749 Nycteris cinerea (1) Galime Mad R. ford, 2700 ft., above Ruth, Trinity Co., Salis. May 26, 1933 This evening we had a remarkable flight of Hoary Bats. None have been [illegible] hitherto. They were out from early to late evening, flying higher in the early part and lower in the later part of the evening. Their flight was more relatively straight as true, more like Nycteris than Myotis. The flight this appeared like a migratory movement, so large were the numbers and so sudden the appearance of this bat. May 29, 1933 None seen this evening, nor on the 27th or 28th. This absence lends more to a migrational appearance to the flight on the 26th.
