THE ich TERTIARY Beps.—In Vol. 1 of the Report of the 
United States Geological Survey of the Fortieth parallel, page 
393, the able author, Mr. King, has described an extensive series 
of beds, including many laminated shales, which are found in the 
northern part of Nevada, as constituting an extension of the 
Green river formation west of the Wasatch mountains, He states 
that they contain the same species of fossil fishes as those of the 
Green river epoch. I published the first notice of this formation, 
which I examined at Osino and at Elko, Nevada, and described 
from it two species of fishes, which were referred to genera previous- 
ly unknown, viz: Amyzon and Trichophanes. These genera have not 
been found represented in the fish fauna preserved in the Green river 
shales, which embraces eight genera and twenty-four species. But 
they occur in several species and specimens in the South park of the 
Rocky mountains of Colorado, associated with the genera RAin- 
eastes and Amia, neither of which has yet been found in the 
Green river formation. The first named is common in the Bridger, 
but in a different form, and the generic identity is not yet fully 
established. The Amia is represented in the Bridger by Papp- 
icthys, but in the former the characteristic parts have not yet 
been seen in the South park specimens, so that here also the 
determination of the genus is not final, It, however remains, that 
this fish fauna is different from that of the Green river beds, and 
the modern aspect of the genera points to an age even later than 
the Bridger. It is evident that the pertinence of this series of 
rocks to the Green river formation, asserted by King, cannot be 
maintained. I have named this epoch that of the Amyzon beds, 
from the characteristic genus which it includes, and refer it to the 
later Eocene or early Miocene eras. Its fish fauna includes ten 
species, distributed as follows: TZrichophanes Cope, 3 sp.; Amy- 
Zon nea 4 sp.; Rhineastes Cope, 1 sp.; Amia L., 2 sp.—E. D.

GAUDRY ON PERMIAN VERTEBRATA. — Prof. Gaudry recently 
brought before the Academy of Science descriptions of severa ral 
interesting types of Barchi and Reptilia from the Permian of 
the Department of the Saone et — Among these was Actin- 
odon Gaudry, whose vertebrae are segmented so as to closely 
resemble those of Mickis (this journal, 1878). Another form 
allied to Protriton, was probably a terrestrial animal, and possessed
