tacanthia compacta W. and St. J., Strophalosia spondyli- 
formis W. and St. J., Michelinia eugenex White, Fenestella 
—qwortheni Ulr., Conocardium parrishit Worth., Cyclus packardt 
Rog., Lima krotowi Stuck.? and Cypridella sp. Three species, 
Aviculopecten rectilaterartus Cox, Yoldia knoxensis McChes. 
and Ephippoceras divisum (W. and St. J.), are unknown above 
the Chanute shales. 
Spiriferina kentuckiensis (Shum.) culminates in. the Iola 
limestone. Cleiothyris orbicularis (McChes.), Cryptacanthia 
compacta W. and St. J. (at Chanute), Chainodictyon laxum 
Foerste, Fenestella remota Foerste and Cyclus communis Rog. 
reach numerical importance only in the Iola limestone, while 
the same is true for the following species in the Chanute 
shales: Campophyllum torquium Owen, Conularia crustula 
White, Schizodus harii Miller, and three species of crinoids. 
The following species first form important elements of the 
fauna in the Chanute shales: Rhipidomella pecosi (Marc.), 
Rhombopora lepidodendroidea Meek, Phialocrinus magnificus 
(M. and G.), Hrisocrinus typus M. and W., and Ceriocrinus 
hemisphericus. (Shum.), while the same is true for Meekella 
striaticostata (Cox) in the Iola. 
SERIES III. 
In Series III occurs a fourth faunal incursion, the fossils of 
which color all the remaining faunules of the.Coal Measures of 
Kansas. 
This series is composed of three stages, F, G and H, which 
comprise a large part of the Kansas Coal Measures. As here 
defined it extends from the top of the Iola limestone to the top 
of the Americus limestone. : 
The most important elements of the fauna introduced or 
especially developed are Chonetes granulifer Owen,?” species 
of Fusulia, and Enteletes hemiplicata Hall. Fusulina may 
have been introduced earlier in the northern part of the section, 
but attained no prominence until the Oread limestone is 
reached, when it swarmed the clearer seas until the close of 
the time represented by the top of the Cottonwood limestone 
and Florena shales. A few stragglers remained until well into 
the Permian. 
The top of the Americus limestone is chosen as the top of 
this series on account of the thinning of the ranks of the 
Coal Measures species, and especially the introduction of dis- 
275. Ante.
