THE CENTRAL AMERICAN THYROPTERA. 

 BY GERRIT S. MILLER, JR. 



Three specimens of Thyroptera, collected by G. E. Mitchell on 

 the Escondido River at a point about fifty miles from Bluefields, 

 Nicaragua, and now in the collection of the United States De 

 partment of Agriculture, are clearly referable to the species de 

 scribed by Lichtenstein and Peters in 1855 as Hyonycteris dis 

 cifera* This bat was recognized as a distinct species by Tomes 

 in a paper published in the Proceedings of the Zoological Society 

 of London for 1856 (p. 179), but Dobson, in 1878,f placed the 

 name Hyonycteris disci/era, together with Hyonycteris albiventer 

 Tomes J and Thyroptera bicolor Cantraine among the synonyms 

 of the Brazilian Thyroptera tricolor Spix. While no specimens of 

 the three nominal and probably valid South American species || 

 are available for comparison with the Nicaraguan bat, there can 

 be no doubt that the latter differs widely from any of these. It 

 may be redescribed as follows : 



Thyroptera discifera (Lichtenstein and Peters).
