quesas. When swimming they appear to ghde over the sand, from 

 which they are distinguished with difficulty when quiet. They 

 usually swim rapidly away upon the approach of a small boat, though 

 we captured a single example with the harpoon. They were found in 

 pairs, and seldom attained more than a couple of feet in width 

 of disk. 



PS ALLISOSTOMID^ . 



{Psallisostomus Klein, in Walbaum, Pet. Arted. Gen. Pise, III, 1792, p. 

 581. Type Esox osse,us Linnaeus.) 



12. Psallisostomus osseus (Linnaeus). Common Gar. 



Reported from about the Keys south of Cape Sable, but not seen by 

 me. 



ELOPID^. 



13. Tarpon atlanticus (Valenciennes). Tarpon. 



This fish is reported to be used for food by the negroes at times. It 

 is the custom of anglers to throw their bodies on the beach or shore, 

 as it is said they attract the sharks if allowed to stay in the water, 

 thus interfering with the fishing. The young were said to be not 

 quite so common, though it is possible that they may have been over- 

 looked. 



14. Elops saurus Linnaeus. Ten Pounder. 



Said to be aljundant at times. 



ALBULIDiE. 



15. Albula vulpes (Linnaeus'. Bone Fish. 



Mostly abundant. 



DUSSUMIERIID^.
