SUMMARY OF RESULTS. 
371 
Ophiocnida scabrci, n.sp., is reported from this Station (Lyman, Zool. pt. 14), but 
it probably came from the dredgings on September 10 (Station 122). 
The expedition remained at Bahia from September 14 till September 25, 1873. 
During the stay at Bahia the steam pinnace was engaged several days dredging in the 
bay. In some places the deposit was a white quartz sand, containing fragments of 
felspar, mica, magnetite, hornblende, and other minerals, and also fragments of 
Echinoderms, Polyzoa, Serpulse, and other organisms. In other places it was a dark mud, 
containing, along with fine argillaceous matter, all the above-mentioned minerals and 
organisms. The dredgings were very successful, animals belonging to all the principal 
invertebrate groups being taken ; Astrophytons and Ophiurids were especially abundant.

in shallow water at Bahia during the visit : —
