52. Umbra limi {Kirtland). Mud Minnow.- — A number of mud minnows 

 were shipped in wet moss from Caledonia, N. Y., April 10, 1896, by James Annin, 

 Jr., and nearly all were alive at the end of the twelve hours' journey. The species 

 has not proved hardy, either in balanced tanks or in running water, notwithstanding 

 its reputation as a fish that can endure alternate freezing and thawing without 

 permanent injury.

 1895, Mr. James Annin, Jr., sent from Rockland, N. Y., a small pickerel which had

 unites with the Delaware. Subsequently two examples were forwarded alive from the 

 same place, and one of them is still living in the Aquarium. The following notes and
