 1821.

Genus ABLENNES Jordan and Fordice 



Afhlennes Jordan and Foedice, Proc. U. S. Nat. Mus., vol. 9, p. 342, 1886. [Type, 

 Belonc Mans Cuvier and Valenciennes, changed to Ablcmies (Athlenucs is a 

 misprint) by Internat. Comm. Nomencl.] 



ABLENNES HIANS (Valenciennes) 



Beloite liians Y^vi^enciennes, in Cuvier and Valenciennes, Histoire naturelle des 

 poissons, vol. 18, p. 432, pi. 548, 1846. 



Walforcl's type of Ahlennes pacificus in the U. S. National jVIiiseum 

 is based on a very poorly preserved specimen, and the differences 

 pointed out by him jDrobablj^ will not hold good when better speci- 

 mens from the same locality are studied. My single specimen does 

 not appear to differ from Atlantic specimens. 



115197, off Enderbury Island, July 20, 1939, Lt. T. D. Shriver, U. S. N., 1 

 specimen, 1,020 mm. in standard length.
