the authors. This is the more remarkable when it is remem- 
bered that the species of this genus are ordinarily confined to 
the Permian in most foreign countries. This is in keeping, 
however, with much other evidence of the youth of the Ameri- 
can Pennsylvania fauna compared to the English and European 
in general, indicating the proximity of the Kansas region to the 
point of origin of some of the higher faunas. 
seventeen or more species are peculiar to the Drum lime- 
stone. The following species are found in large numbers for 
the first time: Septopora biserialis (Swall.), Productus ne- 
braskensis Owen, Cypricardinia carbonaria Meek, Myalina 
swallowt McChes., Pseudomonotis hawni var., P. equistriata 
Beede, P. kansasensis Beede, Patellostium bellum (Keyes), Bu- 
canopsis marcouiana (Gein.) and Pseudomonotis robusta 
Beede. An interesting feature is the repetition of the second, 
fourth and fifth species in about a similar role in the Kickapoo 
limestone, and again together with the first in the Neosho 
formation. 
Stage H.—Stage E includes the Chanute shales and their 
limestone lenses and the Iola limestone. At Kansas City the 
term Chanute formation would be more appropriate than Cha- 
nute shales. The entire section of this stage is shown in the 
bluffs at the Union Station at Kansas City. Several species of 
considerable range are added during this stage: Syringopora 
multattenuata McChes., Ceriocrinus missouriensis M. and G., 
Aviculopinna americana Meek, Ceriocrinus craigu Worth., Pin- 
natopora pyriformopora Rog., Streblotrypa striatopora Rog., 
Echinocrinus triserratus Meek, Aulacorhynchus millepuncta- 
tus M. and W. and Rhabdomeson americanum Rog. are among 
the best known. 
Many species are peculiar to the rocks of this stage largely 
on account of the occurrence at Kansas City of what may be 
taken as the typical crinoid fauna of the time in the Chanute 
shale, together with a lot of vertebrates from the same forma- 
tion. The crinoid fauna is of peculiar interest in comparing 
it with that of the Howard limestone (shale between the two 
layers and near them) at Topeka. Aside from the crinoids 
and ver.ebrates there are three species of Bryozoa and 
three of Cyclus peculiar to the stage. One of the important 
features of the stage is the last appearance in the lola 
limestone of several. of the familiar species of the rocks 
below. They are Cleiothyris orbicularis (McChes.), Cryp-
