December 23, 1926 J. D. Stilton went back to the banana grove again today and collected Artibeus Nos, 12230, 12232, 12233 and 12235, Uroderma Nos, 12231, and 12234. I made a trip to the Encuentros mine which is about three miles west of Divisaderos on the Rio Sebo. The description given of the tunnels does not need repetition for I saw very little change. There were more Glossophaga than in the mine last year. I could see no difference in the comparative numbers of Mormoops and Chilonyceris rubiginosa. In one drive, in the same tunnel that I drove last year, I caught 1140 Mormoops and 16 Chilonyceris rubiginosa. I found both of these forms more commonly in the large vein cavities. Two Natalus were seen in association with Mormoops in the large vein cavities. No. 12236 was taken. Mormoops Nos, 12237 to 12242 inclusive we taken and Chilonyceris rubiginosa Nos, 12243 to 12248 inclusive. December 24, 25, 26, 27-19 were spent at Divisaderos
