A young individual, about 3 inches long, was caught in Mr 

 John B. De Nyse's pound, Gravesend bay, Oct. 22, 1897. The 

 species had not been certainly known before to occur north of 

 Charleston S. C. De Kay described and figured it as a New 

 York species solely on the authority of Cuvier and Valenciennes. 

 Dr Smith records the capture of a few specimens in the vicinity 

 of Woods Hole Mass, during the summer of 1900. It was last 

 observed on October 3 when one example was taken.
