346 University Geological Survey of Kansas. 
Derbya multistriata (Meek) (=D. cymbula) are found for 
the first time, while Conularia crustula White?, Polypora nodo- 
carinata Ulr., Septopora pinnata Ulr. and Trachydomia wheel- 
ert (Swall.) are found for the last time in the Deer Creek 
limestone. The appearance of Strophalosia and Aclisina 
swallowana (Gein.) for the first time, and the final appear- 
ance of Phillipsia major Shum., Polypora submarginata Meek, 
Syringopora multattenuata McChes., Echinocrinus aculeata 
Shum., and Fenestella hexagonalis Rog., are the more notable 
characters of the Topeka limestone faunule. Amblysiphonella 
prosseri Clarke and Fistulipora carbonaria Ulr. are among the 
more important of the seven species peculiar to it. 
With the muddying of the waters of the Howardian time 
many of the characteristic species of the Kansas basin were 
smothered out, twenty-eight in all. Among them were such 
familiar forms as Squamularia perplexa (McChes.) (shown 
in chart as stopping at the Severy shale), Productus pertenuis 
Meek, P. costatus Sow., Aviculopecten carboniferus Stev., 
Campophyllum torquium Owen, Chainodictyon laxum Foerste, 
Nautilus planovolvis Shum., Naticopsis ventricosa McChes., 
Capulus parvus Swall., Worthenia tabulata Conr., Lima reti- 
fera Shum., Limopteria gibbosa (M. and W.), Ceriocrinus 
eraigii Worth., Pinnatopora pyriformipora Rog., Fenestella 
shumardi Prout, Polypora aspera Rog., and Fenestella dentata 
Rog. The culmination of Streblotrypa prisca Gabb and Horn 
was also an important feature. Yoldia subscitula M. and W., | 
Bulimorpha nitidula (M. and W.), Allorisma geinitzi Meek 
and Sphserodoma medialis (M. and W.) appear first in this 
limestone. 
The ecrinoid fauna is also interesting, since many of the 
genera found in the Chanute shales are absent and species of 
Ceriocrinus and Erisocrinus play the leading role. It should 
be remarked here that most of the crinoids are found in the 
blue clay shale between the two layers and near them. So far 
as we can see the conditions were fairly similar in the two 
localities and the faunas may be taken as being as nearly 
representative as we are apt to find. The fauna here is largely 
that of the later Coal Measures, while the Kansas City crinoids 
represent an earlier type. Among the twelve species of fos- 
sils peculiar to this limestone may be mentioned Gastrioceras 
subcavum (M. and G.), Solenocheilus collectus M. and W.?,
