THE FISHES OF NEW JERSEY. 409 
Lateral line high and concurrent with dorsal profile. Dorsal be- 
gins about over middle of pectoral and confluent around short 
rounded caudal with anal which begins about first 34 of length of 
head and trunk. Pectoral broad, a little less than 24 to anal. 
Ventral long, inserted just before posterior margin of orbit, 
reaching half way to anal, and inner ray half length of outer. 
Color in life plain pale brownish generally. Dorsal, anal and 
caudal margined with blackish-brown. Length 534 inches. Cape 
May. 
My examples from the above locality, Atlantic City and Bees- 
ley’s Point, also one from Avalon which was picked up on the 
beach October 17th, 1897, by Mr. David McCadden. It is prob- 
ably more abundant than generally supposed and on account of 
its seclusive habits, such as burying in the sand, may readily 
escape observation.
