K, telson. 

 Male, young, 7 mm, Sta. 1372-41. Figs. L, antenna 2; M, telson; N, uropod 3. 

 Male, 9 mm, Sta. 279-34. Fig. O, uropod 3. 

 Female, 9 mm, Sta. 456-35. Fig. P, pleon segment 3. 

 Juvenile, 3.25 mm, Sta. 2611-54. Fig. Q, uropod 3. 



The inner ramus of the third uropod in juveniles is half or less as
