5. Two species of Fossil Asterias in the Blue Limestone of Cincinnati ; 
by Messrs. G. Granam, J. G. ANTHONY, and W. P. James, (from the 
report of a Committee of the Western Academy of Natural Science, 
communicated by the Academy to this Journal.) —The largest of the 
two specimens, belonging to Mr. W. P. James, appears to be a true As- 
terias as the genus is at present constituted, having all the characters of 
that genus, so far as the examination of one side only enables us to 
judge. The specimen is in a very perfect state of preservation, having 
the rays nearly entire, and the spiny projections surrounding the mouth 
beautifully exhibited. The size of the fossil is that of the A. auran- 
tiaca, of the British coast, being about 4 inches across.*

The smaller specimen, discovered by Mr. Robert Clark, we find to 
belong also to the Echinodermata, but to a different genus, the “ Goni- 
aster of Agassiz,” commonly called the ‘cushion star,” from the 
gibbous appearance of its upper surface. This specimen is very small, 
measuring not quite of an inch from one extreme point to the oppo- 
site, Its outline is perfect, but it presents only its upper surface. 
regard the discovery of these two specimens of Echinodermata 
with peculiar interest. For a long time the Crinoidea were supposed 
to be the only representatives of Echinoderms in the blue limestone 
around our city. Subsequently the discovery of numerous remains of
