Size much smaller than in Camelus, and back without 

 hump ; adult dentition normally : i. ^, c. -]-, p. f , m. f = 32, 

 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 premaxillae 

 'articulating with relatively short and broad nasals ; ears 

 rather long and pointed ; feet narrower, with the toes, each 

 of which has a distinct plantar pad, more separated than in 

 Camelus ; tail short ; coat long and woolly ; teats two. 



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.
