Mr. Hollister made this animal a subspecies of L. pygerythra. but 

 it would seem that its coloring and the black chin would give it more 

 properly a place between L. rubella and L. centralis. The general 

 hue of the pelage, especially on the dorsal region, is much too dark 

 for L. pygerythra, in fact it is not of the same character, but is much 

 nearer the more tawny hue of L. rubella ; and its black hands and feet 

 are quite unlike those of L. pygerythra. Its distinctive characters 

 prohibit it from being regarded as a subspecies of any described form.
