206 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 69 



A colony, comprising 50 or more of these bats, was located in a 

 shallow recess in the side of the high rock forming the center of the 

 islet known as San Jose Rock in the Bay of Panama. W. H. Osgood 

 and I visited the place together and obtained specimens, a part of 

 which are now in the Field Museum of Natural History. The bats 

 were suspended in crevices. 



At Gatun several were caught in traps placed about a bunch of 

 ripening bananas that had been left uncut in an old field, and to which 

 the bats came to feed at night. At the same locality a single indi- 

 vidual was found clinging within a curled fragment of dead banana 

 leaf which still adhered to the plant at a point about six feet from 

 the ground. The colors of the bat blended well with those of the 

 leaf. Several were dislodged by firing into cavities in the arch of 

 the natural bridge over the Rio del Puente a few miles north of 

 Alhajuela, but one only was secured as a specimen. 



A specimen obtained by W. W. Brown, Jr., at Bugaba, Chiriqui, 

 was listed by Bangs (1902, p. 50) as Artibeus intermedins. Under 

 the same name, Bangs (1906, p. 213) recorded an individual taken by 

 the same collector at Calidonia (near Panama). The specimen 

 from Bugaba, measuring jj millimeters in length of forearm, was 

 subsequently referred by G. M. Allen (1908, p. 42) to Artibeus 

 palmarum, and Knud Andersen (/. c.) in the same year recorded 

 material from the same locality as subspecies palmarum. Miller 

 (1912, p. 26) assigned to A. j. jamaicensis three specimens collected 

 by August Busck on Taboga Island. 



An interesting and rather detailed account of the habits of this 

 bat, as observed by W. Osburn in Jamaica, was published many 

 years ago. 1 Osburn found them inhabiting caves in great numbers. 

 While they sometimes lived in places from which the light was 

 wholly excluded, they particularly haunted the entrances of caves, 

 or caves of shallow depth, which led him to remark that " it certainly 

 does not seem such a lover of darkness as the generality of the 

 family." He also found them " clustering under the fronds of the 

 cocoanut palm, so thickly and in such numbers that at a single shot I 

 brought down twenty-two, while many flew off and took refuge in 

 neighboring trees."
