THIRTEENTH REPORT. 
third, which is the outlet for the other two, is commonly known as 
Parker Lake. 
Collecting was carried on principally about Diamond and Mud Lakes, 
but one trip was also made to Goose Lake, which lies about three miles 
west of the Mud Lakes and is drained by a ditch which empties into 
Ditch Lake. Special attention was given to the amphibian and rep- 
tilian fauna although other forms were also collected. The Mud Lakes 
were especially rich in both these groups as was to be expected from 
the character of the lakes themselves and from the surrounding country. 
Diamond Lake was not rich in either amphibians or reptiles except in 
Turtle Bay. We found several species of turtles there but were partic- 
ularly impressed bv the large number and the size of the soft shells. 
It may be worth while to mention that we had the best of success 
in capturing turtles by using a turtle net with a two-inch mesh. Set in 
a favorable situation this net would capture as many as twenty speci- 
mens in one day. 
«/ 
Two hundred and twenty-nine specimens representing eight species of 
amphibians, six species of snakes and seven species of turtles were 
obtained. This gives a fairly good knowledge of the fauna of the region, 
although there are of course, a number of other species there that were 
not. found. The forms not represented in the collection must, however, 
be rare.
