 the winter, but not at all in summer. 



Mitchill had the ray from Barnegat and from oft' Sandy Hook, 

 De Kay did not see the fish, but copied the description and figure

 allusion to its habit of rolling itself up when caught. At South- 

 ampton L. 1. this species was taken in small mimbers Aug. 3, 



1898.
