In the recent preliminary check list of the fishes of Japan by 

 Jordan and Snyder, (1901, Tokyo, Annotationes Zoologicae Japonensis, 

 Vol. Ill, Parts II-III, p. 126) two myxinoids are mentioned, Homea 

 burgeri Girard, and Myxine australis Jenyns. The first represents the 

 form described as Heptatrema cirrhatum by Temminck and Schlegel 

 (1847, Fauna Japonica : Poissons): the second was identified, fide 

 Dr. Günther, on the evidence of specimens taken by the Challenger 

 on the " Hyalonema ground " off Misaki. In a subsequent paper 

 Jordan and Snyder (" A Review of the Lancelets, Hag-fishes and 

 Lampreys of Japan with a Description of Two New Species." Pro. U. 

 S. Nat. Mus. Vol. XXIII, pp. 725-734, 1901.) describe the Japanese 

 Myxine as a new species, M. garmani. 



* Eealizing that the time-honored nam«'. Bdellostoma, for this genus must be superseded I 

 conclude with Mr. Garman that Homea (1822, Fleming) should be selected instead of a name- 

 prior by several years (1819, Duméru, fide Cloquet, Diet. Sei. Nat. XV. p. 134). To one who is 

 not an out-and-out purist the earlier name " Eptatretus " to say nothing of its unaspirated 

 condition is clearly a misnomer for forms which usually have not seven gill opening*.
