Mammals from Jujuy. C09 



The three localities at which the specimens were obtained 

 were : — 



Alfarcito. — 2600 metres altitude, situated about 15 km. 



N.E. of Maimara, the jdace where Sr. Budin first 



collected. 

 Sierra de. Ze/*^rt.— Altitude 4500 m., a range of mountains 



running north and south along the eastern Gf\g% of the 



Tilcara Department. 

 Iligiierilla. — 2000 m., in the Department of Vulle Grande, 



about 10 km. east of the Zenta racge and 20 km. of 



the town of Tilcara. 



1. Psendalopex cidpceuft, Mol. 



? . 1410. Alfarcito, 2G00 m. 



? . 1455. Sierra de Zenta, 4500 m. 



2. Conepatns aja.v, Thos. 

 c?. 1411. Alfarcito, 2600 m. 



3. Sciuriis (Mesosciurus) argcntinius, sp. n. 



S. 1496, 1506, 1516 ; ? . 1495, 1504, 1512, 1513. Hi- 

 guerilla, 2000 m. 



A yellow-bellied squirrel with a strong resemblance to 

 S. hnfmanni and griseogena of northern S. America. 



Size about that characteris;ic of Allen's Mesosciurus, Fur 

 rather short and coarse, hairs of back (winter) about 11- 

 12 mm. in length. General colour above buflfy olivaceous 

 brown, approaching " Dresden brown,'' the colour quite like 

 that of many specimens of true Iwffmayini. Under surface 

 clear " ochraceous buff," the hairs this colour to the roots ; 

 demarcation on sides rather sharply defined. Eyes with 

 their upper and lower lids buffy. Ears rich reddish (near 

 " vinaceous tawny "), a patch behind them cinnamon-bnff. 

 Hands and feet strong buffy, like belly. Tail broadly 

 washed with strong butty or ochraceous buffy to the tip, the 

 hairs mostly black at base, then buffy, with a black sub- 

 terminal band and buffy tip. No tendency to a blackish tail- 

 tip, the terminal hairs being the most broadly washed with 

 buffy of all. 



Skull of about the size of that of S. hoffmanni, but it is 

 less bowed and convex above, and (perhaps as a consequence) 

 the incisors are rather more directed forwards (index 67°-90°, 

 as compaied with 80°) than in other members of the group.
