OG the largest of the Molossidae of the region, and in general externalappearance is not very unlike the typical genus Molossus, the shortthick leathery ears projecting forward and overhanging the eyes inthe same way. The forearm measures about 59 millimeters. A large colony was found inhabiting the roof of the old policestation at Bohio. The bats remained during the day between thecorrugated iron roof and the ceiling. Looking through crevices aconsiderable number could be seen ranged in rows with their headsupward, their backs close to the iron, and their bodies lying flat onthe boards. They held on to some extent with their thumbs. Thesun was shining and the bats were panting with the almost intoler-able heat radiating from the iron. When disturbed they crawledabout with lively shuffling motions, seeking always to keep out ofsight in the crevices. They were finally dislodged by tearing off the Text Appearing After Image: Fig. 23.—Eumops glaucinus.No. 179856, U. S. Nat. Mus. About nat. size. roof. Some of them, liberated in a room from which they could notescape, flew round and round and finally hung up by their feet incorners, swinging heads downward in the usual position of batswhen at rest. The building was soon torn down and the locality isnow submerged in Gatun Lake. A specimen collected by August Busck, at Paraiso, was recordedby Miller (1912, p. 26). Specimens examined: Bohio, 14; Empire, 1; Paraiso, I. Genus MOLOSSUS Geoffroy Externally the genus Molossus is similar to Molossops, but thePanama forms are distinguishable by their smaller size in comparisonwith the only known regional representative of the latter. Theabsence of the conspicuously furred areas present on the upper sideof the wing between the forearm and fourth finger in Molossops aredistinctive. The skull differs notably from those of Molossops andEumops in the anteriorly arched braincase and high, trenchantsagittal crest sloping
