 DESCRIPTION: 



Length, 23+ mm (previously reported to 300 mm); width, to 1.2 mm (pre- 

 viously reported to 4 mm). Largest specimen incomplete with 103 seti- 

 gers. Prostomium (Figure 29-24a) with small lateral antennae. Palps 

 with small palpostyles (Figure 29-24b). Tentacular cirri about equal in 

 length to dorsal cirri of setiger 1 (Figure 29-24a,b); following dorsal 

 cirri smaller. Dorsal cirri of anterior 4-8 setigers (Figure 29-24a,c) 

 without distinct cirrophores; more posteriorly with distinct cirrostyles 

 and inflated cirrophores (Figure 29-24d). Ventral cirri beginning on 

 setiger 1. Body with numerous large papillae dorsally and on anterior 

 and posterior sides of parapodia (Figure 29-24a,c,d); with few small, 

 scattered papillae ventrally (Figure 29-24b,c). Neurosetae minutely 

 bifid, with serrate margins (Figure 29-24e). Pygidium with numerous 

 papillae and a pair of short anal cirri (Figure 29-24f). 



REMARKS: Pettibone (1966:161) considered Pilargis maculata Hartman, 

 1947b, to be a synonym of Pilargis berkeleyae. This view is not adopted
