University of Minnesota, 

 December, 1910. 



To The President of the Board of Regents of the University of Minne- 

 sota . 



Sir: — I herewith submit to the honorable Heard of Regents the 

 manuscript of a report on The Leeches of Minnesota with the recom- 

 mendation that it be published and distributed. 



The general part of the report was written by myself. The 



il paper on Placobdella pediculata, a new species parasitic on 



one of our {<><><] fishes, was prepared by Dr. E. E. Hemingway 



while pursuing graduate studies in the Department <A Animal 



Bi( 'logy. 



The systematic part of the report is based on the material and 

 notes collected by the Zoological Survey in Minnesota and was pre- 

 pared by Dr. J. Percy Moore, an American authority on leeches. 



The report constitutes "Zoological Series, No. V" of the re- 

 ports of the Zoologist of the Geological and Natural History Sur- 



Very respectfully, 



Henry F. Xachtrieb. 

 Zoologist of the Survey.
