 DESCRIPTION: 



Length, 3.4+ mm (previously reported to 15 mm); width, to 0.4 mm (pre- 

 viously reported to 0.5 mm). Body small, fragile; all specimens incom- 

 plete with up to 19 setigers. Prostomium rounded, with four lentigerous 

 eyes, with or without two small ocular spots at base of palps (Figure 

 30-74a). Antennae and tentacular cirri long, slender, irregularly wrin- 

 kled, sometimes with fine hair-like projections. Palps broad, slightly 

 longer than prostomium, fused basally. Nuchal organs as large ridges 

 along posterior border of prostomium, often with brown pigment. Dorsal 

 cirri long, slender, smooth. Antennae, tentacular and dorsal cirri 

 arising from short cirrophores. First pair of ventral cirri lamelliform 

 (Figure 30-74b), following pairs auricular to digitiform, shorter than 

 parapodia. Composite falcigers with minutely serrate, bidentate blades 

 (Figure 30-74c); blade-length ratio about 1.5-2.4:1. Superior simple 

 seta slender, hair-like, minutely bidentate (Figure 30-74d), present 

 posteriorly. Inferior simple seta slender, bidentate (Figure 30-74e),
