According to Dr Smith this is the commonest shark of the 

 A\ (i(i(ls Hole region; it is found in Vineyard sound from June to 

 November. The largest are 12 feet long. Fish, crabs and other 

 animals are found in its stomach. 



Some of the teeth of a large individual were secured from 

 A. P. Latto at Southampton in July. Instead of a single basal 

 cusp, as usual, certain teeth had two such cusps on each side. 

 The last sand shark seen by me during the summer of 1898, in 

 Great South bay, was observed September 16 near the inlet at 

 Fire island, swimming slowly westward near the surface. A 

 list of specimens follows.
