IOWA ACADEMY OP SCIENCE Vol. XXIV, 1917 
specimen on which the reddish hair on the underp.arts was re- 
placed with black, and I saw another snch specimen at Sac City. 
Flying Squirrel ( Sciuropeterus volans). A few flying, squir- 
rels were said to be found in every grove at the time of settle- 
ment (2, 3), and some are still to be found (2). 
Common Shrew ( Sorex personatus haydeni). On July 13, 
1917, I obtained a specimen of this shrew which Mr. Guy Martin 
captured in a clover field, three miles west of Sac City. It was 
identified by Mr. E. W. Nelson of the U. S. Biological Survey. 
Short-tailed Shrew ( Blarina brevicauda) . This shrew is com- 
mon in the vicinity of Wall Lake. After heavy and prolonged 
beating rains, I have often found them lying dead on our lawn. 
I have also seen domestic chickens kill them, not without fierce 
and shrill squeaking on the part of the shrew, however. Its 
ridges are more commonly found in pastures and hayfields, but 
only rarely in corn fields until after cultivation ceases. 
Prairie Mole ( Scalops aquations machrinus) . Specimen in 
the Smith collection. This species is quite common in the vi- 
cinity of Wall Lake. I have found it principally about farm 
yards, fences, pastures, and other undisturbed places. Several 
times in the spring I have found their dead bodies upon the 
surface of the ground, together with evidence that they had been 
making tunnels through the snow drifts. This evidence was in 
the form of channels in the remnants of ice left from snow- 
drifts. On one December day I found a mole crawling over the 
surface of the ground although this was frozen to a depth of two 
or three inches. At another time I heard a shrill squeaking and 
upon investigating,- found two moles fighting just below the sur- 
face. One was soon forced out upon the surface, but immedi- 
ately started to burrow under again. 
Red Bat ( Lasiurus borealis). This bat is common in the vi- 
cinity of Wall Lake. I have captured six or eight specimens 
which I identified by the aid of the North American Fauna on 
bats. I have usually found them hanging in a tree or bush a 
few feet from the ground. The first specimen I kept a record 
of was captured July 5, 1908. 
Hoary Bat ( Lasiurus cinereus). I captured a specimen of 
this bat August 23, 1908, and have seen two others of whose 
identity 1 was certain. It is rather common.
