distances from the surface. On this trip about 105 speciesof 
Invertebrates were obtained, not including the Foraminifera and 
other minute forms. There were amon g these 14 species of 
Anthozoa; 2 of Hydroids; 22 of Echinoderms; 38 of Mollusca;

dredged by the Albatross, many of which are new to our 
coast, though ey dredged on the European side, or in. a 
the Caribbean Sea and still more distant regions. Others a a 
undescribed forms. Among the Holothurians were two poy A

many species were brought to light by the Challenger expedi-
