Norrn American Inrusorta.—Dr. A. C. Stokes has done stu- 
dents of the Infusoria good service in collecting together in his “ Pre- 
liminary Contribution toward a History of the Fresh-water Infusoria 
of the United States” (Journal Trenton Nat. Hist. Soc., vol. i., pp. 
71-44, pls. xiii., 1888), an extended catalogue of all the known 
Species in the United States. Even his own papers appeared in so 
many places that it was rapidly becoming impossible to keep track 
of them all. In the present catalogue 351 species are enumerated, 
distributed as follows :—
