Mr. O. Thomas 9n small Mammals. 489 
L.—On small Mammals from “Otro Cerro,” North-eastern 
Rioja, collected by Sr. L. Budin. By Ouprteip ‘THOMAS. 
(Published by permission of the Trustees of the British Museum.) 
Arter making the collection at Chumbicha, Catamarca, of 
which an account is given in the ‘ Annals’ for January 1919, 
Sr. Budin travelled westwards some 30 miles, ‘over the 
Cerro de Ambato to “another hill,” or range of hills, for 
which he could find no recognized name, but which, after 
consultation with the authorities of the Geographical Society, 
I suppose to be an unnamed range running southward 
from the Cerro Nunorea. Although Srv Buin considered 
himself to be still in Catamarca, and labelled the specimens 
accordingly, the distance and direction from Chumbicha show 
that he must have crossed the frontier into Rioja. 
Under these circumstances I have decided to use Sr. Budin’s 
fancy name of ‘ Otro Cerro,” as put on his labels, but with 
correction as to the province, If more exact definition can 
be obtained from him it will be published later, but for the 
resent the locality may be stated as 45 kilometres west of 
Chumbicha, the specimens being taken at an altitude of about 
3000 metres. 
The collection contains quite a number of interesting 
species, of which the most striking are the new Lagidium, the 
skunks, and tuco-tuco, while the good series of such forms as 
Phyllotis and Graomys have enabled me to make further 
study of these difficult groups. 
Like all Sr. Budin’s recent specimens, the skins are beanti- 
fully prepared, and thus together form a very valuable addi- 
tion to the National Collection. 
Azising out of a suggestion by Sr. Budin, I should like to 
propose that certain Spanish and other colloquial terms 
should be definitely restricted to particular genera, so as to he 
available for vernacular names. ‘The native words used as 
names by Mr. Perry Simons, Sr. Budin, and others have 
generally been rather vaguely applied, but might easily be 
pinned down to special genera, where they would be of great 
convenience, 
Thus I would take Azara’s name of “ Hocicud»” for the 
species of Oaymyeterus and “ Laucha” for LHesperomys. 
Then Andinomys might be “ Chozchorito,” Phyllotis * Peri- 
cote,” and Oryzomys “Coludo,” which equals “ Long-tail.” 
Other colloquial names are already well kuown, but where 
there are none I shall hope, with Sr. Budin’s assistance, to 
suggest some which might be suitable and convenient.
