8 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 8l 



Two mandibles : articular process to front of nii, 9.0 and 8.8 ; depth 

 through coronoid process, 4.8 and 4.6 ; four molariform teeth (alveoli), 

 5.2 and 5.2. 



Specimens exauiined. — Anterior portion of skull, i (type) ; median 

 portion of skull (rostrum broken away at level of pin*), i ; mandibles, 

 2 ; humerus, i . 



Remarks. — In their extremely small size the specimens which I 

 refer to Nesophontes zamicrus are sharply set off from all the other 

 material which I have examined. In the type and one mandible the 

 teeth are just beginning to wear ; in the second skull and second jaw 

 the process is distinctly more advanced. The series of N. hypomicnis 

 includes individuals representing exactly the same stages but showing 

 no approach to the diminutive size of the smallest animal. 



CHIROPTERA 



Many bones of bats occur in the deposits. While some of these 

 must have come from individuals which inhabited the caves and died 

 there, most of them were probably dropped in owl pellets. The species 

 are all, with one exception, known to be present inhabitants of the 

 island. The one exception is a local form of a genus not hitherto 

 found living elsewhere than in Cuba. There is no reason to suppose 

 that it is extinct in llispaniola. 



CHILONYCTERIS PARNELLII PUSILLUS G. M. Allen 



( )ne skull from owl pellets in the cave at Diquini. 



MORMOOPS BLAINVILLII CINNAMOMEA (Gundlach) 



Three skulls from the larger cave near St. Michel. All in superficial 

 (le])()sit. one of them in a fresh owl pellet. 



MACROTUS WATERHOUSII WATERHOUSII Gray 



Three skulls and five mandibles from the large cave near St. Michel. 

 ( )ne mandible from the small cave. All in su])erficial (le])()sits. Four 

 skulls from owl ])ellets in the cave at l)i<|uini. 



MONOPHYLLUS CUBANUS FERREUS Miller 



A skull, lacking all the teeth except ni^ right and pni^ and ni^ left, 

 was found among the owl pellet material from the cave at Diquini. 



This specimen is unique among the many skulls of Monophyllus 

 which I have examined in possessing the well-developed alveolus of a
