possible that Dana’s young Corophium (?) quadriceps, 2 mm. long, 
from Rio Janeiro, may be a synonym, and probable that C. con- 
tractum Stimpson, 1855, from Japan, later identified by G. M. 
Thomson in New Zealand waters, may likewise be another name 
for Say’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 
West Indies, this fifth joint is scarcely visible, in this respect 
agreeing with Podocerus mangareve 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 his specimens 
as obtained from mud on a hulk sunk in Stanley Harbour.
