the first 12 of these Albatross stations and from 3 Monaco stations; 
present in all the plankton lists except the Wilkes, but nowhere 
reported as abundant.

Stations 16; 27; 2195; 2219; 4705; 5287; 5437. Identified by Sars 
from 3 of these Albatross stations and from the 28 Monaco stations; 
found at five stations in the Carnegie plankton and listed in the Chal- 
lenger plankton under the name of Huchaeta hesset.

4736. Identified by Sars from 20 of these Albatross stations and 
from 35 Monaco stations, the latter in his preliminary report (1905a, 
p. 4). In his final report (1925, p. 68), however, he transferred the 
Monaco specimens to With’s species intermedia. In his examination 
of the Albatross plankton Sars drew the figures here reproduced and 
labeled them venusta, recognizing that they were different from énter- 
media. ‘They do not correspond with the figures of intermedia pre- 
sented in his Monaco report but do agree fully with Giesbrecht’s 
figures of venusta in the Naples report. This is especially true of 
the basipod of the fourth leg, as can be seen by comparing figure 97’ 
here shown with plate 15, figure 19, of the Naples report. These AJ- 
batross specimens show the same stout bipartite spine and scattered 
spinules. Incidentally, these figures of Sars are the first full-length 
“portraits” of this copepod. The genital segment of the female has 
a projection with a semicircular sinus at the left posterior corner as 
an aid to identification.
