Hurley. This near absence of serrulations is also probably due to the 

 small size of the Japanese specimens. As in Hurley's description, the 

 inner margin of uropod 3 inner ramus is more finely serrate in the fe- 

 male than in the male. In the female P5 and P7 are subequal, slightly 

 longer than P6. In the male, P5 is relatively longer; the distal end of 

 P6 propodus reaches about three-fourths to the distal end of P5 

 propodus. 



The Korean specimens agree in general with the Japanese ones, 

 which appear to represent Stephensen's (1924) "short-legged" form, 

 but one lot collected west of Mok Po (34°30' N., 125°0' E.), consisting 

 of an adult female and a juvenile, agrees with Stephensen's "long- 

 legged" form, except in the shape of the carpus of P3-4. In the adult 

 female, P6 extends one-fourth the distance down the propodus of P5
