_Myotis californicus_, in western Washington, often occurs in company with _Myotis yumanensis_, _lucifugus_, and _volans_. In flight it cannot be distinguished from _M. yumanensis_ or _M. lucifugus_. Most of our specimens were collected over water, for these bats usually fly rather late and can be shot most easily where their reflection on the water assists the hunter in aiming. They are usually not common, one or two being taken at a single locality. This species, like _Myotis yumanensis_, seems to drink salt water. On May 9, 1936, a living specimen was caught under a loose piece of bark on a dead tree. =Myotis californicus caurinus= Miller _Vespertilio nitidus_ H. Allen, Proc. Acad. Nat. Sci.
