Cyathocrinus? ovalis n. sp. 
Platk XVI. KiG. 13, 14.. 15. 16 X 2. 
This species is almost certainly not Cyathocrinus. Our ma- 
terial consists of four, small oval bodies, all of which are 
figfured on the plate. The stem scar is minute. The under 
basals are five in number, quadrang'ular and elongate forming 
a cup of considerable depth, llie basals are five, elongate and 
hexagonal. The third ring of plates consists of five radials 
and an anal interradial of somewhat smaller size than the ra- 
dials. The plates of this third ring are a little broader than 
long. 
The diameter of the calyx through the middle of the basals 
is much the greatest lateral diameter, the radials tucking in 
toward the arm region and thus giving an oval fomi to the 
calyx. All of die plates are smooth and rather heavy (thick). 
The scar for the arm base is nearly the full width of the 
radial. Thcbasals are considerably convex about their centers, 
giving a pentagonal outline, in an end view of the body. See 
figures 13 and 15. This lobcd character even extends to the 
under basals but less so than in the basals. 
Horizon and locality same as tlic last. 
Lecanocrinus hemisphericus, n. sp. 
Plate XVI. Kics. 17, 18, 19 X 2. 
The excavation for the stem base is small and shallow. 
The underbasals form a flat pentagon around the basal 
excavation and are small and 3 in number. The five basals 
are large, as broad as long and three of them pentagonal while 
two are hexagonal. The radials are five in number, broader 
.than long and pentagonal in outline. The ann base occupied 
the entire width of the upper radial edge. Lying between 
the upper sloping edges of two adjoining radials and the lower 
edges of a radial and second anal piece is a small ciuadrangular 
first anal. The second anal lies between two radials, the fir^ 
anal and the upper sloping edge of a basal and extends a little 
above the top of the radials.
