Shells of this species were found with C. papillosa at “Fish Hawk” 
station 7723. In Europe this species has a somewhat more southern 
range than the preceding being recorded from the Mediterranean. 
Brady (’70) records this species from the Gulf of St. Lawrence and 
Brady and Crosskey (’71) record it from the post-Tertiary of Montreal. 
Cytheridea seminuda sp. nov. 
PI. 33, fig. 62-64; pi. 34, fig. 76-77. 
Shell, seen from the side, elongate, highest toward the posterior 
end, height somewhat less than half the length, dorsal margin very 
gently curved, sloping somewhat abruptly at either end; seen from 
above, elongate, ovate, widest posteriorly, subacute in front, broadly 
rounded behind. Surface of dorsal half smooth with numerous 
small rounded papillae, ventral half sculptured, with indented polyg¬ 
onal areas obscurely linear in their arrangement, especially toward 
the ventral border. Lucid spots six in number, four grouped, the 
other two in front, the dorsal one much the larger of the two. 
Antenna of the male with a peculiar comb-like claw on the end of 
the penultimate joint; second pair of feet differing much on the two 
sides in the male, right foot 3-jointed, the last two joints slender and 
rudimentary, without a terminal claw and without the setae at the 
end of the second joint. 
Length of the shell 4.2 mm.

Habitat .— Found in the deeper parts of Vineyard Sound, “Fish 
Hawk” stations 7723, 7725. 
The peculiar pectinated claw of the antenna of the male, and the 
two different sorts of ornamentation of the shell will at once distin¬ 
guish the species.
