11/4/1925 63 November 4, 1925- With the aid of Van and a mooa I collected with the net again at Monte Cristo. We drove the bats ahead of us by knocking them down as they attempted to pass. We set the net near a small stoke and made a drive, but all the bats flew up into the stoke and the was empty. A drive in the stoke netted about fifty bats, two of which were Grizley bats and two were Gray leaf-nosed bats. The others were Brown leaf-nosed bats and Yellow leaf- nosed bats, with the former the most numerous. We made another set farther back for a second drive in the main tunnel. While Van was making the drive he picked my second Franz Joseph bat from the perpendicular wall. This drive netted over fourhundred Brown leaf-nosed bats and Yellow leaf-nosed bats, some of the Yellow leaf-nosed bats were shedding. I selected a series showing the change in pelage but most of them escaped. The best specimen I have to show that change is no. 10667. The juvenile bats were just leaving their mothers. We saw several hanging from the roof of the tunnel. November 5, 1925- Left for San Salvador in the afternoo
