their range, the Hooser material loses much of its diagnostic 
value as a horizon marker. It is of great value, however, for 
purposes of foreign correlation, which Mr. Spandel has very 
earefully discussed.2“° With further studies of this sort much 
light will be thrown on the complex relationships of the fauna. 
Stage J.—Stage J includes the Cottonwood limestone, Flo- 
rena shales and the Neosho formation. There is some question 
about referring the Cottonwood limestone to this stage. The 
faunal changes between the Eskridge and the Florena shales 
may have taken place prior to the deposition of this stone. In 
the southern part of the region it seems to be quite as closely 
related to the younger as to the older formations, and for that 
reason is here included in Stage J (or Council Grove Stage). 
The principal faunal element here is an abundance of Fusu- 
line. In the northern part of the state they are never abun- 
dant after the Cottonwood limestone is passed, but farther 
south they become rather numerous in the Florena shales. 
Only a very few specimens have been seen from the Neosho 
formation, though they make up the bulk of the upper layer of 
the Cottonwood limestone. 
During the deposition of the Florena shales the sea swarmed 
with Ostracoda, especially Bairdia beedei Ulrich and Bassler, 
and its variety abrupta U. and B. Beyrichia? emaciata? U. 
and B., Beyrichia radiata U. and B., Beyrichiella bolliformis 
U. and B., Kirbya pinguis U. and B., Beyrichia haworthi U. 
and B. and Kirbya centronata U. and B. also occur in this for- 
mation, though forming a more inconspicuous’ part of the 
faunule. The last two species are peculiar to it. Productus 
semireticulatus Mort. and Bairdia seem to culminate in this 
formation, while Crania modesta W. and St. J. reaches nu- 
merical importance only in it. 
The main character of the Florena shale is the abundance 
and obesity of its brachiopod fauna. This is especially true of 
Chonetes granulifer Owen, Seminula argentea (Shep.) and 
Productus semireticulatus Mort. Along with these are numer- 
ous specimens of Derbya, Meekella striatocostata (Cox), and 
Thamniscus octonarius Ulr. 
Six species are peculiar to the Neosho formation; a palea- 
cyclid coral, a peculiar small Ceriocrinus?, an ophiuroid, Che- 
nomya maria Worth.?, Nucula beyricht V. Schaur.?, and Aclis-
