COPEPODS OF THE WOODS HOLE EEGION 



63 



I 



Occurrence. — Reported by Sharpe from a surface collection off 

 Nausett Beach, Cape Cod ; also from Station 627, Grannpus^ off north- 

 ern shore of Cape Cod. 



Distributiori. — Mediterranean (Giesbrecht) ; North Atlantic 

 (Cleve) ; South Atlantic (Cleve, Stebbing) ; Indian Ocean (Thomp- 

 son and Scott) ; Adriatic (Pesta) ; Califor- 

 nia coast (Esterly) ; off Cape Cod (Sharpe). 



Color. — Body transparent with red spots 

 in the head and thorax, and sometimes on 

 the caudal rami; plumose setae of maxil- 

 lipeds and caudal rami often with a wash 

 of red, more or less intense ; eye minute and 

 ruby red. 



Femiale. — Genital segment symmetrical, 

 scarcely protruding ventrally, with a flap- 

 like process on either side of the genital 

 opening; second inner seta on each caudal 

 ramus elongated; first antennae reaching 

 about one segment beyond the caudal rami ; 

 end segment of second exopod invaginated 

 at the base of the second spine on the outer 

 margin; basipods and rami of fourth legs 

 more or less covered with short spines. 

 Total length, 6-6.2 mm. 



Male. — Unknown. 



Remarks. — This species can be distin- 

 guished most easily by the invaginated end 

 segment of the second exopod. It must 

 be quite rare, since it did not appear in the 

 extensive collections made by the Fish Hawk and the Albatross.
