Third epimeron : posterior edge sweepingly convex, lower corner not 

 produced, setal row increasingly admarginal along lower half of posterior 

 edge. 



Male. — Sexual dimorphism typical. Sizes 6-7 mm. 



Remarks on young animals 



The female stage described above was at first thought to be inter- 

 sexual due to the moderately large eyes and long inner ramus of the third 

 uropod but apparently the elder females develop these conditions nor- 

 mally. In young females and juveniles the eyes are small though black 

 and distinct in alcohol. Specimens at a size of 3.5 mm which bear brood 

 plates are shown in Plate 7. They have a much shorter inner ramus of 

 the third uropod, the posterior edge of peraeopod 5, article 2, is more 

 convex and the fifth articles of gnathopods 1-2 are slightly shorter than 

 the sixth articles. The last two articles (6-7) of the last 3 peraeopods
