NO. 1882. COLLECTION OF BATS FROM PANAMA— MILLER. 23 



The floor, wliich consisted of soft bat manure, was studded with 

 thousands of pecuhar knob-Uko stalagmites. Only a few bats were 

 seen in tliis cave, wliich, liowever, may well have had one or more 

 unobserved side gallciies. A long winding upwardly sloj)ing corridor 

 guarded by giant stalactites led to a small exit hole some 300 yards 

 from the mouth of the first cave. The time did not permit further 

 exploring, but it is probable that only a fraction of the cave area was 

 inspected and that it \\'ill be found to stretch for miles along the 

 course of the subterranean stream, toward the picturesque cliffs on 

 the Chagres River between Alhajuela and Vijia.
