THE :tiarkets of san fra-vcssc'o. 

 By ^V. N. LOCKlNOTONo 



111' the review of the Pleuronectidaj of San Eraiieisco (rroc. U. S. Xat. 

 Mu8. 1870, 69-108), a species belonging" to the genus Lepidopsetta (Gill) 

 is described as identical with the Flatichthys umhrosus of Girard (Pac. 

 Kail. Kep., x, 149, 1857). At the epoch when this description was writ- 

 ten, as well as on i>revious occasions when a comparison was instituted 

 between this species and the description of Girard above referred to, 

 several discrepancies were noted, yet it was not supposed possible that 

 that author had redescribed one of Dr. Ayres's species when the de- 

 scription of the latter was accessible to him. 



Such, however, as iirst pointed out by Dr. Gill, turns out to be the 

 case, and PlaUchthys umhrosus (Grd.) must sink into a synonym of 

 Leindopsetta hiUneata (Ayres), while the forni described by me as L. 

 umhrosa needs renaming. 



The synonymy of the two species will be as follows : 



Lepidopsetta bilineata.

This species is not closely related to L. hilineata. Its ctenoid scales, 

 almost uniform over the head and body, its nearly straight lateral line, 

 its smaller eyes, with a broader, flattish interorbital space, as well as the 

 differences in the form and the number of fin rays, completely distinguish 

 L. isolepis from L. bilineata. 



Typical examples are in the United States jSTational Museum.

During the infancy of the California Academy of Sciences the reports 

 of its proceedings were published in the Daily Placer Times and Tran- 

 script, a newspaper then issued in San Francisco.

 fishes from the San Francisco markets, by Dr. W. P. Gibbous and Dr.
