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 pu1)lished in the Proceedings of the Zoological Society 

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

 name Hyonycteris discifera, together with Hyonycteris albiventer 

 ToniesX and Thyroptera bicolor Cantraine § among the synonyms 

 of the Brazilian Thyroptera tricolor Spix. While no si)ecimens of 

 the three nominal and probably valid South American species || 

 are availal)lo for comparison with the Nicaraguan bat, there can 

 be no doubt that the latter differs widely from any ofthe.se. It 

 may be redescribed as follows : 



Thyroptera discifera (Lichtenstein and Peters).
