Anterior pair of eves are directed forward; the base of the paired 

 prostomial antennae is over half as long as the main portion of the 

 style. Palpi, antennae, and cirri are smooth (fig 38, h). Acicula 

 and setae are dark amber, but the distal ends of the acicula are darker 

 and project beyond the acicular lobes. Xotopodial setae are entire 

 distally, the transverse rows of pectinae fine, numerous, and extensive 

 in width (fig. 38, c).

Notopodial and neuropodial setae are slender, about equally thick, 

 with extensive pectinated region. Acicular lobes of both notopodia 

 and neuropodia are long, digitate throughout (fig, 37, d). The noto- 

 aciculum emerges near the tip of the lobe, the neuroaciculum about 

 halfway on the free length of the lobe. Ventral cirri are ciliate, dorsal 

 cirri smooth.

Notopodial setae are reduced in number; there are few (5 to 6) in 

 anteriormost parapodia (5 in the third foot), and they decrease gradu- 

 ally in number to the twelfth segment, where only an aciculum is 

 present. Notosetae, where present, are short, stout, finely |">ectinated, 

 with tip entire (fig. 39, e). Dorsal cirri are unusually elongate be- 

 yond the bulbous region (fig. 39, d). The acicular lobes of notopodia 

 and neuropodia are produced, but the acicula do not extend beyond 

 the fleshy lobes.

It is likely that /S. foi^nosus and S. praelongus Marenzeller (1902, 

 p. 575), from south Japan, are identical. The parapodial and setal 

 outlines are similar except that in S. for^mosus the neuroacicular lobes 

 are somewhat spatulate distally (fig. 39, c) and seemingly tapering in 

 S. praelo-ngus. Ventral cirri in both are short, inserted proximally 

 on the foot (fig. 39 c).
