Fossils of N. E. Missouri.—Rowley. 305 
specimen was found by Mr. D. K. Greger and given to the writer 
in whose collection all the specimens now are. 
Cyathocrinus Snivelyi, n. sp. 
PLATE XVIII. 
Fic 6. Side view of the dorsal cup of the type specimen. 
Fie. 7. Basal view of the dorsal cup of the same. 
Fic. 8. Top view of the dorsal cup to show the thickness of the plates. 
Body rather large, length and breadth equal. Column 
large and round. ‘The five infrabasals in the type specimen 
are of unequal size, two being much shorter than the other 
three, thus giving a greater length to one side of the fossil 
than to the other. The infrabasals if of the same size would 
be a little wider than long. 
Four of the five basals are hexagonal and of equal length 
and width. The fifth is heptagonal, supporting above a pent- 
agonal anal piece. Two pieces, one much smaller than the 
other, rest upon the anal plate in the type and extend but little 
above the dorsal cup. The radial plates are the largest plates 
in the body, wider than long and with an almost circular 
brachial scar each which occupies over half the width of the 
plate and directed almost horizontally. All of the plates are 
convex, being depressed along the sutures and with a clustet 
of low tubercles, running together on the infrabasals. On 
the radials, the tubercles form a semicircumference about the 
brachial scar. The tendency toward confluence of the tuber- 
cles is not wholly confined to the infrabasals but is noticed 
at the center of each basal and the anal plate, there being no 
invasion of a narrow sutural area. 
The surface of the plates is minutely granular. Test thick. 
Our species may be compared with M. and W.’s C. farleyi. 
The specific name is in honor of the discoverer Mr. Z. T. Snively 
of Wayland.

Fic. 9. Side view of the dorsal cup. 
Fic. 10. Basal view of the same specimen. 
The width of body is greater than the length. All the 
plates are convex. Column large. Infrabasals short. The 
basals are of equal length and width. The radials are heavy
