Allen, — Oertaia Generic and Specific JVcimes. 93 



Opossum, named D. virginiana by Kerr in IV 92. This leaves 

 of the identifiable forms included under the original D. tnai- 

 suplalis Linn, the large Opossum of Mexico, namely the Tla- 

 cuatzin of Hernandez, to which the name marsupialis must evi- 

 dently restricted. As I), karkinophar/a has obtained some cur- 

 rency for the large Opossums of northeastern South America, 

 and as D. inryiiiia.t i has been currently accepted for the Opos- 

 sum of the United States, the present ruling very little disturbs 

 the nomenclature of the groujt. The restriction of J). nHirmi- 

 piolift to the large Mexican Opossum simply takes the place of 

 DiilelpJiiK cdlifoDiIca of Bennett, which as a specific designa- 

 tion has never had much currency.*
