Deals with the recent and fossil species of Auchenia. It is shown that 
there are three S. American Pleistocene species ; viz., A. weddelli , Gerv., 
allied to the Guanaco, but as large as a Horse ; A. intermedia , Gerv., of 
the size of the Guanaco, and showing variations resembling the existing 
Llama and Alpaca ; and a new species, A. minuta , allied to the Vicugna. 
Protauchenia reissi , Branco, is identified with A. weddelli ; and A. castel- 
naudi, Gerv., with A . intermedia. In an appendix the specimens described 
,by Ameghino as Eulamops parallelus ) Auchenia lama t Mesolama angusti- 
maxilla , Stilaucheniaoweni, Auchenia frontosa , and Palceolama leptognatha 
(see Zool. Rec. xxvi, Mamm. p. 44) are identified with A. weddelli ; 
jiyhile A. gracilis , A. lujanensis , and A. (Palceolama) mesolithica ( Zool. 
Rec. 1. c.) are referred to A. intermedia ( castelnaudi ).
