By LEONARD P. SCHULTZ 

 Assistant Curator, Division of Fishes, U. S. National Miiseum 



A study of the fishes of the family Sternoptichidae collected by the 

 first Johnson-Smithsonian Deep-Sea Expedition, 1933, and others in 

 the United States National Museum, has revealed a new species of 

 silver-hatchet fish, Argyropdecus antrorsospmus, so named because 

 the single spine at the posterior end of the abdomen curves slightly 

 forward.
