28 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 15 



lobe is deeply bifurcated, also a small pointed postsetal lobe is first 

 present. The third parapodium is similar to the second one, but the 

 postsetal lobe surpasses the presetal ones in length. The dorsal cirrus 

 also comes to be long, foliaceous and triangular. 



A small but distinct notopodium is present on segment 32; this is 

 followed by a long transition region in which notopodia gradually in- 

 crease in size, to about segment 80-85. Notosetae are hairlike and num- 

 erous in a fascicle. Neurosetae are composite spinigers. The specimen is 

 maculate as described above for Goniada quinquelabiata. This is be- 

 lieved to be identical with the latter, and is here newly referred to it. 



Distribution. — G. quinquelabiata is known off New York in 466 

 fms, dredged by the Blake Expedition, and off Georges Bank, Mass- 

 achusetts in 30 meters, dredged by the Albatross. 



Goniada congoensis Grube 



Grube, 1878a, pp. 532-533; Arwidsson, 1899, pp. 41-43, fig. 62; Monro, 

 1930, p. 118. 



This species, together with its subspecies, below, is characterized 

 for having a midventral, longitudinal series of one or more rows of 

 proboscidial organs that differ from the others. These have a rigid, 

 clawlike base and a bifurcated distal end (see Arwidsson, 1899, fig. 62). 

 A subdistal circle, possibly a pore is shown but no mention or explana- 

 tion made in the text. An individual with 206-210 segments is about 

 61 mm long and 3.5 mm wide with parapodia. The first 27 segments 

 are uniramous; others are biramous. Notosetae are simple and hairlike. 

 Notopodia have a postsetal lobe that is as long as the presetal one. 



Proboscidial organs are of 2 kinds; most that cover the surface 

 are conical and pointed. Along the midventral length there are 4 longi- 

 tudinal rows that have furcated tip. Chevrons number 13-14 on a side. 

 Macrognaths have 4 large teeth ; micrognaths consist of a dorsal arc of 

 25-29 pieces and a ventral arc of 15 pieces. All the micrognaths are H- 

 shaped except the most lateral ones in the dorsal arc which are Y- 

 shaped. 



Distribution. — This is known only from the Congo coast and An- 

 gola, Portuguese West Africa. 



Goniada congoensis hupferi Arwidsson 



G. hupferi Arwidsson, 1899, pp. 40-41; Augener, 1918, pp. 396-397. 



This differs from the stem species mainly in the comparative lengths 



of parapodial lobes. In neuropodia the postsetal bifurcated lobe is shorter
