I. Introduction. 
In the summer of 1896, at the suggestion of professor E. 
H. Barbour, the writer began a study of the fossil Bryozoa 
of the state. Since that date an abundance of material, re- 
presenting over fifty species, has been collected, classified and 
described. Tliis paper is only a part of a complete unpub- 
lished report in which both new and old species are described. 
Professor Barbour, Miss Carrie A. Barbour and Messrs. W. 
H. H. Moore, and E. C. Woodruff have assisted in the col- 
lecting. The illustrations were drawn by the writer, Mr. E. O. 
Ulrich and ]\Irs. G. E. Condra. 
The writer is indebted to Messrs. E. O. Ulrich and R. S. 
Bassler for valuable assistance. Specimens sent to Mr. Ulricli 
for verification were returned with helpful notes. My es- 
pecial thanks and gratitude are due professor Barbour whose 
kind and stimulating assistance has made this publication 
possible.
