possible that Dana's young Corophiaiti {^ quadriceps, 2 mm. long, 

 from Rio Janeiro, may be a synonym, and pi-obable that C. con- 

 tractiim. Stimpson, 185.5, from Japan, later identitied by G. M. 

 Thomson in New Zealand waters, may likewise be another name 

 for Smv's widely distributed species.

In this species Dana's figure shows the fifth joint of the second 

 gnathopod in the male as quite distinct from the long joint which 

 follows. In the example from the Falklands, as in one from the 

 ^\"est Indies, this fifth joint is scarcely visible, in this respect 

 agreeing with Podocerus maugca'evce Chevreux, 1907, of which the 

 author says that the wrist is not clearly distinct from the hand. 



It is possible that the species is not a true member of the fauna 

 of the Falkland Islands, since Mr. Vallentin records liis specimens 

 as obtained from mud on a hulk sunk in Stanley Harbour.
