small Mammals from Jujuy. 137 



hot come to liaiul, hut it ap[)ear3 from the labels that the 

 sjx'cimens were coUt'Cted at (1) Maiinara, 22o0 m., and 

 (2) Ceno de Lagiinita, E. of iJaimaia, -toOO m., both pUices 

 being situated near Uniahuaca (or Huinahuaca), in tiie centre 

 of tlie province of Jujuy. 



A study of this collection reveals a very striking similarity 

 between the fauna of Jujuy and that of the Eastern Bolivian 

 highlands for some four hundred miles furtlier north. For 

 tiie general facies of the collection is very like tliat of the 

 series obtained by the late P. O. Simons in the country 

 round Cochabamba *, quite a number of the species being 

 absolutely identical, and a very similar fauna extends north- 

 westwards at least as far as Ija Paz. 



The collection contains fifty-four specimens belonging to 

 fourteen species and subspecies, of which five are new. 

 Sonie notes by Sefior Buiiin on the habits and native names 

 of the species are inserted below.
