CLASS PISCES. 



The work by Agassiz, " Recherches sur les Poissons fossiles" — (Text,) Tome 1-5 ; 

 (Atlas,) Tome 1-5 — was published in parts from 1833 to 1844, and very irregularly. 

 The copy in the Public Library at Cincinnati does not show when published. Wood- 

 ward & Sherborn, in " A Catalogue of British Fossil Vertebrata, 1890," have pub- 

 lished the dates at which each plate and part of the text was published. The list 

 covers about five pages. From this list of dates I make the following corrections : 

 Acanthodes, 1833; Acrolepis, 1834; Ceratodus, 1838; Chirolepis, 1835; Chomato-
