until October. The usual length of individuals taken there is 5 feet. The shark is 

 present every year in variable numbers, and is caught in traps in Vineyard Sound 

 and Buzzards Bay. 



5. Great Blue Shark [Prioiiacc glaiica LinnjEus). 



This is a large shark of the warm seas and is occasionally taken on our coasts^ 

 A few individuals are recorded from San Francisco and Monterey, California. At 

 Woods Hole, Mass., the species is very rare ; a single example was obtained from 

 a trap in July, 1877. 



6. Dusky Shark [Carcliarhiniis obsciirus Le Sueur). 



The Dusky Shark lives in the Middle Atlantic and is frequently taken on our 

 Eastern coast. It reaches the length of 9 or 10 feet. DeKay did not see the fish, 

 but quotes the description and copies the figure from Le Sueur who had the species 

 from New York. 



A young individual was caught in a pound at Islip in August, 1898. Another 

 small one, 22^ inches long, and without trace of an umbilical scar, was captured in 

 a gillnet set off Widow's Creek, September 27, 1901. It had been feeding upon 

 soft edible crabs. 



7. Milbert's Shark {Carcharhinus viilberti ^I. & H.). 



Milbert's Shark is the small Blue Shark of Mitchill and DeKay. DeKay had a 

 specimen about 2 feet long and gives the greatest size known to him as 6 feet. He 

 says the shark is frequently taken in New York and extends along the coast to 

 New Hampshire. DeKay also describes this shark by another name, that of the 

 Long-tailed Porbeagle, which was obtained at Brenton's Reef, on the coast of 

 Rhode Island. The example was 7 feet 4 inches long. When captured the 

 stomach was filled with large fish which were too much injured to be identified. 

 This species ranges from Cape Cod to Florida. 



Prof. Baird mentioned this shark in the first Report of the L^. S. Fish Commis- 

 sion. Four individuals, each about 4 feet long, were taken in a trap at Woods Hole, 

 August 8. 1873, and sent to Washington. None have since been observed there. 

 The color, according to Mr. Edwards, was an intense, almost indigo, blue. 



8. Round-nosed Shark (Aprionodon isodon M. & H."). 



The Aprionod'on is found in the Atlantic Ocean and has been recorded from New 

 York, Virginia and Cuba. It is believed to be a rare fish. Muller and Henle 

 attribute this shark to New York. In Glinther's Catalogue it is called Carcharias 

 piinctatiis.
