96 Bangs — A New Murine Opossomfrom Margarita Island. 



Remarks. — This insular murine opossum, which I have named in honor 

 of its discoverer, may be readily distinguished from M. murvna by its 

 much paler, more yellow color and smaller ear. With M. murina mexi- 

 cana, M. robinsoni agrees in having the middle of the face back to the 

 eyes decidedly paler than the rest of the upper parts and in having 

 small ears. It differs from ^[. mexicana quite as much in color as it does 

 from true murina, and can be told at a glance from either.
