produced their mineralization. In the Museum of 
the Garden of Plants at Paris, there is a large speci-

to have been destroyed and covered with mineral 
matter, when one of them was in the very act of 
swallowing the other. Mr. Bakewell, however, who 
accurately examined this specimen, is of opinion, 
that the two heads of the fish had been oe to-

Genus Parapoxipves. S#rongniart.. 
The animals arranged ‘under this generic name, in-

tomolithus paradoxus, and Brongniart has given the 
specific appellation which the great Swedish natural- 
ist applied to these singular animals, out of compliment 
to him, though he considers it quite inappropriate. 
The late Professor Dalman calls this genus Olenus, 
and quotes Paradoxides as a synonyme, but the term

The animals belonging to the Paradoxides have the
