Our aim is to bring up to date the list of kinds of bats actually knownfrom Barro Colorado Island, Panamá. In 1952 Samuel T. Dickenson,Marguerite Schultz, George P. Young, and E. Raymond Hall spent the first17 days of April (except Mrs. Schultz who left on April 8) on BarroColorado Island. On eight evenings a silk net, 30 feet long and 7 feethigh with a ¾-inch mesh, was stretched in an open place to interceptbats. On the first five nights it was stretched in the laboratoryclearing. On April 6 the net was erected in the forest across theBarbara Lathrop Trail 25 feet past its entrance; on the 7th and 8th thenet was placed across the Snyder-Molino Trail at the Termite Cemetery,150 yards southwest of the new (built in 1952) laboratory.
William B. Jackson was on the island from January 30 to June 6, 1952, asa member of a group from the American Museum of Natural History. On May4 he set the bat net across Allee Creek at the beginning of the BarbaraLathrop Trail, and from May 5 to 27 he set the net in the TermiteCemetery where it was mounted between two small trees with its loweredge approximately 5 feet above the ground. Unless otherwise stated,specimens were caught in this net.
On Barro Colorado Island one aim is to preserve the biota and naturalconditions with as little interference from man as possible.Consequently most of the bats captured were released after beingwing-banded by Jackson with U.S. Fish and Wildlife Service bat bands;but an attempt was made, with the permission of Mr. James Zetek,Resident Custodian of the Canal Zone Biological Area administeredthrough the Smithsonian Institution, to save one or a few specimens ofeach species for positive identification. Catalogue numbers are of theUniversity of Kansas, Museum of Natural History, unless otherwiseindicated. We are obliged to Mr. Colin C. Sanborn and Mr. Robert J.Russell for checking our identifications of the specimens. Assistancewith field work is acknowledged from the Kansas University EndowmentAssociation, the United States Navy, Office of Naval Research, throughcontract No. NR–161–791, and Mr. James Zetek.
Six species of bats were recorded from Barro Colorado Island byProfessor Robert K. Enders in his "Mammalian Life Histories from BarroColorado Island, Panamá" (Bull. Mus. Comp. Zool., at Harvard College,78: 383–502, 5 pls., October, 1935). With his list as a starting placewe can offer a revised list as follows:
Saccopteryx bilineata (Temminck).—Nos. 45061, 45062, 45097, and 402 and404 of Jackson. No
