mostly longer than body width medially with 11-20 articles. Ventral 

 cirri digitiform, usually not extending beyond parapodia. Composite 

 falcigers having bidentate blades with short serrations (Figure 30- 

 128b, c). Inferior falcigers of medial to posterior regions with en- 

 larged teeth perpendicular to long axis of blade (Figure 30-128d,e). 

 Blade-length ratios 1.4-2:1 anteriorly, 1.8-2.2:1 medially, about 1:1 

 posteriorly. Superior simple seta minutely bidentate (Figure 30-128f), 

 present posteriorly. Inferior simple seta with two large teeth similar 

 to those of inferior falcigers, present posteriorly. Acicula with 

 twisted, acuminate tips (Figure 30-128g). Pharynx extending to setigers 

 5-8; margin smooth; middorsal tooth subterminal. Proventricle extending 

 from setigers 6-9 to 10-13, with 29-32 muscle cell rows. Ventricle 

 occupying 1-2 setigers. Pharynx 0.9-1.3 times length of proventricle; 

 proventricle 2.4-3.2 times longer than wide. Gametes present from about 

 setiger 25.

 DESCRIPTION: 



Length, to 15.3 mm (previously reported to 4.07 mm); width, to 0.7 mm 

 (previously reported to 0.29 mm). Body long, slender; complete speci- 

 mens with up to 104 setigers. Prostomium rounded to triangular, with 

 four small lentigerous eyes, and two ocular spots near base of palps 

 (Figure 30-130a). Median antenna arising between eyes, with 8-28 arti- 

 cles; lateral antennae with 7-19 articles. Palps triangular, blunt. 

 Dorsal tentacular cirri with 9-19 articles, ventral ones with 7-17 

 articles. Dorsal cirri with 7-44 articles anteriorly, 6-24 articles 

 medially. Ventral cirri digitiform, often extending beyond parapodia 

 anteriorly. Pygidium with paired cirri having 12-20 articles, plus 

 short, slender, midventral cirrus. Composite falcigers slender, biden- 

 tate, with fine serrations (Figure 30-130b-d). Superior falcigers long- 

 bladed, with knobbed terminal tooth (Figure 30-130b); blade-length ra- 

 tios 1.9-3.1:1 anteriorly, 2.2-4.7:1 medially, 1.2-3.3:1 posteriorly. 

 Superior and inferior simple setae slender, bifid or bidentate (Figure 

 30-130e,f), present posteriorly. Acicula slender, distally recurved. 

 Pharynx extending to setigers 5-11; margin surrounded by ten soft papil- 

 lae; middorsal tooth subterminal. Proventricle extending from setigers 

 6-12 to 9-16, with 32 (26-38) muscle cell rows. Ventricle occupying 1-2 

 setigers. Pharynx 0.8-1.7 times length of proventricle; proventricle 

 2.6-4.5 tines longer than wide.
