MUNNA. 325 



The eggs in this genus are carried in a large ovisac, 

 situated between the middle legs, and composed of four 

 large plates. 



As it is very probable that Kroyer's two species will 

 be discovered in our northern seas, we add his characters 

 of both. 



Munna Fahricii, Kr., abdomen ovale vel subellipticum, 

 aperte longius quam latum ; appendicibus caudalibus rudi- 

 mentariis sed sat distinctis. Annulus thoracicus Sep- 

 timus sat distinctus. 



Munna Boeckii, Kr., abdomen capite aperte longius 

 subconicum non multo latins quam longum, appendi- 

 cibus caudalibus fere evanescentibus ; annulus thoracicus 

 Septimus parum distinctus, sexto multo brevior.
