Uyimrhatnphiis japonicus (Brevoort) . 



Hemirhamphus jajyonicus Brevoort, Perry's Exped. Jap., 

 1856, p. 280 ; Loo Choo, known from a figure only. 



Hyporha7?iphus japonicus Jordan and Starks, Proc. U. S. 

 Nat. Mus., Vol. XXVI, 1903, p. 535 (after Brevoort). 



The species was described by Brevoort, from a drawing ; 

 and as the species has not been seen since, Jordan and Starks^^ 

 in their " Review of the Synentognathous Fishes of Japan " say 

 that the species is very doubtful and may not differ from 

 Hyporhmn2')hus sajori. Now I have had the good fortune of being 

 able to examine a specimen of the species, which was taken on 

 Hahajima, one of the Bonin Islands, and is contained in Mr. 

 Owston's collection. I believe the species should be held distinct 

 from Hyporhamphus sajori. I give below a description of the 

 specimen.
