LETTER OF TRANSMITTAL. 
THE UNIVERSITY OF MINNESOTA, 
MINNEAPOLIS, MINN., 
November 30, 1894. 
To the President of the Board of Regents of the University of Minnesota. 
Sir: I have the honor herewith to submit to the honorable Board 
of Regents my second report as zoologist of the Geological and 
Naturai History Survey of Minnesota, together with a report on the 
Entomostraca of Minnesota by Mr. C. L. Herrick, a graduate of the 
University and professor of Biology at Denison University. The 
report on one group of the Entomostraca, that of the Ostracoda, was 
written by C. H. Turner, professor of Natural Science at Clark Uni- 
versity, Atlanta, Ga. These gentlemen have given their services to 
the survey without charge, having asked for and received barely 
enough to cover their expenses. 
Very respectfully, your obedient servant, 
HENRY F. NACHTRIEB, 
State Zoologist.
