réintroduction. 



Since the publication of the report on the " Flounders and Soles 

 from Japan, collected by the United States Bureau of Fisheries steamer 

 ' Albatross ' in igoó," 1 some additional facts 2 have come to light, and 

 are added to the literature of ichthyology in the following notes. A 

 discussion of the species Hippoglossoides is also presented. 



II.— Japanese Flounders (other than Hippoglossoides). 



Pseudorhonibus inisaliitts Jordan and Starks. 



The characters separating this species from P. arsius are : the 

 presence of a white bordered ocellus on the lateral line, more rays in 

 the dorsal, and a deeper body ; these statements through a clerical 

 error were reversed by Hubbs (I.e., p. 463) in quoting Snyder. 



Genus Acanthopsetta Schmidt. 



Acanthopsetta in its technical characters is close to Hippoglossina, 

 a genus from the eastern Pacific. The two genera, however, are of 

 dissimilar habitus, and probably of independent origin.
