ish-olivaceous, below white. Pupil black, iris yellow. Length 
16 inches, without tail, and width 2 feet. Egg Harbor. 
| (Le Sueur.) 
I have no records, except an uncertain one for Stone Harbor, 
during October of 1897, since the one taken by Le Sueur for 
Egg Harbor. The Stone Harbor example was called ‘‘cow 
fish” by the fishermen, though it may not have been this species 
at all.
