NO. 9 MAMMALS FROM CAVES IN HAITI MII.LER II 



lOO, the length of this rei^ioii from front of premaxilla to posterior 

 border of foramina averages about 82 in Phyllonyctcris poeyi, while 

 in the three specimens of P. ohtusa it is only 56.6, 58. and 59.5. 

 respectively. The curve of the anterior premaxillary border of the 

 palate forms part of a circle which, if completed posteriorly, would 

 pass close behind the foramina in P. poeyi, but in P. ohtusa it would 

 be so much larger that the hinder edge of the foramina would scarcely 

 extend beyond its center. The mandible and the molars, both maxillary 

 and mandibular, do not differ a])precial)ly from those of P. pncyi. 

 Other teeth lost. 



Measurements. — Type and si)ecimen from Diquini (No. 253096) : 

 greatest length, - — , 22.2; palatal length, lo.o, 10.2; back of glenoid 

 process to front of premaxillary. 17.2, 16.8; breadth of braincase, 

 — , 10.2; postorbital constriction. 5.6. 5.4, width of palate including 

 molars, 7.2. 7.0; mandible. — . 15.4; maxillary toothrow (alveoli). 

 7.0, y.2\ mandibular toothrow (alveoli), — , 8.0. 



Specimens examined. — A skull and mandible from the crooked cave 

 near the Atalaye plantation, a skull from a cave near Port-de-Paix 

 (Dr. W. L. Abbott), and a skull from owl pellets found in the cave 

 at Diquini. 



Remarks. — Unlike its relative ErophyUa the Haitian PhyUonycteris 

 is not particularly like the Porto Rican member of its genus. As 

 Anthony figures (Mem. Amer. Mus. Nat. Hist., n. s., Vol. 2, pi. 60. 

 fig. 12) and describes the Porto Rican P. major it is a larger animal 

 with relatively small teeth; palatal length ranging from 10.6 to ii.i. 

 but with a toothrow of only 6.7 to 6.8. 



EPTESICUS HISPANIOL^ Miller 

 TADARIDA MURINA (Gray) 



One mandible of each of these small bats was collected in the large 

 cave near St. Michel. 



RODENTIA 



P>ones of native rodents representing six genera, only one of which 

 is known to have a living species, form the great mass — probabl} 

 more than 95 per cent — of all the deposits. Mingled with them are 

 the remains of the large owl, Tyto ostologa, which brought them to 

 the caves. It is easy to realize that the existence of a bird of this 

 type might depend so entirely on an abundant rodent food supply that, 

 with the gradual disappearance of the large indigenous rodents, the 

 owl must also have become extinct, leaving the caves to the small
