NO. 3 hartman: submarine canyons 85 



pair of long nephridia can be seen. The anal vesicles are very long. 

 The fecal pellets in the alimentary tract are cylindrical, capsule-shaped, 

 measure (in largest individuals) about 1.72 mm long and 0.64 mm 

 across ; when extruded these pellets are slightly annular. 



Specimens from Redondo canyon, and perhaps also other canyons, 

 harbor a commensal crab. 



The species was first named from Monterey Bay, California, in 

 222 fms, in soft gray mud. The present specimens are from 146 to 

 7 1 1 meters, southern California. 



Echiuroid, not identified 



Coll. — Newport en, in 555 m (2), 478 m (tongue of a large one). 



La Jolla en, in 637 m ( 5 ) . 



Catalina en, in 362 m ( 1 large) , 379 m ( 1 large) . 



These individuals differ from Arhynchite californicus (above) in 

 having the surface epithelium distinctly papillate throughout and the 

 epithelium is thinner, somewhat translucent. 



Listriolobus pelodes Fisher, 1946 



Coll. — Hueneme en, in 177 m (75), 183 m (3). 



Redondo en, in 107 m ( 1 large) . 



This species is most concentrated in shelflands along the Santa 

 Barbara- Ventura shelf (Barnard and Hartman, 1959, p. 6). The 

 present specimens come from the upper ends of northern canyons. In 

 life specimens are pale or grayish green and somewhat translucent.
