subgenus, Pseiidalopex, leaving in Lycahpex, of the species originally 

 referred to it, C. cmicrivonts and C. vetitlits. To Psendalopex he also 

 referred C. griseus Gray, making Psendalopex a pure synonym of Cer- 

 docyo)i, as is also Pseitdahpex of Gray, excluding C. antarcticus. 



Gray, in 1868, still further restricted Lycalopex by removing from it C. 

 cancrivonts, to form, as already stated, his new genus Tlwus, the name 

 for which being preoccupied is above replaced by Carcitiocyoii. Of the 

 four species originally included in Lycalopex two [azarce and magellanicns) 

 already belonged to Cerdocyon, and the removal of cancrivorus to Tlioiis 

 left in it C. vetulus of both Lund and Burmeister. If C. vetnliis Bur- 

 meister is not the C. vetidus Lund,^ as Mivart believed, but is referable to 

 what Mivart saw fit to name C parvidetis, C. vetulus Burmeister was really 

 nameless, and Lycalopex cannot thus take the place of EiiHotJwcyon. On 

 the other hand, Lycalopex cannot be made to replace T/ioi/s, when Gray, 

 in establishing Tlioiis, preserved Lycalopex for what he regarded as 

 another and distinct genus, to include the C. vetulus and C. fulvicaiuhts 

 of Lund.
