_Remarks._--Those males with worn teeth seem to have a slightly longer and deeper rostrum with a larger, more inflated cranium than specimens of _S. p. navigator_ from Washington, but in other ways resemble typical _S. p. navigator_. An adult male, with slightly worn teeth, from Dezadeash Lake has sagittal and lambdoidal crests. All of the water shrews were taken in July and early August and at the edge of water in traps baited with rolled oats. None of the females had embryos. Myotis lucifugus lucifugus (LeConte) Little Brown Bat _Vespertilio lucifugus_ LeConte, McMurtrie's Cuvier, Animal Kingdom, vol. 1, appendix, p. 431, 1831.

Alcorn searched ten frame buildings in an abandoned camp on the east side of Screw Creek, for bats and found only the one bat. It was above some droppings. No droppings were found in other buildings.
