Pseudocalanus elongatus, Boeck. 
This ubiquitous species seems plentiful at all seasons. 
Mecynocera clausit, Thompson. 
Frequently met with. 
Pleuromma abdominale, Claus. 
Occurs very sparingly. 
Heterocheta spinifrons, Claus. 
Fairly abundant. 
Leucartia flavicornis, Claus. 
Found in considerable abundance. 
Scolecithrix dana, Lubbock. 
Occurs sparingly. 
Eucheta prestandreew, Phillipi. 
This is by far the most numerous of the species obtained, 
and forms the chief proportion of all the gatherings. Males 
and females occur in about equal quantities, the latter 
being usually provided with oyvisacs. 
E. barbata, Brady. 
This species was found very sparingly, though from the 
close resemblance between EH. prestandrew and E. barbata 
it is probable that some of the latter may have been 
overlooked. 
Candace pectinata, Brady. 
C. pachydactyla, Dana. 
C. truncata, Dana. 
C. bispinosa, Claus. 
C. mgrocincta, ‘Thompson. 
The three first named species of Candace were very 
common; the two latter were rare.
