star-like; the subradials are very large and longer than wide, 
which produces the great length or pyramidal form of the calyx; 
four of the plates are hexagonal and one heptagonal ; four of the 
first radials are pentagonal, wider than long and truncated above 
the full width of the plates; the one on the right of the azygous 
side is possibly hexagonal, as one side may be slightly truncated 
by the second azygous plate; the upper face of the first radials 
bears a furrow extending from one angle of the plates to another, 
behind which there is a narrow, crenulated ridge, on which the 
second radials or brachial pieces articulated. The first azygous 
plate is irregularly quadrangular and rests obliquely in a notch on 
the top of a subradial and below the under sloping side of the first 
radial on the right, but it does not reach the second subradial. 
The second azygous plate is injured in our specimen, but it 
appears to have slightly truncated one angle of the first azygous 
plate, and the two abutting first radials at the top of the calyx. 
Found in the Upper Coal Measures, at Kansas City, Mo., and 
now in the collection of Wm. F. E. Gurley. The specific name 
is in honor of Mr. E. Butts, of Kansas City, who has done a great 
deal to make known the Natural History of that vicinity. 
ULOCRINUS KANSASENSIS, N. Sp. 47 
Plate I., Fig. 7, azygous side view ; Fig. 8, outline view regular side ; 
Fig. 9, top view of calyx to show the prolongation of the first radials 
and contracted opening of the calyx; Fig. 10, basal view. 
The calyx of this species is somewhat half-globular in form, 
though the height is more than two-thirds the width at the top; 
the plates are moderately thick and quite convex externally, so as 
to place the sutures in wave-like depressions quite as deep as they - 
are in U. buttsi; sutures distinct, but the plates are not beveled; 
surface granulous. 
The basals form an equal-sided convex pentagon, with a central 
depression for the star-shaped columnar canal; the subradials are 
each about the size of the united basals, a little wider than high, 
all pentagonal and nearly equal-sided except the hexagonal plate 
supporting the lower face of the azygous plate. The first radiais 
are pentagonal, except the one on the left of the azygous plates, 
which becomes hexagonal by the very slight truncation made by
