10/6/1925 46 October 6, 1925- Another clear day rained during the evening. - Going by mile back and walking in many place we went over the mountain range north of Monte Mayor to the Jimertor Tunnels on Carisal Hill. The first of these tunnels was at the foot of a steep slope which was covered with dense third growth jungle. The floor of the tunnel was covered with about twelve inches of water, and was about onehundred to one hundred and twenty feet long. This place seemed to be a home for the Grizzley bats (Desmodus rotundus). There were about fifteen of these bats in the tunnel and one Brown leaf-nosed bat (Glossophaga). We caught them by holding the net at the opening and driving them into it with by taking a mining lamp and going to the face of the tunnel and driving them ahead. The second tunnel was further down the canyon but more in the open except that the opening was covered up with large weeds. There was water in this tunnel but not so deep. There were more bats here than in the other tunnel but there was only one Grizzley bat (Desmodus rotundus -) while the place alive with Brown leaf-nosed bats ( - ) also there was one Gray leaf-nosed bat.
