COPEPODS OF THE WOODS HOLE REGION 



107 



Distribution. — Sulu Sea (Dana) ; Hong Kong, Amoy (Gies- 

 breclit) ; tropical Atlantic (Cleve) ; New Zealand (Kramer) ; Gulf 

 of Guinea (T. Scott) ; Gulf of Maine (Bigelow). 



Color. — No statement with reference to the color has ever been 

 made. 



Female. — Urosome relatively shorter and more slender than in the 

 preceding species ; anal segment shorter than the first abdominal seg- 

 ment and somewhat asymmetri- 

 cal; caudal rami seven times as 

 long as wide, the right one a little 

 longer than the left; the second 

 inner terminal seta of each ramus 

 enlarged at the base ; the inner 

 and outer marginal spines on the 

 terminal segment of the fifth legs 

 much shorter and weaker than the 

 2 apical spines, of which the inner 

 is considerably the longer. Total 

 length, 1.4-1,6 mm. 



Male. — Anal segment and cau- 

 dal rami symmetrical, and the 

 bases of the apical setae not en- 

 larged; terminal segment of left 

 fifth exopod a little wider than 

 the basal segment and somewhat 

 enlarged and bluntly rounded dis- 

 tally, the 2 apical spines stout and 

 subequal ; endopod slender, 

 slightly curved and reaching the 

 tip of the exopod; terminal segment of right leg short, wide, and 

 curved inward, apical claw as long as the segment. Total length, 

 1.3-1.5 mm. 



Remarks. — This is a rare species and does not occur in sufficient 

 numbers to make it of any economic value. It is present in abun- 

 dance in the plankton of Chesapeake Bay and vicinity, but is only a 

 straggler from the south in the Woods Hole area. It can be most 

 easily recognized by the well-marked difference in the size and form 

 of the fifth legs in both sexes.
