Acknowledgments are due Professor Vernon L. Kellogg, 

 Professor Lawrence Burner, Dr. L. O. Howard, and Dr. D. K. 

 Salmon, for material. My thanks are especially due Professor 

 Herbert Osborn of the Ohio State University, under whom the 

 work was done and who has offered valuable suggestions in the 

 course of the work. The private collection of Professor Osborn, 

 which embraces nearly all the species considered in this paper 

 was put at the disposal of the writer. 



The literature of the group is not large, but I append only the 

 more important papers from the point of view of the worker in 

 North America.
