616 On Mammals from Jujuy. 



16. Octodontomys gliroides, d'Orb. 



S. 1403, 1408, 1419 ; ? . 1402, 1404, 1422. Alfarcito, 

 2600 m. 



17. Ahrocoma cinerea, Thos. 



cJ . 1431, 1450. Siena de Zeuta, 4500 m. 



This, the first of the Argentine species of Ahroooma to be 

 discovered, was previously only known from the type- 

 specimen, obtained by Sr. Budin in 1919 at Casabindo, about 

 100 km. to the west. 



"Lives among the rocky volcanic mountains; is very 

 difficult to capture, as other rodents constantly spring the 

 traps set for it, and all efFoits to obtain further examples were 

 without result.-" — E. B. 



18. Ctenomys budinl, Thos. 



cJ. 1451, 1456 ; ? . 1453. Sierra de Zanta, 4500 m. 



c?. 1457, 1467; ?. 1456, 1475, 1493, 1503, 1.508. 

 Higuerilla, 2000 m. 



" I hope that in these Tuco-tucos you will find a new sub- 

 species, as it seems to me impossible that the same form 

 should occur on the bare sandy heights of the Sierra de Zenta 

 and the low damp vegetable soil on which those of Higuerilla 

 were found." — E. B. 



But the original budini was found at the same altitude as 

 the Sierra de Zenta specimens, so that the latter are no doubt 

 typical budini. Those from Higuerilla are a shade darker in 

 colour, as is natural, and appear to approximate more to the 

 low country woodland forms sylvanus and uiibilis, 



19. Lagidium tucumanum, Thos. 



? . 1405 (immature). Alfarcito, 2600 m. 

 Quite of the greyish colour of the Maimara specimenSj not 

 yellow as in L. vuicani fioui Casabindo.
