TWO NEW GENERA AND SOME NEW SPECIES OF 
FOSSILS FROM THE UPPER PALAEOZOIC 
. ROCKS OF MISSOURI.

PLATE XXVIII. 
It is our purpose here first to discuss two little groups of 
blastoids of which scarcely anything is known to the general 
student of this class of organisms, since they are not only verv 
limited in their distribution, but even locally reckoned among 
the rarities. 
Of group one, the first mention is probably to be found in 
Dr. Shumard's description of Pciitrcinitcs rocnicri in the old 
"Missouri Geological Survey, I and II Reports, 1855." Imper- 
fect as the description is and poor as the figures are, the author 
had before him a specimen of what has since been described 
as Granatocriniis sainpsoni. It was hardly a medium sized in- 
dividual and without surface markings, but with the rather 
large interradial (deltoid) and distinctly convex base. (I re- 
fer to his figure 2a. Figs. 2b, 2c and 2d represent another and 
c|uite distinct thing.) 
Along with his figure of Granatocriniis sanipsoni, Dr. Ham- 
bach figures one of Dr. Shumard's specimens, but it is certainly 
specimen no. 2 (2b, 2c, 2d as above) and can hardly stand for 
G. rocnicri. 
The type of the latter species came from the Chouteau lime- 
stone of Providence, Boone Co. Later collectors have found 
this form near Sedalia, Pettis Co., and in the Kinderhook beds 
at Osceola and Cedar Gap. The author of this paper has 
found it at both o^ the latter places and has obtained specimens 
of it from the other places mentioned. 
The next species of the group brought to the notice of nat 
uralists is the Codonitcs inopinatus, passing over the problem- 
atical Pcntrcmites ncglcctns, too poorly defined and ill figured 
to be able to be identified even generically. 
'\ Codoniics inopinatus was figured and described in the 
Kansas City Scientist, July, 1891. 
In the August number of the same journal and same yea"- 
thc third species was defined and figured as Granatocriniis apla- 
fiis. Two more species will follow the generic description here.
