Genus Cuniculus. 



Cun ifiilus Brisson, Regnum Anim., 1762, p. 98. Type [Cuniculus] 

 paca Brisson. 



Mr. Hollister in the Proceedings of the Biological Society of Wash- 

 ington, Vol. XXVI, 1913, p. 79, calls attention to this genus and claims 

 that the type could not be fixed by elimination, as was done by Dr. 

 C. H. Mcrriam, who made Cuniculus alactaga (Olivier) 1800, the type, 

 because Cuniculus cauda longissima Brisson which = C. alactaga 

 (Olivier) was placed in brackets as doubtfully referred to the genus, 

 and according to Article 30 of the International Code this makes it 

 not permissable, and therefore the type must be chosen by selection. 

 He therefore makes [Cuniculus} paca Brisson the type and accordingly 

 (.'unicidus supercedes Agouti Lacepedc, 1799. 



Cuniculus paca nelsoni (Goldman).
