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. 
Infusorians.—Ophrydium sp. Quiet, warm waters of First and Second lakes. 
Sponges.—Spongilla sp. Abundant in the shallow quiet water of inlets and 
pools of First, Second, and Third lakes. 
Bryozoans.—Cristatella magnifica. Taken from rocks along shore of First 
Lake. 
Leeches— 
Dina fervida Verrill. 
Glossyphonia complanata Linneeus. 
Placobdella picta Verrill. 
Crustaceans.—The only crustacean observed was living among sponges, an 
amphipod, specimen lost. 
Insects— 
Phryganide, various species, including Helicopsyche sp. Lary taken from 
shore rocks of First Lake. 
Biitacomorpha clavipes Fabricius. Larve dredged in Second Lake with 
Chara and Batrachium. 
Chironomus sp. Tubes containing larvee and pup common on Chara and 
Batrachium in Second Lake. 
Tanybus sp. Tubes containing larve and pupze common on Chara and 
Batrachium in Second Lake.
