Type. Adult male. B.M. no. 6. 5. 8. 4. Collected loth 

 April, 1905, by J. Steinbach. Three specimens. 



1 should have been inclined to call this bat, which was 

 first obtained by Sr. Dinelli in 1902, a subspecies of 

 P. nasutus, but, as the Paraguayan P. fosteri comes between 

 the ranges of the two, Ave must await further material before 

 presuming that intermediate specimens occur.
