4. Newport canyon, Sta. 7729, in 211 meters, mud. The photo- 

 graph (Fig. 23) shows a uniformly fine-grained mud bottom, marked 

 with grooves and ridges of embedded animals. The Analyses show 

 the recovery of a very large holothurian, Jilolpadia intermedia (Fig. 24), 

 and many tubes of polychaetes, especially Pista disjuncta and Nothria 

 pallida (same Fig.). In all 46 species and 454 specimens were taken.
