In Puihi the piomaxillae do not reach the nasals, in 

 Pudelhi they do. 



In Pudu the hoof?, botli largo and small, are of the normal 

 shape ; in PitdeUa they arc unusually narrow and pointed. 



In Pudu the middle lower incisors are notdisproportionally 

 larger than the others, being barely twice the breadth of the 

 second pair ; in Pudella their blade is three or four times 

 the size of that of /j, which in turn is little larger than i^ 

 and the canine. 



In Pudu the naked rhinariuni is but small, in Pudella 

 unusually large, projecting backwards in the middle line. 



No doubt the two genera are closely allied, but, in the 

 absence of any connecting links, I think a special name for 

 the Andean form is advisable.
