NO. 5 MAMMALS OF PANAMA — GOLDMAN 195 



tance west of the old cathedral tower and found a large colony of 

 H. p. aztecwm suspended in masses from the ceiling. These bats 

 shared the cellar with a smaller colony of Glossophaga s. leachii and 

 a few individuals of Macrophyllum macrophyllum, which on being 

 disturbed became mingled and fluttered close about us squeaking 

 incessantly. When we remained quiet a few minutes many of the 

 bats resumed their resting places, quietly attaching themselves only 

 a few feet away. The short-tailed bats clung with heads twisting 

 about, watchful eyes upon us, and ears trembling or turning nervously 

 this way and that. 



Another large colony was located in an old powder house on the 

 bank of the Cascajal River about five miles above Porto Bello. Here 

 the bats hung in apparently solid clusters from the ceiling of a half- 

 darkened room. 



At Bohio a few were detected clinging heads downward in half- 

 darkness along the ridge pole of an abandoned palm-thatched house. 

 When the door was opened and more light admitted they worked 

 their way along the pole by short shuffling steps, into a darker corner 

 where several disappeared in a crevice. 



In the Chilibrillo caves near Alhajuela, whence a specimen has 

 been recorded by Miller (191 2, p. 25), a few were found by me 

 roosting in the total darkness of the same large interior chamber 

 occupied by a huge colony of Phyllostomns hastatus panamensis, but 

 they were restricted to shallow cavities in the lower side walls while 

 the Phyllostomns was massed on the walls and roof above them. 

 Anthony (1916, p. 374), however, lists this form as the "most 

 abundant bat of the caves." Besides the Rio Chilibrillo specimen he 

 records specimens from El Real, Tacarcuna and Tapalisa. 



These bats were clustered in shallow crevices of two small caves 

 in the bluff forming the coast line a short distance west of the Pacific 

 entrance to the Panama Canal at Balboa. One of these caves was 

 also inhabited by Phyllostomns h. panamensis and Glossophaga s. 

 leachii, and the other by Glossophaga s. leachii and Saccopteryx 

 bilineata. 



My quarters in an old French building at Empire were shared 

 with these bats, numbers of which seemed to come tumbling out of 

 crevices in the upper story just at dusk every evening. Near the 

 same locality a few spent the day attached so that their bodies hung 

 free in a rather well-lighted place under a railroad bridge. 



They are common in most of the caves and old tunnels in the 

 vicinity of the Darien gold mines at Cana; a limestone cave close to
