types of the latter two are minimal, and Gulf of Mexico BLM-OCS speci- 

 mens exhibit intermediate characteristics which further diminish these 

 differences. Thus, S_. tigr inoides is hereby synonymized with S. 

 cor allicolo ides .

 DESCRIPTION: 



Length, to 5.5 mm; width, to 0.2 mm. Body small, slender; complete 

 specimens with up to 43 setigers. Prostomium rounded, with four len- 

 tigerous eyes (Figure 30-140a). Median antenna arising between eyes, 

 with 9-20 articles; lateral antennae with 5-9 articles. Palps short, 

 blunt, triangular. Dorsal tentacular cirri with 6-11 articles, ventral 

 ones with 3-7 articles. Dorsal cirri short, digitiform, not alternating 

 in length, with 2-12 articles anteriorly, 4-7 articles medially. Ven- 

 tral cirri ovoid, shorter than parapodia. Pygidium with paired cirri 

 having 4-7 articles, and a broad, triangular midventral projection. 

 Composite falcigers bidentate with short, coarse serrations (Figure 30- 

 140b, c); blades often curved and basally broad; blade-length ratios 1.8- 

 2.2:1 anteriorly, 1.7-2.2:1 medially, 1.3-2.1:1 posteriorly. Superior 

 simple seta serrate, distally rounded with subdistal shelf-like projec- 

 tion (Figure 30-140d), present from midbody region. Inferior simple 

 seta bidentate (Figure 30-140e), present posteriorly. Pharynx extending 

 to setigers 4-7; margin surrounded by ten soft papillae; middorsal tooth 

 subterminal. Proventricle extending from setigers 4-8 to 7-12, with 21- 

 26 muscle cell rows. Ventricle occupying one setiger. Pharynx 1-3.4 

 times length of proventricle; proventricle 1.8-3.2 times longer than 

 wide.
