MAMMALS. 159 



was described at lengtli and figured by Harlan in tbe Annals of the New York Lyceum. On 

 the scattering of the Philadelphia collection, it came into the possession of the Philadelphia 

 Academy of Natural Sciences, of whose magnificent museum it now constitutes a highly val- 

 uable component. 



The next specimen was received by the Zoological Society of London a few years later, and 

 its osteology described in considerable detail by Yarrell. As, however, the skin was prepared 

 for the museum, the bones of the feet were left attached, and could not be described with the 

 other portions of the skeleton. This animal was preserved in spirits, without the intestines, 

 and of course these could not be described. 



The third specimen made known to naturalists was one in possession of Dr. Gemminger, of 

 Munich, much more perfect than any of the others, as it was preserved entire, in excellent con- 

 dition, in alcohol. This was purchased by Dr. Hyrtl, of Vienna, ^'..o has for some time past 

 been engaged in preparing an elaborate monograph, to include all the details of its anatomical 

 and external structure. From the well-known ability of Dr. Hyrtl, there is no doubt that the 

 subject will be exhausted, as far as a single specimen will enable him so to do. The memoir 

 will be published in the Denkschriften of the Imperial Academy of Sciences of Vienna, and may 

 possibly have already appeared, although it has not yet reached this country. Dr. Hyrtl also 

 obtained a dried skin of the Pichiciego, making, as far as known, three specimens in Europe. 



While Lieutenant Gilliss was in Chile, his attention was called to this subject, and he made 

 several fruitless efforts to procure specimens during his stay. About a year after his return, 

 however, some friends having procured a fine mounted individual, presented it to him, and it 

 is now in his possession, having served as the original of the accompanying plate. Another 

 specimen was sent to Lieutenant Pheljjs, who gave it to the museum of the Cleveland Academy 

 of Natural Science. 



It .will thus be seen that the six specimens on record are equally divided between Europe 

 and America. There may be others in museums, but I have never seen mention made of them. 



Not much is known of the habits of this curious animal, beyond the fact of its existing in 

 the vicinity of Mendoza, and, on account of its nocturnal habits^ appearing to be rarer than it 

 really is. 



AUCHENIA LLAMA, Desm. 



Auchenia llama, Watekhouse, Zool. of Beagle, 1838, 26. 



Llama guanaco, G-ay, Hist, de Chile, Zoologia, I, 1847, 153. 

 I have cited only the above synonymes of the Guanaco, as, according to Tschudi, there are 

 really several species in what has hitherto been considered as one, and I have not now the ma- 

 terial for deciding the question. All the specimens brought by Lieutenant Gilliss belong to 

 the robust form living wild in the mountains of Chile, and referred to by the authors above 

 quoted. This extends from the wooded islands of Tierra del Fuego to the Cordilleras, in Peru. 

 Going in herds sometimes containing hundreds of individuals, they are generally shy and 

 extremely wary, though sometimes, like the American antelope, their curiosity gets the better 

 of their discretion^ and they will approach the sportsman, if he lies on the ground and kicks 

 up his feet in the air, holds up a handkerchief, or otherwise attracts their attention. 



The Guanaco of Chile has usually been considered to be the Llama of Peru in a wild state. 

 As above remarked, however, Tschudi makes them different species. 



Note by Lieut. Gilliss. — "The Guanaco may be found on the entire Andean chain, in 

 Chile, and is certainly the most abundant of the larger quadrupeds. It attains maturity in 

 rather less than one year, but continues slowly increasing in size during several years. As 

 they feed just below the snow-line, and the young are less fleet than full grown animals, the
