mano Luan. » It might follow from this that Molin a in the 

 first rank had a Peruvian animal in his mind, when he gave 

 the name, but it is also clear that he regarded the Guanacos 

 from Peru and Chili as identical. As the Peruvian name has 

 been used it would perhaps ha ve .been near at hand to seek 

 the type for the name in Peru, if nötning directly contradieted 

 such a proceeding, but that appears to be the case, at least 

 so far that the name cannot be applied to the small Peruvian 

 race described above. When describing the Guanaco Molina 



says: »la sua altezza misurata al sito delle gambe 



dinanzi di quattro piedi, e tre pollici» (1. s. p. 318). If it is 

 assumed as most probable that this means spanish feet and 

 inches the height of Molina's Guanaco would be about 111 

 cm. A Guanaco from Tierra del Fuego which has been mounted 

 in this museum in accordance with the measurements of 

 the skeleton belonging to the same specimen stånds 113 cm. 

 at the withers which thus is in rather close correspondence 

 with Molin a's measurements. This proves that the author 

 quoted has had as a type not a dwarfed form such as Dr. 

 Sefve's specimens represent. J. J. von Tschudi has also 

 in his work »Untersuchungen iiber die Fauna Peruana» (St. 

 Gallen 1844 — 1846) (1. c. p. 225) recorded dimensions of a 

 male Guanaco which are larger than the corresponding ones 

 of the domesticated Lama. According to him the male Gua- 

 naco of Peru has a height at the withers of 39 inches. If this 

 means French inches Tschudi's Guanaco must have been a 

 large animal standing about 126 cm.; if Suisse inches about 

 117 cm., but in neither case it could have been smaller than 

 the Patagonian animal. It is thus clear that Peru must be 

 inhabited by a large Guanaco as well, and it appears therefore 

 probable that the small Guanaco collected by Dr. Sefve must 

 constitute a local race confined to a certain district only. It 

 must then receive a new name, and I take the liberty of calling 

 it Lama huanachus cacsilensis from the place where it has 

 been found.
