Coles — Notes on the Sharks and Rays of Cape Lookout, N. C. 93 

 21. Narcine brasiliensis (Olfers). 



SMALL ELECTRIC RAY; SHOCK FISH. 



In 1909 it was my good fortune to add this interesting electric ray to 

 this region, as well as to the east coast of the United States. During each 

 succeeding year I have noted that this fish arrives in the biglit of Cape 

 Lookout on the night of June 29, and departs on the night of July 4. It 

 is seen in this region at no other time during the year. 



22. Urolophus jamaicensis (Cuvier). 



In June, 1911, I captured a small example of this West Indian ray at 

 Cape Lookout. This species had not previously been reported as occurring 

 on this coast. 



23. Dasyatis hastata (Dekay). 



STING RAY. 



In July, 1910, at Cape Lookout, I captured a 64-pound female, which 

 gave birth to five young rays while she was being killed. This species 

 had not previously been reported .as occurring on this coast. 



24. Dasyatis say (Le Sueur). 



STING RAY. 



The commonest of all the sting rays in this region. It can be found 

 there from the first of May till November. 



25. Pteroplatea maclura (Le Sueur). 



SAND SKATE; BUTTERFLY RAY. 



This ray is very common in this region. Most of the specimens seen 

 are less than a foot in width. I have occasionally seen individuals more 

 than 2^ feet in width. 



26. Pteroplatea altavela (Linnaeus). 



A new addition to the fauna of North Carolina, and the first definite 

 record for North America, was made on May 22, 1914, by the capture of 

 a large female of this species near Cape Lookout. The widtli of the disc 

 of this specimen was six feet ten inches. It was captured by Mr, Charles 

 AV. AVillis, the captain of my boat and member of crew. From this speci- 

 men four well-developed embryos were taken ; the largest had a width of 

 M}4 inches and the smallest 15 inches. All had well-developed spines on 

 tlie tails. 



I was informed later by a native fisherman that at about the same date 

 he caught in his seine in the bight of Cape Lookout, two large rays, which 

 he described as follows: " Tiiey were the biggest sand skates that I ever 

 aaw and they had stings on their tails." I am convinced that the North 

 Carolina coast was at that time visited by a school of these rays.
