THE FISHES OF NEW JERSEY. 403 
Genus BLENNIUsS Linneus. 
The Blennies. 
Blennius fucorum Valenciennes. 
Blenny. 
Distinguished from the next principally by the gill-membranes, 
which are free from the isthmus posteriorly. 
This included on Dr. Abbott’s reference. It is, however, if a 
member of our fauna at all, to be found in the open sea in float- 
ing seaweed as a straggler. I have never seen any examples.
