lated form. In it, however, the notopodia are first present from segments 

 26 to 28. 



Distribution. — Brazil ; Panama ; eastern Pacific, from Monterey Bay, 

 California, south to Costa Rica ; Galapagos Islands. In depths to 90 fms. 

 Moore reported G. armigera from California, in depths of 36 to 271 fms.

 Key to Species 



1. Notopodia provided with blunt, acicularlike setae; notopodial 

 setae first present after the sixtieth segment; the distal, free end 

 of the proboscis has a series of 17 dorsal and 13 ventral smaller 

 chitinous pieces G. acicula, p. 252 



1. Notopodia provided with setae terminating in a slender point; 

 notopodial setae first present anterior to the sixtieth segment; 



the distal end of the proboscis with fewer small plates ... 2 



2. Notopodia first present after the fiftieth segment; chevrons 

 with 9 V-shaped pieces on a side ; the distal end of the proboscis 

 with 3 ventral and 4 greatly reduced dorsal teeth, in addition 

 to the larger lateral plates G. maculata, p. 251 



2. Notopodia first present from the thirty-eighth segment; chev- 

 rons with about 16 pieces on a side; the distal end of the pro- 

 boscis with 3 ventral and 9 dorsal pieces, in addition to the later- 

 al plates G. uncinigera, p. 252

Length to 57 mm, a posterior piece lacking. Notopodial lobes are first 

 present from the fifty-first segment, but from the fifty-sixth segment the 

 notopodia are abruptly larger and setae are present. The prostomial an- 

 tennae are distinctly biarticulated, the distal article tiny, papillar, less 

 than one fourth as long as the basal article. 



The proboscis terminates in 18 soft papillae. The larger, lateral teeth 

 ( macrognaths ) are black, with 5 claws, decreasing in size from dorsal to 

 ventral ends. The smaller plates (micrognaths) number 3 ventrally; 

 these do not nearly fill the space between the macrognaths. There are 4
