COPErODS OF THE WOODS HOLE EEGION 



129 



Female. — First antennae reaching at least four segments beyond 

 the caudal rami, the basal segments considerably enlarged; urosome 

 two-fifths as long as metasome; genital segment protruding a little 

 on the left side and ventrally, mak- 

 ing it slightly asymmetrical ; caudal 

 rami six times as long as wide, 

 outer seta one-third the length of 

 the ramus from its tip ; fifth legs re- 

 duced in size, endopod not reaching 

 beyond the second segment of the 

 exopod. Total length, 6-6.5 mm. 



Male. — Body shorter and more 

 slender than that of the female, 

 first antennae as long, the grasping 

 antenna on the left side ; second basi- 

 pods of fifth legs protruding in- 

 wardly against each other; end seg- 

 ment of right exopod turned back 

 against the basal segment, end seg- 

 ment of right endopod armed with 

 six stout plumose setae; left endo- 

 pod reaching beyond the tip of the 

 second exopod segment ; end segment 

 of left exopod scarcely longer than 

 the second segment. Total length. 

 5.5-6 mm. 



Remarks. — The large size of this species and the length of the first 

 antennae are distinctive characters, which can then be supplemented 



by the form of the fifth legs. Evidently 

 the species is nowhere very abundant.
