Remarks. Mr. sp. Bate in his paper ..On the Penæidea* - in 

 Ann. Nat. Hist. Sept. 1S81 has shortly uientioned this genns and 

 regards it, in accordance with the statement of Dana. together with 

 Chalaraspis of Willem. Suhm as constituting a family belonging 

 to the Penæid gre up of Macrura. To this vie w I cannot consent. 

 A careful anatomical investigation af one of the "Challenger" speci- 

 mens in connexion with the description of Chalaraspis ungviculata 

 given by the late Dr. Willem. Suhm, has convinced me, that the 

 family Eucopiidæ ought much more properly to be placed among 

 the Schizopoda than among the Penæidea. As has already been 

 shown by Willem. Suhm. the adult females of Chalaraspis. which 

 genus, in my opinion, is identical with Eucopia of Dana, carry their 

 eggs and young in a marsupial poche. of the very same structure 

 as in the Lophogastridæ, and this is a feature never to be ibund 

 in any of the true Penæidea. nor in any other Macrura, while ir is 

 also characteristic for another family of the Schizopoda. the Mysidæ.
