New Missouri Criiioids, Etc. — Rowley. 67 
bulacra are rather wide for a Granatocrinus, and, together 
with the radial Hps form five elevated and prominent ridges. 
There are eight spiracles and a rather large anal opening. 
The plates are all ornamented by fine rows of granules. 
The general outline of this fossil is somewhat similar to 
Granatocrinus pisum of the Lower Burlington but has much 
larger interradials and much shorter radials. broader am- 
bulacra, more globose shape and is much smaller in size. 
This little fossil occurs in the basal layer of the Upper Bur- 
lington limestone at Louisiana, Mo., associated with Granato- 
crinus? magnibasis, Schizoblastus sayi, Codaster grandis and 
Codaster laeviculus. 
It is the smallest blastoid from the Burlington. 
Granatocrinus aplatus (Rowley & Hare.) 
Fig. 15. A well preserved specimen enlarged to two diameters to 
show the strong tooth-like granules in parrallel rows, side view. 
This fossil was figured and described in the August, 189 1, 
number of the Kansas City Scientist. It occurs in the brown 
earthy parting just above the "White Ledge," Lower Bur- 
lington limestone, Louisiana, Mo. It is associated with 
Agaricocrinus -planoconvexus and is scarcely larger than 
Granatocrinus calycinus. 
Codonites? inopinaius 1 Rowley &• Hare.) 
Fig. 18. Side view of a specimen, two diameters. 
This blastoid was figured and described in the Kansas 
City Scientist for July, 1899, and as but few specimens have 
been collected since then, little more is known of its relations. 
It may prove to belong to some other genus than Codonites 
(Orophocrinus). Nothing is known of the spiracles, but the 
ornamentation is that of the Codaster group. 
Fig. 19. Side view, two diameters, of a blastoid from the 
top of the 4th division of the Lower Burlington limestone at 
Louisiana, Mo., associated with Granatocrinus aplatus. It 
seems to be closely allied to Codonites? inopinatus in orna- 
mentation and general surface features, but differs in shape 
and the basal region. 
In its fiat base and general outline it is allied to Granato- 
crinus aplatus. These three forms are probably congeneric
