Order I Marsuplalja. 



Fam. I. I>id('l|)liyidae. 



1. Didelphys. 



I. Didelphys virginiana. 



After the sheet containing this species had passed through the 

 press, Dr. J. A. Allen published a paper in the Bulletin of the Am. 

 Mus. Nat. History, October 12, 1900, entitled, a "Note on the Gen- 

 eric Names Dihei.phis and Phil.^nder," in which he endeavors to 

 show b\- elimination, etc., that the proper name for the Virginia 

 Opossum should be marsupialis, Linn., and not virglniana, Kerr. On 

 this point also consult J. A. G. Rehn, American Naturalist, igoo, 

 .\xiv, pp. 575-578, and Alston, Biol. Centr. Amer., i, p. 196 (foot 

 note), where exactly the opposite decision has been reached.
