204 Twenty-fourth Report on the State Museum. 



We propose to compliment the Rev. Sylvester Cowles, the ori- 

 ginal discoverer, who has taken much pains in bringing to light these 

 peculiar forms, and in endeavors to ascertain their true nature, by 

 naming the Salamanca species Hyppodophycus Cowlesi. 



A very fine slab of the sandstone, measuring three feet by four, 

 and bearing on its surface twenty-two of the impressions, has been 

 received at the State Museum, and placed on exhibition on the outside 

 of the Hall on State street.
