CHAETODON TINKERI, A NEW SPECIES OF BUTTERFLY- 

 FISH (CHAETODONTIDAE) FROM THE HAWAIIAN 

 ISLANDS 



By Leonard P. Schultz 



Recently Spencer Tinker, of the Waikiki Aquarium, kindly sent 

 to the United States National Museum three specimens of a rare 

 butterflyfish, taken in a fish trap at a depth of 15 fathoms off Nana- 

 kuli, Oahu, T. H. Comparison of these specimens with material in 

 the national collections and considerable study of the vast literature 

 on this group of fishes reveal that they represent a new species, which 

 I take pleasure in naming for Mr. Tinker, in, appreciation of his per- 

 mission to report upon it. I wish to thank Loren P. Woods, curator 

 of fishes, Chicago Natural History Museum, for confirming my opinion 

 that this is a new species.
