880 CONTRIBUTIONS TO NORTH AMERICAN ICHTHYOLOGY IV. 



Ainer. 1869, 491), described from a specimen sent from San Francisco, 

 should probably not be included in this work. The species is abundant 

 on the west coast of Mexico, from which region the typical specimen was 

 most likely obtained.

Page 92. The group here called Litholepls is to be considered as a 

 section of Lepidosteus rather than as a distinct geiuis. The name 

 Atractosteus (Raf. Ichth. Oh. 1820, 73) should probably be adopted in- 

 stead of Litholepis. The name Litholepis adamantinus was given to a 

 drawing by Mr. Audubon. A copy of this drawing was preserved by 

 Eafinesqne in his field-note book, which we have examined. It is evi- 

 dently a fancy sketch, like the ^^ Pogostoma,^^ ^^Aplocentrus,^^ ^'Eurysto- 

 inus,''^ and other ichthyological myths, which the humorous artist im- 

 ix)sed on the credulous naturalist. Usox viridis L. was undoubtedly 

 intended for Lepidosteus osseus.
