NO. 9 MAMMALS FROM CAVES IN HAITI MILLER 9 



simple premolar immediately behind the alveolus of the canine. The 

 cavity is closely crowded between the alveolus of the canine and that of 

 the anterior root of the normal anterior premolar. Its diameter is 

 about .25 mm. In other respects the skull does not differ appreciably 

 from those collected by Dr. W. L. Abbott at Jeremie. 



Measurements. — Greatest length, 21.4; condylobasal length, 20.0; 

 zygomatic breadth, 9.0 ; breadth of braincase, 8.8 ; postorbital con- 

 striction, 4.0 ; breadth of rostrum across alveoli of canines, 3.8. 



BRACHYPHYLLA PUMILA Miller 



One skull from the steep cave near the Atalaye plantation. Its 

 measurements are as follows : greatest length, 28.0 ; condylobasal 

 length, 26.8 ; zygomatic breadth, 15.8 ; lacrimal breadth, 9.0 ; postorbital 

 constriction, 6.2; breadth of braincase, 12.2; depth of braincase at 

 middle, 9.6 ; mandible 19.0 ; maxillary toothrow (alveoli), 9.2 ; greatest 

 width of palate including molars, 10.4 ; mandibular toothrow (alveoli) , 

 10.2. This specimen and the two originally collected by Dr. W. L. 

 Abbott near Port-de-Paix shows that the Haitian Brachyphylla is 

 readily distinguishable from the large form inhabiting Porto Rico. 

 From the small Cuban B. tuina it appears to differ in slightl}- less 

 reduced size, broader rostrum and palate, and larger molars. 



ARTIBEUS JAMAICENSIS JAMAICENSIS Leach 

 Seven mandibles from the large cave near St. Michel, six skulls 

 and nine mandibles from the deep cave near the Atalaye plantation and 

 three skulls from owl pellets in the cave at Diquini. 



A large colony occupied the crooked cave in the group near the 

 Atalaye plantation. When disturbed by the noise made by workmen 

 digging in the cave floor the bats soon took refuge in small holes in 

 the roof, where they remained almost completely hidden. On one 

 occasion a half-grown young, unable to fly, fell from a roof cavity 

 to the ground near where we were excavating. As it lay helpless it 

 uttered chirping, bird-like cries. Immediately the air was filled with 

 dozens of plunging and rising adult bats behaving in the manner of a 

 flock of terns hovering over a wounded companion. Not one of them 

 actually touched the young animal, and the confusion soon subsided, 

 the adults retiring again to their holes. 



PHYLLOPS HAITIENSIS (J. A. AUen) 



Ten skulls, one left maxilla, 7 mandibles from the large cave near 

 St. Michel ; one skull from the deep cave and one mandible from the
