180 THE SCHIZOPODA. 



Finally I desire to render my sincere thanks to the authorities of the Museum 

 of Comparative Zoology for their friendliness, and especially for allowing me 

 to employ my two very able countrymen, Mr. T. N. Moller, the engraver, and 

 Mr. J. Bech, the copper-plate printer, for the reproduction of my drawings. 



Copenhagen, Sept. 18, 1911.
