COPEPODS OF THE WOODS HOLE REGION

Male. — Right corner of fifth segment dark colored, highly 

 chitinized, and curved inward, left corner as in female; genital 

 segment with a stout projection on the right side; its tip made up 

 of irregular tubercles, giv- 

 ing it a broken appearance ; 

 fifth legs uniramose, left 

 leg 4-segmented, right leg 

 3-segmented, the two dis- 

 tal segments forming a 

 pair of curved and bluntly 

 pointed scissors, used in 

 handling the spermato- 

 l^hores. Total length, 

 2.9-3.2 mm. 



Remarks. — This is the 

 only record of the species 

 outside of Norway; it can 

 be recognized most easily by the structure of the fifth legs, especially 

 in the female. Boeck's brief and imperfect description left the spe- 

 cies somewhat questionable, but Sars fully established its validity.
