SOME SHELLED RHIZOPODA OF KANSAS. 

 A PRELIMINARY REPORT.

( Contributiou from the Zoological Laboratory, No. 207.) 



THE classification of the American Protozoa has received 

 little attention until the last few years. Stokes' "A Pre- 

 liminary Contribution toward a History of the Fresh- 

 water Infusoria of the United States" and Leidy's "Fresh- 

 water Rhizopods of North America" are the only general 

 works on the subject. In 1905 Conn, in connection with the 

 Geological Survey work, made a preliminary report on the 

 "Protozoa of the Fresh Waters of Connecticut," and in 1906 

 Edmondson's "Protozoa of Iowa" made its appearance. There 

 is as yet no classification of the Protozoa of Kansas, though the 

 advantage of such a work is evident. 



It is the purpose of the zoology department of the University 

 of Kansas to begin such a classification. To this end the fol- 

 lowing paper is contributed, and I want to take this oppor- 

 tunity to express my gratitude to Miss Nadine Nowlin, who 

 directed the work.
