and may be readily recognized by their ornamentation and 
strong, wart-like anal region. 
Codonites (Orophocrinus) whilii? (Hall.) 
Fig. 20. Side view, natural size of a specimen partly imbedded in 
chert. 
This fossil is from the base of the third horizon of the 
Lower Burlington limestone at Louisiana, Mo., and occurs 
associated with Granatocrinus exiguus, Codonites? inopinatus 
and Codaster gracillimus. It is very rare, as the writer has 
seen but two specimens of it in many years collecting. 
Granatocrinus Stella, (nov. sp.) 
Figs. 26-27-28. Dorsal, ventral and lateral views, natural size of the 
type specimen. 
In this very peculiar little blastoid the hight is scarcely 
half the breadth, giving to the natural casts almost a discoidal 
outline. Base fiat or slightly convex. Basal plates form a 
large pentagon with a width little less than the greatest width 
of the body. Ambulacra extend below and beyond the basal 
truncation and, in specimens preserving the test, extravagantly 
prolonged downward and outward like the rays of a star fish. 
The summit shows a rather large anal orifice and the cen- 
tral opening. Radials flat between the ambulacra. Deltoids 
or interradials confined to the slightly sunken summit and not 
seen on a side view. Ambulacra but little elevated above the 
flat radials. 
Most of the specimens collected are natural casts from 
chert but the figured specimen preserves the test and two of 
the rays entire. The spiracles are located as in Granatocrinus 
magnibasis with which species G. Stella is congeneric and for 
which a new generic name may have to be created. 
The ornamentation is raised lines, parallel with the plate 
sutures. 
This pretty little blastoid comes from the very base of the 
Upper Burlington limestone at Louisiana^ Mo., and occurs 
associated with Granatocrinus calycinus, Codaster grandis and 
Codaster laeviculus.
