RECORD OF AMERICAN ZOOLOGY. 
BY J. S. KINGSLEY. 
(Continued from Vol. XXIV., page 548.) 
T is the intention to catalogue here in systematic order all 
papers relating to the Zoology of North America, including the 
West Indies, beginning with the year 1889. An asterisk indi- 
cates that the paper has not been seen by the recorder. Owing 
to the method of preparation it is impossible to collect in one issue 
all the papers relating to any group, but it is hoped that succeed- 
ing numbers will correct this. Authors are requested to send 
copies of their papers to J. S. Kingsley, Lincoln, Nebraska.
