I know nothing of the origin of this species, except that it is said to have been taken on 
the shore of Long island. It is possibly the species named triqueter by Dr. Smith, and which 
he represents as “inhabiting the vicinity of Long island, New-York, but rarely makes its 
appearance so far to the north as Massachusetts, unless driven on shore by the violence of 
storms.” 'The traqueter of Artedi, however, has no spines. It bears a considerable resem- 
blance to the O. turritus of Forshal, from the Red Sea; but that species is quadrangular.
