32 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL.15 



Proboscidial organs vary somewhat. Those from the Gulf of Cali- 

 fornia are slightly more striated in their flaring edge (figs. 4-7) than are 

 those of the others (figs. 2, 3). In both, the flange is noticeably less 

 broad than that in G. brunnea (pi. 1, fig. 6). The stalk is sometimes 

 extended so as to appear like a funnel. Various views of similar organs 

 are shown in the small sketches in fig. 7. 



G. emerita (Hartman, 1944b, p. 19) from Colombia and Venezuela, 

 is here referred to G. acicula since there are 3, not 2, body regions and 

 the prostomium has 10, not 8 rings. 



Distribution. — G. acicula is recorded from both sides of tropical 

 Amei'ica, in the Gulf of California and Ecuador, and from Colombia 

 and Venezuela, in shallow water to 40 fms. 



Goniada emerita Audouin and Edwards 



Fauvel, 1923, pp. 391-392, figs. 154 h-q. 



Goniada longicirrata Monro, 1937, pp. 285-286, figs. 12 a-c. Not 

 Arwidsson, 1899. 



Length of a complete specimen of Goniada longicirrata Monro 

 (1937) with 145 segments is 40 mm and width with parapodia is 1 mm. 

 The anterior uniramous region consists of about 57 segments and the 

 transition to the biramous condition is abrupt. Notopodia have few 

 (about 2) heavy acicular setae, and neuropodia have only composite 

 spinigers. The proboscis has between 12 and 15 pairs of chevrons. The 

 distal macrognaths have 3 teeth. Micrognaths are arranged in a complete 

 circlet; they number about 22 in 2 irregular rows of larger and smaller 

 plates. The proboscidial organs are shown (Monro, fig. 12c) roughly 

 equitriangular, with a passage running up from the exterior to the 

 cential canal. Neuropodia have a bifurcated presetal lobe that is longer 

 than the single, tapering postsetal lobe. The dorsal cirrus is not elong- 

 ated. 



This specimen was questionably referred to G. longicirrata Ar- 

 widsson (1899) since the biramous region begins a little more forward 

 than in G. emerita, and the number of teeth (3) in the macrognaths 

 is low for the latter. However, to me these differences seem less signif- 

 icant than others, such as the greatly elongated cirri of Arwidsson's 

 species. 



Distribution. — Western and southern Europe; south Arabian coast 

 in 16-22 meters and Red Sea in 256 meters (Monro, 1937).
