tinctly Permian types of fossils in the Elmdale formation of 
Stage I which foreshadow the typical Permian fauna. Doc- 
tor Girty finds Bakewellia parva M. and H. from even the 
Willard shales of Stage H. 
Stage F.—The Lane shales, Allen limestone, Vilas shales, 
Stanton limestone, Le Roy shales (including Elgin sandstone), 
Kickapoo limestone, Lawrence shales and Oread limestone 
make up Stage F. 
This stage is characterized by the introduction, or special 
development, of some very important faunal elements, Chonetes 
granulifer Owen and Enteletes hemiplicata Hall and Fusulina 
spp., and the exit of nearly thirty species of the older faunules. 
Barriers were removed which allowed these species to enter, 
and, once admitted, they remained until they, the last of their 
kind, finally left the stage of existence. A species of Amblysi- 
phonella is found in the Lane shales, near the top of the Iola 
limestone, at Iola and becomes very abundant in the Allen 
limestone, as does a large species of sponge and a smaller one. 
The Amblysiphonella is found for the last time in the Oread 
limestone at Burlington. Enteletes hemiplicata Hall appears 
in the Allen limestone near Kansas City and is extremely 
abundant in the Stanton limestone at Eudora. Pinnatopora 
trilineata (Meek) becomes numerically important only in the 
_ Allen limestone, while P. multipora Rog. is not known above it. 
Chonetes granulifer Owen is added in the Allen limestone, and 
Doctor Girty records the last appearance of Chetetes mille- 
poraceous M.-E. and H. from it. 
The Kickapoo limestone records the imperfect reéstablish- 
ment of odlitic conditions in the northern part of the Kansas 
sea. The Pseudomonotis fauna is again present and, in gen- 
eral, the molluscan tendencies of the older odlitic faunule re- 
appear, but only weakly, and the faunal assemblage as a whole 
is not present. Limopteria marian White, and Fenestella 
shumardi Prout? make their first appearance in this forma- 
tion, while ten species (all pelecypods but one) are peculiar 
to it. Seven or eight species are found here for the last time. 
They include the last of the Merostomata, except Prestwichia 
danse (M. and W.), which disappears in the Lawrence shales 
above. Limopteria marian White, Edmondia nebraskensis 
(Gein.), Limopteria longispina (Cox), Pteria longa (Gein.), 
P. sulcata (Gein.) and Schizodus compressus Rog. form im- 
portant parts of no other faunule.
