ECOLOGICAL NOTES ON THE CLADOCERA AND 
COPEPODA OF AUGUSTA, GEORGIA, WITH 
DESCRIPTIONS OF NEW OR LITTLE 
KNOWN SPECIES.* 
C. H. Turner. 
This communication is but a fragment of what was 
planned to be an exhaustive ecological study of the Clado- 
cera and Copepoda of Augusta, Georgia. The various 
ponds and other bodies of water were visited at regular 
intervals, a careful record made of the temperature of the 
water and the condition of the body of water, and a collec- 
tion made with a Birge dredge. These collections were 
‘taken to my laboratory and worked over at once. The 
species were identified and measured and, usually, a rec- 
ord made of other small animals that were collected at the 
same time. When this work had been in progress for a 
little more than one year, it was suddenly terminated be- 
cause I then left Augusta to reside, permanently, in an- 
other part of the country. Partly as the result of ravages 
of mice and partly because, as the work progressed, my 
ideas as to what measurements were essential underwent 
a change, the records are not so complete as I would like. 
However, since it will be impossible for me to complete 
the work; and since so little has been published on the 
ecology of the American entomostraca, I have thought 
it best to publish the data that I have. 
Augusta, Georgia, is situated on the fall line separating 
the Piedmont Plateau from the Atlantic Coastal Plain. 
At this point, the level, sandy plain is dotted with numer- 
ous artificial ponds. These ponds, which have been exca- 
vated by the numerous brick-yards of the locality, vary 
in extent from a few square yards to several acres. There 
are also a few creeks, which empty into the Savannah
