180 THE SCHIZOPODA. 
Finally I desire to render my sincere thanks to the authorities of the Museum 
of Comparative Zodlogy 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.
