Quest 1948 Mormoops megalophylla May 4 ½ mi South of Mulege, 100+ ft. Baja California. Six or eight caught by cave in mountainside about ¼ mile north south of the mission at Mulege. The one specimen I put up was a male (#13). The Mormoops were associated with Leptonycteris (?) -put up by Dr. Benson, and Macrotoys californicus. Bats were in second room of cave (see journal pgs. 48 & 49 for description). June 24 Same Location. Revisited above cave this morning and found only one of this species. One Leptonycterus and about five Macrotoys californicus were captured, but the latter were released. The cave had far fewer numbers of bats in it this time, only about 50 Macrotoys californicus being seen and only one of Mormoops megalophylla and Leptonycterus each (also caught).
