Size much smaller than in Camelus, and back without

 but anterior premolars sometimes wanting ; upper premolars 

 small ; lower incisors long and procumbent, with the outer 

 pair smallest ; skull with less prominent ridges and relatively 

 larger brain-chamber than in typical genus, and premaxillte 

 articulating with relatively short and broad nasals ; ears

Eestricted at present day to western and southern South 

 America. 



The two species (as represented by wild forms) are 

 distinguishable as follows : — 



A. Size larger, callosities on limbs L. glama. 



B. Size smaller, no callosities on limbs L. vicugna.
