 Cansidering the number and characters of the genera into 

 which the old genus M)jsis has now been divided, M>/sis mixta 

 can no longer remain in the same genus as M. ocidata. I 

 therefore propose a genus Michtheimi/sis to receive it. From 

 Ml/sis, as represented by ili. ocidata and its allies, it differs in 

 having the antennal scale unprovided with a second joint, but 

 drawn out to an excessive length, and finally terminated in a 

 spine-like point. In the male the sexual fourth pleopod is 

 quite different from the same organ in Mysis (proper) and 

 agrees in structure with that of ScJustomi/sis.
