FISHES OF NEW YORK 665 



similarly marked; head finely dotted with black; a dusky spot 

 at base of caudal in both sexes. New York to Florida. 



Mitchill found a specimen of this little blenny in an oyster, 

 and described it under the name Blennius pholis. 

 Another specimen was sent to Cuvier from New York, and a 

 specimen in the Lyceum in New York, described by De Kay, was 

 obtained from New York harbor. This blenny is common south- 

 ward in shallow water. It seldom exceeds the length of 3^ 



inches.
