FISHING FOR SHARKS IN KEY WEST HARBOR 



E. W. GUDGER 



In this paper the capture was described of a 7-foot, lo-inch male speci- 

 men of Hypoprion brevirotris and a lo-foot, lo-inch female specimen of 

 the tiger shark, Galeocerdo tigrinus, in Key West Harbor, in July, 1912. 

 These two fishes not being very well known, it is proposed later to pub- 

 lish careful descriptions with exact measurements. 



The jaws of the tiger shark, which were exhibited, measured i foot 4 

 inches straight across, and around the curve of the jaws i foot 9 inches. 

 Its stomach contained more than a half barrel of miscellaneous material, 

 including a cow's head (dehorned) minus the lower jaws, the vertebral 

 column of a sheep, the scutes of a green turtle, the bones and feathers 

 of two birds, and a lot of tin cans and sea weed. The uteri were dis- 

 sected, but unfortunately the fish was not in breeding condition.
