arc. Anterior uniramous 

 parapodia number 55. A small notopodium appears at the 56th segment 

 and increases in size gradually; the transition region is thus not abrupt, 

 but the number of transitional segments is not stated. Notosetae are 

 hairlike. Neuropodia have a bifurcated presetal lobe and a broad foli- 

 aceous postsetal lobe, as characteristic of most species of the genus. 

 Neurosetae are composite spinigers. 



G. falklandica was thought (Pratt, 1901) to have its affinities with 

 the boreal G. norvegica Oersted, but from the latter it differs sharply in 

 having a much higher number of uniramous segments, 55 in the first and 

 33 to 37 in the second. The first has only 4 pairs of proboscidial chev- 

 rons, the second has 15 to 20 pairs. G. falklandica agrees with G. eximia 

 Ehlers (1901, in part, including only the smallest specimen) in having 

 only 4 pairs of chevrons. Ehlers described a transitional parapodial 

 change from about the sixtieth segment. A specimen 77 mm long consists 

 of 168 segments. The first 3 parapodia are more weakly developed than 

 those immediately behind. Micrognaths number about 24 and are ar- 

 ranged in a circlet. Macrognaths have 3 larger and 2 smaller teeth. 

 These characters resemble those described for G. falklandica, but are
