 long; color greenish with a dark median dorsal 

 stripe and a faint ventral one. Prostomium (Fig-

 completely covered with compressed papillae 

 irregularly arranged. First tentacular segment

1 + Oy + 



and separate. Four pairs of long cylindrical 

 tentacular cirri but no setae; tentacular formula: 



' O'j^T- Dorsal cirri (Figure 3n) large 



and oval; setigerous lobes blunt; ventral cirri 

 slender and pointed, far longer than setigerous 

 lobes. Setae (Figure 3o) with faintly striated 

 shaft-heads. 



Rcniarkn. — Ph. paiiaiHciisis is very close to 

 Pli. a)-(')utc differing mainly in the color pattern; 

 possibly it is no more than a subspecies of 

 Ph. areiKic. 



Rero)-ds. — Two specimens from 80 to 120 m 

 off Beaufort (*). 



Dii<tribiiti(>)i. — Panama: 10 m.
