The Mammalian Remains of the Donaldson Cave. 



Walter L. ILaii??. 



While occupying the L)on;ildsoii Fann Fellowsliip in Zoology in Indiana 

 University, the writer has liad occasion to make freiiueut trips into the 

 Donaldson Cave, situated about three miles southeast of ^litchell. Indiana. 

 On one of these trips bones of small mammals were noticed and diligent 

 collecting on that and subsequent occasions has resulted in the finding of 

 identifiable remains of 244 individuals, representing eleven species. The 

 occurrence and relative abundance of some of these species is of consider- 

 able interest and this occasion is taken to place all on record. 



The list follo\\s 



1. Didelpliis virnhiiuna Kerr. Opossum. 



A portion of one skull found on a gravel deposit in a side passage 

 leading off from tlie "big room" of the cave. 



2. Odocoilcits Virginian K-s (Boddaert). Virginia deer. 



A vertebra foimd not far from the preceding specimen has been 

 identilied for me by Mr. J. M. Gidley, Vertebrate Paleontologist 

 of the National IMuseum. as the fourth cervical of this species. 

 It was doubtless carried in, either by a flood or by some car- 

 niverous animal, in the days when deer were plentiful in In- 

 diana, and since that time has la.in undisturlied in the dark- 

 ness of the cave. 

 .3. Sijlvilaf/iis floridanus (Allen). Rabbit. 



Remains of three individuals found. 



4. PeronnjHCii.^ leitcopiis (Rafinesque). White-footed mouse.
