THETIS SCIENTIFIC RESULTS. 



in the middle, but separate at the base and apex. The latter is 



tipped by four or five setse. 



Uropods as long or a little longer than the telson ; outer ramus 



three times as long as broad; outer margin slightly convex, 



glabrous except at the tip ; inner 

 nearly straight, crenate and 

 setose throughout. Basal joint 

 of inner ramus two-fifths longer 

 than broad; margins straight, 

 the inner glabrous, the outer 

 setose; distal border oblique, 

 slightly produced at the inner 

 angle. Terminal joint twice as 

 long as broad, outer margin 

 evenly curved, inner strongly 

 convex, especially at the base, 

 both bearing numerous setae. 



Telson lanceolate, constricted 

 near the base, widening out at 

 the middle, and thence gradually 

 converging to the rather narrow, 

 rounded, sparsely setose ex- 

 tremity. 



Colour, pale creamy-white.
