Family CHINCHILLID.-E.i 



Genus Boromys G. S. Miller. 



2. Boromys torrei Allen. 



Five specimens (Nos. 3938—3942), including skulls and portions of 

 skulls, are referred to this genus. The specimens are placed with 

 Boromys because the crania have the supplemental groove at the base 

 of the antorbital foramen, which according to Dr. Miller is the chief 

 cranial character distinguishing Boromys from Brotomys and Homop- 

 somys} The two latter genera have not this excavated groove of the 

 floor of the orbital process. In size the specimens appear to agree 

 best with B. torrei. 



Family MURIDyE. 



Genus Epimys Trouessart. 



3. Epimys alexandrinus Is. Geoff roy. 



Four lower jaws, Nos. 3943-3946, were compared very carefully 

 by Mr. H. E. Anthony, of the American Museum, and the writer. 

 That the specimens belong to this murine genus there can be no doubt. 

 These rami were not incrusted with lime, a fact of interest in connec- 

 tion with the probable age of this cave material. 



Order INSECTIVORA. 



Family NESOPHONTID^ Anthony 



Genus Nesophontes Anthony. 



4. Nesophontes micrus Allen. 



This genus and species is represented by two specimens, a poorly 

 preserved skull. No. 3934, and a mandibular ramus. No. 3935. Noth- 

 ing can be added to the complete description given by Anthony^ 

 based upon the material representing this new family, which has been 

 collected and is preserved in the American Museum of Natural His- 

 tory, where the author of the genus is engaged in systematically 

 studying it.
