oi the second pair of feet, projects slightly beyond the base of the first outer-edge spine on 

 the third joint. The second outer-edge spine on the third joint, extends to the base of the 

 third outer-edge spine. The appendicular seta on the furcal joints is longer than the others. 

 Length 3,75 mm. 



This species appears to have a very limited distribution.

The last thoracic segment of the female appears asymmetrical when vievved from above. 

 The right side is distinctly more produced than the left. The genital segment is also asym- 

 metrical. The right side is irregular in outline and is dilated near the distal end. The projecting 

 part of the second joint of the left exopodite of the male fifth pair is coarsely toothed, and is 

 easily distinguished from Euchaeta concinna. 



The female form described and figured by Wolfenden as Euchaeta indica, is identical 

 with the female of Euchaeta marina. 



Ettchaeta marina appears to be generally distributed in the warm seas.
