MACROSCOPIC FAUNA OTHER THAN FISHES. 



Some aquatic or semiaquatic animals other than those belonging to 

 the plankton came under observation as the headwaters of the Con- 

 necticut River were examined. A thorough search would multiply 

 many times the number of species found. The following list enum- 

 erates all the species noted, but it does not attempt to give their com- 

 plete distribution in these waters.
