XIX. — On some small Mammals from Salta, iV. Argentina. 

 By Oldfield Thomas. 



Dr. C. Spegazzim, the well-known fungologist of La Plata, 

 has been good enough to present for division between the 

 Buenos Ayres and British Museums a small collection of 

 Bats and Bodents made by him in Salta during the last 

 southern summer season (Dec. 1896-Feb. 1897). 



Among these specimens there are representatives of two 

 new mice, now described, while the other species obtained 

 also deserve some mention. 



1. Vespertilio^ sp. 



a~c. Upper Cachi. 

 d. Viiia. 



e,/. Pampa Grande. 



This fawn-coloured Vesjjertilio I can identify with no 

 species contained in Dobson's Catalogue ; but it may perhaps 

 prove to be one of Azara's species, and 1 do not therefore 

 care to describe it as new. 



A full identification of Azara's bats and murines is very 

 much needed before Argentine specimens, whether from the 

 north or south, can be satisfactorily determined. Thanks to 

 the collections made by Messrs. Perrens, Borelli, Spegazzini, 

 and others, I hope soon to be in a position to publish an 

 identification of all the species described by the Spanish author 

 referred to. 



* I take this opportunity of figuring some of the species described by 

 me in this Magazine (ser. 6, vol. xviii., July 1896), 



t Dr. Kobelt, in the Conch. Cab. ed. ii., Helix, p. 843, pi. xxviii. 

 figs. 4-6, places this species in the subgenus Bostryx ; he evidently did 

 not read the original detcription or examine his specimen with a lens, as 

 he makes no mention of the remarkable sculpture of the nucleus of 

 X. Baroni, which separates it from Bostryx and other genera.
