of Kansas.

INTRODUCTION. 



IN connection with a movement which was begun in the Uni-

 Protozoa, I have undertaken to draw and classify some of the 

 common species of Infusoria occurring in the state. Another 

 portion of this survey, Shelled Rhizopods of Kansas, by Miss 

 Regina Woodruff (to be published in the Kansas Science Bul- 

 letin) , is, at the time of this writing, in the publishers' hands. 

 These reports will be followed by others upon the other classes 

 of Protozoa, or upon as yet untouched members of the classes 

 already undertaken. As it was not intended that this survey, 

 or any very considerable portion of it, should be the work of 

 one student, and as at present time will not permit me to carry 

 my work further, it was thought best for me to publish this 

 preliminary report now. 



The class upon which I have undertaken this work is a large 

 one, and it is self-evident that I have made no very thorough 

 survey of the field. On the other hand, I am confident that, 

 during even the short time in which I have been engaged in 

 this task, I have been compelled by lack of time to pass by fully 

 half of the species of Infusoria that have come under my
