PALZASTER? DyeERI Meek. 
Among the specimens loaned to me for study and description 
y Mr. Dyer, there is a very imperfect example of one of the 
largest known Silurian star-fishes. When entire, it must have 
been from five to five and a half inches in diameter across from 
end to end of the rays of opposite sides; while its disc, as seen 
in a flattened condition, measures about two inches in diameter. 
As near as can be determined from the published description of 
Paleaster granulosa of Hall (which has not yet been figured), 
this very large specimen would seem to be related to that 
species, and may possibly be the same. Still, from its much 
larger size (P. granulosa being described as “ of medium size ne 
as well as from the want of exact conformity of some of its 
details of structure, I am led to believe it distinct. The speci- 
men, however, is unfortunately much obscured by the adher- 
ieee and descriptions of these fossils are to appear in the Ohio Geological
