former covering a large part of the dorsal surface of the metasome ; 

 appendages and caudal rami the same color as the body. In the male 

 the body is iridescent, showing all the colors of the rainbow, and in 

 addition gold and silver. (Kathbun.) 



Female. — Head a little wider than long, the greatest width just 

 behind the center; corneal lenses invisible in dorsal view; metasome 

 segments squarely truncated posteriorly, with projecting corners; 

 fifth segment half the width of the fourth, considerably dilated 

 through its center; caudal rami about twice as long as wide. Third 

 and fourth segments of second antenna the same length, the two 

 together much shorter than the second segment; fourth endopod 

 longer than the exopod, its two apical setae subequal. Total length, 

 1.9-3.15 mm. 



Male. — Head a little wider than long ; corneal lenses on the ventral 

 surface some distance behind the frontal margin; urosome nearly as 

 wide as metasome. Terminal segment of second endopod with three 

 large lanceolate flanged spines, three setae and four small spines 

 around the apex. Total length, 2.15-3.15 mm. 



Remarks. — This is another tropical straggler coming into the area 

 by way of the Gulf Stream, but the eight males taken in Vineyard 

 Sound show that it occasionally drifts a long way out of the Gulf 

 Stream. Wheeler's specimens were found in company with chains of 

 Salpa cordiformis, and this tunicate may be taken as the probable 

 host of the present species.
