A NEW GENUS AND FIVE NEW SPECIES OF 

 AMERICAN FISHES 



By SAMUEL F. HILDEBRAND 

 U. S. Fish and Wildlife Serxnce 



The 'new forms lierein described were discovered more or less 

 incidentally during the past several years while working with various 

 groups of tropical and subtropical fishes. It seems advisable to pub- 

 lish the descriptions now, as some of the names are desired for 

 inclusion in a general work. 



The types of the new species are all in the National Museum, and 

 their catalog numbers are given in the accounts of the species. The 

 writer is indebted to Dr. Alexander Wetmore, Secretary of the 

 Smithsonian Institution, and to Dr. Waldo L. Schmitt, head curator 

 of zoolog}', and Dr. Leonard P. Schultz, curator of fishes, in the 

 National Museum, for laboratory space and for the use of the speci- 

 mens needed in the studies that led to the discover}- of the new genus 

 and the new species described in these pages.
