142 KANSAS UNIVERSITY SCIENCE BULLETIN. 



master fauna, as here illustrated, were sent Mr. T. W. 

 Stanton, who stated that thej were unmistakably Paleozoic. 



It was unfortunate that the entire type collection (except 

 two specimens) of the Whitehorse sandstone as figured in 

 the first bulletin of the Oklahoma survey was destroyed in 

 the fire which consumed Science hall at the University of 

 Oklahoma. In order that there might be specimens for com- 

 parison as near the types as possible, and collected from the 

 type locality, I have figured here a new set, which are now 

 in the museum of the University of Kansas. 



The fossils upon which this paper is based were collected 

 by the writer in the summer of 1904. Those from the White- 

 horse sandstone were taken from Whitehorse spring, some 

 two miles or more southeast of Whitehorse post-office, and 

 eighteen miles due west of Alva, Okla. They were taken 

 from the top of the hill Just west of the spring. Those from 

 the Quartermaster division are from the sandstone rolled 

 down on the west side of the "Dozier mountains," east of 

 Mr. Caperton's place (then the Dozier post-office), fifteen 

 miles south or southwest of Shamrock, in the Panhandle of 

 Texas. 



The faunas are somewhat heterogeneous as to origin. Some 

 of the species seem to be directly derived from the Kansas 

 Permian or Pennsylvaniau, while others, as pointed out in 

 the discussion of the species, are derived from the European 

 Permian, especially that of Russia. There seems to be com- 

 paratively little resemblance to the Indian or Chinese forms. 

 The fossils described as Dielasma schacherti Beede seem to 

 have their closest allies in the Productus limestone of India, 

 the only species, perhaps, with pronounced Indian affinities. 



The following fossils have decided American affinities and 

 may be the progeny of the fossils of the older rocks of the 

 western Mississippi valley. These species are : Pseudomo- 

 notis, Solenomya, two species of Edmondia (perhaps) , il/^a - 

 Una, Sch'izodas (two species), Avicdopecten (two species), 

 Pleurophorus , Pleurotomaria agnostica, Trepospira haiuorthi 

 (has affinities both in American and in Kulogory, Russia), 

 Loxonema, Orthoiiema (two s'pecies) , Bulimorpha, and Stropho- 

 styluK permianus. Those of foreign affinities are : The Cyrto-
