appearing almost pointed. The spines arming the lateral margins are 

 more numerous and distally much more crowded than in N. rayii. 

 The two species also differ in the slightly different proportions of 

 the joints of the exopod of the fourth pleopod of the male. N. 

 kadiakensis also shows some similarity to N. mirdbilis and to N. 

 japonica but may be distinguished by the characters of the telson and 

 the fourth pleopod of the male. 



The pleopods of the males in the present material agree with Ort- 

 mann's description, and it is now clear that the pleopods I figured from 

 San Francisco specimens (1932b) were taken from a not quite fully 

 grown specimen, as I suggested at the time.
