Isurus tigris (At wood). 



An example about 8 feet long, captured at Seaside Heights, 

 August 26, of which I have a photograph, appears to be this species. 

 Another about 9 feet long, captured off Atlantic City in August and 

 brought to Somers Point, is probably identical. These are the only 

 recent records known to me. 



Mustelus mustelus (LinnI). 



Atlantic City and Somers Point. 



Eulamia milberti (Muller and Henle). 



One adult at Seaside Heights during midsummer and examples 

 in Delaware Bay at Fishing Creek; one example 8 feet long, caught 

 September 17, examined. 

 Sphyrna zygaena (Linn6). 



Common off Atlantic City, all small.

Rhinoptera bonasus Mitchill. 



On September 24 an adult, estimated at 40 pounds in weight, caught 

 in the surf at Sea Isle City on a hook baited with clam. Mr. W. J. 

 Fox has given me its caudal spine. In the same month three other 

 examples were taken at Somers Point, weighing from 2.5 to .50 

 pounds. 

 Amiatus calvus (Linn6). 



Mr. W. H. Strang reports a male taken in Cresson Lake, Camden 

 County, on July 5. This is the first record of this introduced species 

 brought to my attention.

Alosa sapidissima (Wilson). 



Bivalve and Bayside. About 70 pounds, reported taken off Sea
