V. On Remains of a large extinct Lama (Palauchenia magna, Qw.) from Quaternary 
Deposits in the Valley of Mexico. By Professor Owen, F.R.S. 8fc. 
Received March 22, — Read April 22, 1869. 
In the second of Dr. Lunds communications to the Danish Academy of Sciences, entitled 
“ Survey of the extinct species of Mammalia which inhabited the Highlands of tropical 
Brazil previously to the last Geological Devolution,” he includes amongst the Ruminantia 
two kinds of Camelidce, observing :■ — “ Of the genus Camelus I possess the remains of 
two species, one exceeding a horse in size, the other a little less. To Which of the two 
subgroups of this genus the fossils belong, that is, whether to the modern inhabitant of 
the warm regions of the old world, Camelus , 111., or to that now found in the chain of 
the Andes, Auchenia , 111., my insufficient means of comparison will not allow me to 
decide”*. 
Professor Pictet, in his comprehensive ‘ Traite de Paleontologie,’ refers the fossils so 
indicated by Lund to the genus Auchenia , but without, apparently, any additional facts 
or evidence to guide him to this decision f. 
Professor De Blainville, in the Fasciculus of his 4 Osteographie’ relating to the genus 
Camelus , remarks: — 
“ Parmi les pieces fossiles deja assez nombreuses provenant du Bresil, que nous posse- 
dons dans les collections du Museum, je n’en ai encore rencontre aucune qui puisse etre 
rapportee aux Lamas, et je ne vois pas que dans ses Memoires, publies dans les ‘ Actes 
de l’Academie Itoyale des Sciences de Copenhague,’ M. Lund ait fait connaitre, soit par 
des descriptions, soit par des figures, les pieces qui ont servi de base a ces assertions ; 
elles n’en ont pas moins ete reprises cependant dans toutes les compilations paleontolo- 
giques” (p. 123). 
I may remark that M. Lund does not commit himself to any assertion of the particular 
genus of Camelidce to which his fossils belonged, whatever parts he might have obtained 
from the caves at the date of the Memoir above alluded to. 
In his later communication to the Danish Academy, of November 1844, published in 
the twelfth volume of the Transactions above quoted, there appears in the list, p. 8G, 
“No. 12, Auchenia A but all that is subsequently added upon this subject is as follows : —

lated and published in the ‘ Magazine of Natural History,’ by the Rev. W. Bit.ton, M.A., 1840, New Series, p. 1.) 
+ “ Les Lamas ( Auchenia , 111.) paraissent avoir habite l’Amerique meridionale pendant l’epoque diluvienne, 
comme de nos jours. M. Lund en a trouve deux especes dans les cavernes du Bresil ; Tun d’elles surpassait le 
cheval par sa taille.”— 8vo Ed. 1853, tome i. p. 345.
