second is crowded quite out of the tooth row on lingual side. In C. 

 hoothl the first premolar is separated from the third hy a distinct 

 interval, in which lies the slightly displaced second. Otherwise the 

 two species appear to be closely similar. For measurements see table, 

 page 343. 



Field notes. — Four specimens were obtained at the mouth of the cave 

 near Baracoa, described under the next species. They did not emerge 

 until well after dark, and none were captured while anj^ trace of day- 

 light remained. — W. Palmer. 



CHILONYCTERIS MACLEAYII Gray.

Eight (6 skins) from Guanajay and Aft}' (6 skins) from Baracoa. 



In both series, as shown b}' the table of measurements (page 343), a 

 larger and smaller form may be distinguished, the diflerences between 

 which are fairly constant and quite independent of age and sex. Mr. 

 Oldlield Thomas, who kindly compared some of Mr. Palmer's skins 

 with the type in the British Museum, writes me that the name was 

 originally based on a large specimen. 



Field notes. — At Guanajay this was evidently a rare species. We 

 found it in only one locality, a deep, damp cave in Guanajay Moun- 

 tain, where it lived in company with thousands of PJiyllonycteris poeyi. 

 The white bat was somewhat readily captured with a dip net, and 

 occasionally, but rarely, we secured a specimen of the smaller animal. 



A few miles east of Baracoa, on a broad, well-wooded hill, is a hole 

 in the porous limestone some 8 feet in diameter and 20 in depth. At 

 the bottom, on one side, is the opening to a cave which extends an 

 unknown distance, as I could find no one who had ever explored it. 

 At the time of my visits, late on two afternoons, a slight colunm of 

 mist was rising from the openings, showing that it was a damp cave 

 similar to the one visited at Guanajay. Leading to the mouth of the 

 cave is an irregular trough in the surface of the rock. This extends 

 some distance back into the woods, and shows that the cave furnishes 

 the natural drainage for the immediate region. The people living 

 near knew of the existence of three kinds of bats in great abundance 

 in this cave. Armed with an ordinary butterfly net, during two even- 

 ings 1 was able to secure no less than 142 bats, representing six 

 species {Chilonatahts micropus, Mormoops cinnamomea, Ohilonycteris 

 hoothi.^ 0. macleayii, Monaphyllus cuhanus, and Phyllonycteris poeyi)., 

 as they emerged from the perpendicular opening. Before dark, while 

 there was still light enough to see distinctly, the small CMlonycteris 

 began to come out, at first singly or a few at a time, often hesitating 

 and returning below again for another effort, then in greater num-
