specimens were taken in the waters of Sandusky Bay, Lake Erie, 
at what is called Black Channel. Before this time specimens had 
been brought into the Ohio State University Lake Laboratory 
at intervals, but in some seasons were difficult to secure. During 
the summer of 1905 not one was brought in. In August of 1900, 
at the close of the summer session the writer was collecting 
sponges near Black Channel, when two or three specimens were

Institution for identification. Miss Mary J. Rathbun, of the 
Division of Marine Invertebrates kindly identified them as Palae¬ 
monetes exilipes, Stimpson, widely distributed through the 
eastern half of the United States excepting New England. Miss 
Rathbun also stated that this shrimp grows to be two or three
