First I'adials pentagonal, once and a If 
as wide as long and supi)Oi'ting abo- e on 
their longest sides the second ra«:ials, 
four of wdiich latter are pentagonal and 
but little wider than long, wdiile the 
anterior one is hexagonal, truncate above 
and fully as long as wide. On the upper 
sloping sides of the second radials of the 
four rays, occurs thr first bifurcation. 
On the second limb of the right posterior 
ra}^ the second bifurcation occurs on the 
eighth joint above the first bifurcating 
plate. Of tli(^ ri^ht aii1ei'i')r ia\' the 
first limb bifui-cat'>s on the sixth, w liiN; 
the, sccoiid does eo on the eightli joint. On 
the left anlerioi- ray both limbs give 
their secoad biftrcation on tlie sixth 
l)iece above the second radial. 'i'lie 
greatei- pai't of the left posterioi- ray. and 
the lii'st limb of the I'ight posterior I'ay, 
as well as the eniire anal side, of the 
specimen is hidden by the suri'onnding' 
matrix. 
The anterior jay gives the first bifur- 
cation on the fifth pi'imar}^ I'adial, the 
second division remaining simple abo\e, 
w hile the first has its second bifurcation 
on the ninth joint above the first axillary 
plate. The arms are simple above the 
second bifurcations in all the I'ays. If 
both limbs of the left and the first limb 
of the right posterior rays bifurcate, as 
seems certain, there are ninetc( u ficc 
arms. The axilliary plates sliijn 'y node 
like. Arms almost entire and clos(dy fit- 
ting, laterally so as to hide the ven'i-al 
tube and pinnies. ^SiuTace w i i iiont o;iia-

Se\'ERAL of the members of the Kansas 
City Academy spent, the 4th at the Lansing, 
Ivan, coal shaft and were well repaid in 
fossil ferns. Many of them being a bright 
green color and looking more like living than 
fossil ferns. Mr. S. J. Hare of the Academy 
has a few of these ferns for excharge.
