292 ANNUAL REPORT SMITHSONIAN INSTITUTION, 1930 



dontidae. This is composed of three genera, each with a single 

 species, as follows: Desmodus rotundus rotundus Geoffroy; D. ro- 

 tuTidus murinus Wagner; Diphylla centralis Thomas, and Diaemus 

 youngi (Jentink). 



The habits of Diaemus youngi^ appearing to be a rare species, 

 have not as yet been authentically noted. The dentition, however, 

 points to it being of similar habits to the two former sanguineous 

 species.
